The Urban Kitchen Gardener by Tom Moggach

I'm so tired of the empty ghost-written celebrity/TV driven cookbooks which have no heart or soul. The love and thought is evident in The Urban Kitchen Gardener, for this is a book actually written and lived by the author, Tom Moggach. Suggestions such the 'daily patrol' of your plants, to tune into them, accompanied perhaps by a strong cup of tea, are born of experience and intuition. Tom's book is vital for the city gardener and, at the same time, contains inspiring recipes for the green-fingered cook, so the Secret Garden Club, devoted to growing their own food, is a fan!

A few months ago, on a dusty but eye-opening trip through Georgia, the former Soviet republic, I met Tom Moggach. He was reporting for The Food Programme on Radio 4, exploring the markets in particular. I tailed behind him as he fearlessly bought mysterious seeds wrapped in wriggly writing newspaper cones from a market stall. I grew some of these seeds myself, unsure what would emerge from the soil a few weeks later.
I also led Tom astray from the path of legality when I found tiny purple Parma violet plants, sweet and sickly like confectionary, growing wild at a central Georgian vineyard. We used our water bottles to make mini protective greenhouses for these plants and smuggled them home in our pockets. My Parma violets* are doing very well in my London garden, despite the sodden British weather this summer.

I've always struggled with growing coriander, which is a shame because it is probably my favourite herb. Tom has useful tips, telling you to sow it every couple of weeks to retain a regular source of leaves for use in cooking, to only use seed less than two years old, to choose the brown unpolished seed to germinate. He also uses fresh green home-grown coriander seeds in his cooking which sounds deliciously intriguing.
The book is divided into vegetables, herbs, leaves (for salads), fruit, edible flowers; each section has enticing recipes such as chilli cornbread, fresh coriander and coconut chutney, home-cured mackerel (makes a change from the usual gravad lax), tomato and lemongrass rasam (a kind of South Indian soup).
Tom's growing stuff that we've not tried: I've never eaten mouse melons, small and crunchy like cucumbers, nor have we grown shisho leaves, a Japanese ingredient with a distinctive flavour. Yet.
It is equally good as a cookbook, offering genuinely innovative recipes, as a gardening manual for small urban spaces. Tom Moggach teaches school children to garden, therefore his style is approachable as well as informative. This is a great book to inspire and instruct beginner gardeners.

Buy Tom's book here or here on Amazon. Highly recommended. Makes you feel good, that real authors are still writing heart-felt personally researched books rather than the empty soulless drivel that passes for publishing nowadays.


*must make sure I split these after spring flowering, to propagate some more. I'm not sure of the exact cultivar.

Salad days

A rose-like radicchio plant in the sunshine.
Once you have raised your first homegrown crop of salad leaves it will be very difficult to go back to bagged salad at the supermarket. Those cellophane pillows are highly convenient, but your homegrown leaves will will be juicier, spicier, tastier. You’ll know your own leaves haven’t been sprayed with anything or washed in chlorine. You’ll also be surprised to find out how long your homegrown leaves stay fresh in the fridge compared to bagged salads which start to sag and look mushy the minute you open the bag.

The Secret Garden Club looked at the very wide variety of leaves available to grow yourself, and why you might want to do that.

First, some advantages of growing your own salad leaves:
  • Choice – raise the tastiest varieties
  • Versatility – you’re not limited to what the supermarket wants you to buy (which will be stuff that looks good and keeps well, rather than the most delicious tasting)
  • Peace of mind – you’ll know the exact provenance of every leaf
  • Convenience – a pot of leaves just outside the back door, or on a windowsill, means you’re only ever two minutes away from a salad
  • Value for money – I’m always hesitant to say you’ll save money because once you add up the money for seed, pots, compost, and so on, I’m not sure it’s cheaper. It probably is. But if you get into it and start treating it as a hobby then the temptation is to spend money on it.
You don't have to restrict yourself to pulling leaves from a lettuce - there are plenty of other types of salad leaves available.

What to grow, where and how

Traditional lettuce – the type which you grow as single plants, spaced out, in order to mature and develop multiple leaves. You then harvest the whole plant at any one time.

a nutty tasting heart
This is a crop for the vegetable patch – lettuces need time and space. The best way to sow lettuce seeds is indoors in modules. Each plant can be planted out in the vegetable bed when the seedlings are big enough to handle. From the seed germinating to you eating a full-grown lettuce will take about 13 weeks.

Lettuce works best as a summer crop although they will appreciate some shade in high summer. For winter salads, I grow radicchio (see the picture at the top) and chicory. As with summer lettuce we sow the seeds in modules indoors in May-June and transplant the seedlings outside when they've outgrown the plastic pods. Both radicchio ad chicory have a robust, slightly bitter flavour, and can be cooked as well as eaten raw.

Chicory can be forced in the dark to make the leaves grow whiter, more tightly packed, more tender and less bitter. Grow your plants in pots, and in autumn, cut back any growth to leave a short stub above ground. Bring the plants indoors, somewhere unheated but frost-free - a garage, or cellar, perhaps. Place a bucket over each pot to ensure all light is excluded. It takes a few weeks, but the plants will send out white chicons, which can be cut and eaten as white chicory.

Cut and come again lettuce, also known as CCA, or Mesclun, or mixed leaves. This is a much quicker and more space-efficient way to grow lettuce: instead of thinning the seedlings and letting each plant grow to maturity, you snip leaves from the plants on demand - whenever you fancy a bit of salad.  This is a quick way to raise salad – you can be eating your leaves 4-6 weeks after the seeds germinate.

Sow the seed thickly in a container or in the kitchen garden and let the seedlings grow without any thinning. Once the leaves are a reasonable size, snip them off at the base with scissors. Don’t pull whole plants up – you want the seedlings to continue to produce new leaves after each harvest.

You can also grow different varieties in the same container so that you always have a mixed salad on tap.

What you won’t get is that lovely firm, nutty heart that you get in a Little Gem lettuce or similar. If you like lettuce hearts, like I do, it’s always worth growing a few for this alone. But my main salad crops are these, mixed leaves.

Lamb's lettuce growing in an old
fruit crate.
Mixed leaves grow really well in containers (which whole lettuce plants don’t) and so you don’t need a garden at all. You can grow on a windowsill, indoors or outside – see the corn salad trough. You can grow in a reclaimed container – see the fruit crate.

You can mix and match varieties to your heart’s content to get the best taste possible from your salad or so that you can vary your salad flavours. At the Secret Garden Club we’ve got a standard leaf mix here and also an oriental mix here.

This crate was devoted to rocket, which is now well and truly in flower – don't let them go to waste, they're delicious and can be added to your salads too – and can be resown soon.

Micro-leaves
You may have seen these in fancy restaurants: tiny perfect salad leaves that still pack a punchy flavour. I suspect that if you’re trying to feed a family with salads that these may be too dainty but they’re useful to have around for a quick garnish.

All they are is seedlings. There’s no special treatment, it’s not like growing bonsais. You can use a shallow seedtray, or a small pot, because the plants won’t grow big enough to put down deep roots. Fill with seed compost, firm lightly and water. Sprinkle the seeds over evenly so that they rest in a single layer.

Cover v lightly with more compost. Then cover the tray – I’ve got the clear plastic lid but you could use a clear polythene bag – and place somewhere warm.

At this time of year, you’ll see the first seedlings in about 48-72 hours. Remove the lid but keep warm and sunny – a south-facing windowsill is ideal. The microleaves will be ready in about two weeks – again, this is a fast-growing time of year. In spring and autumn it will be more like 4 weeks.

Be brutal when cutting them for salad use, it’s not as though you’re growing them as cut and come again. Then resow – after only 2-3 weeks, you can re-use the soil.

Good for microleaves: coriander, most mixed salad leaves, oriental leaves such as mustard and mizuna.

Thinnings
Thinnings or leftovers from the vegetable patch made great additions to the salad bowl. Beetroot, chard, spinach and cabbage are all tender enough and tasty enough in seedling form to be used in salads. So when the time comes to thin or transplant the seedlings, don't throw away or compost the plants you thin out. Take them home, give them a good trim and wash and use in a salad.

This year I potted up the cavolo nero seedlings which didn't get transplanted into the main bed, transferring them instead into a 20cm pot with the seedlings evenly spaced out in it. These pot plants have leaves which are smaller, less fibrous and more tender, ideal for tearing up and using in a robust winter salad.

With beetroot, chard and spinach, I deliberately sow them thickly so that there is plenty of thinning to be done, and the thinnings always make up a nice spring salad. Similarly, when I transplant leeks the seedlings left over are delicious and delicately flavoured in a salad.

And don’t forget pea shoots. You can now buy these at great expense as part of a supermarket bagged salad – instead, why not sprinkle leftover pea seeds over a pot and use the seedlings for salads?

It also feels like food for free, which is always pleasing, as it’s kind of a by-product from another crop.

Edible flowers
We covered edible flowers in some detail at the Secret Garden Club in June. These are always good for adding stunning good looks and a delicate contrast in texture and flavour to a salad. Adding flowers to a green salad will immediately lift it out of the ordinary visually. Our post on edible flowers explains how to pick and prepare flowers for culinary use.

Nasturtiums, shown above, are first choice for adding to salads - and the leaves, finely shredded, will give any salad a good peppery kick as well. The flowers are plentiful at this time of year and are easily picked a separately to give salads a shot of hot orange or vibrant red.

Also good in salads are chive flowers, bergamot, violas and marigold petals.

Sprouting seeds
If we can have microleaves, I suppose these must be nano-leaves. Most people are familiar with beansprouts as bought in the supermarket, and possibly – if you’re feeling very healthy – alfalfa sprouts.

These are seeds which you sprout in water just to the stage of producing the first leaves, which can then be eaten raw or stir-fried. They have a delicious flavour and crunchy texture and add variety to salads. They are also highly nutritious - each sprout packing all the nutrients needed to grow the plant from germination to its first true leaves.

The beansprouts you buy most readily in the shops are grown from mung bean seeds, but of course you can experiment and find the ones you like the best.

I think mung bean sprouts can be a bit bland – my favourite for flavour are adzuki beans and also chickpeas – which can be quite large.

Here’s how to grow them. You will need a glass jam jar, with a fine mesh lid or covering. A cut-up square from a very clean pair of tights or stockings stretched over the top and secured with a rubber band is a perfect solution.

Rinse a handful of beans, drain well and put in the jar. Stretch the mesh over the top and secure - with a rubber band or similar. Rest the jar facing down at an angle so that any excess water drains away.

Twice a day, once in the morning, once in the evening, you need to pour water into the sprouts, either through the mesh or with the mesh removed. Then replace the mesh, swirl the water around to rinse the seeds thoroughly, and drain, resting the jar at a downwards angle again. The jar should be kept in the dark - but choose a cupboard you open and use fairly often or it's all too easy to forget about them!

Don't forget to rinse the jar twice daily or the seeds will dry out and not grow. Don’t forget to drain them after each rinse – if they sit in water they’ll rot.

The sprouts should germinate within a week. Use them when they about an inch or two long and before they grow their first leaves.

With a combination of all of these you can have salad on tap 365 days a year.

(Incidentally, do you know the trick to keeping bagged salad fresher? Once you’ve opened the bag and used some of the contents, fold the bag back up very tightly, getting as much air out as you possibly can, then seal the bag – I use Scotch tape. But if you have strong ziplock bags you can transfer to one of these and flatten out as much air as you possibly can before sealing and returning to the fridge.)

Kitchen table hydroponics


Mixed salad seedlings growing hydroponically, without soil.

Growing plants hydroponically, or without soil, is a clean, and resource-efficient way to successfully raise a variety of produce. Yet it seems to be viewed with a great deal of suspicion in many quarters. This extract, from Green Harvest, an Australian website, is reasonably typical:


"A large quantity of the salad greens available in the supermarket are grown hydroponically, the complete opposite of organically. Hydroponics is a growing system that bypasses the soil in favour of a 'nutrient soup' made from chemical fertilisers fed directly to the plants. The lettuces in the supermarket might look like a lettuce but chemical cocktail might be a better description."

I don't know what they put in bagged salad in Australian supermarkets, but I wonder what the author thinks soil consists of, if it's not a chemical cocktail itself.

Conventionally grown plants have their roots in soil, which is typically made up of minute rock particles, organic matter (material which was once living, now decayed) and water. The more fertile the soil, the more chemically rich it will be, especially in nitrogen, potassium, and phosphorus, the three main nutrients needed by plants.

However, the soil isn't necessary for plant growth; it's only there as the medium for delivering water and nutrients to the roots. Hydroponic growing eliminates the soil and concentrates on getting water and nutrients directly to the roots.

Growing hydroponically isn't the "complete opposite" of organic growing. You can incorporate many organic elements into a hydroponic set-up - using organic coir as a growing medium, for example. I suspect that what makes people suspicious of hydroponic systems is the micro-managed nature of it.

What an organic philosophy and hydroponic growing have in common is the desire for sustainability. Both methods are far less fuel-intensive than using manufactured fertilisers. Organic systems aim to reduce soil erosion and exhaustion with the addition of organic matter; in many hydroponic systems, the growing medium can be reused many times. For example, perlite, the rock granules which are often used to anchor the roots, can be sterilised in a microwave and then used again for the next batch of hydroponically-grown seedlings. The micro-management that delivers precisely the nutrients needed to the growing plants also means there is far less waste.

If you look around on the Internet you'll find off-puttingly long lists of technical equipment required for a hydroponic set-up: pumps, filters, hoses, lights. You would be forgiven for thinking it's less like growing plants and more like a laboratory experiment.

However, much of the expensive and hi-tech kit is needed for hydroponic growing on an industrial or commercial scale. To successfully grow salad leaves an herbs on a windowsill, some pots, water and a soil-less growing medium is all you really need. And your 'nutrient soup' of course.

Hydroponics
+ Sustainable
+ Efficient use of resources - less waste
+ Takes up relatively little space, with high yields
+ Versatile – does not need fertile soil, can be grown anywhere
+ Cleaner to maintain

- Cannot be called organic
- Lot of management required to get the balance right
- Leaching if not managed properly
- Only suitable for some plants

We used a simple base kit from The Achiltibuie Garden. Based in the north-west highlands of Scotland, this company specialises in developing hydroponic growing systems for domestic use. Many of their systems are modular, so that you can add extra units to the base kit if your needs increase. This windowsill kit shown below, is good for raising salad cut-and-come-again leaves and herbs.

The kit: long plastic trough and four pots. The growing medium, a mix of perlite and vermiculite, containers with liquid nutrients and four packets of seeds.

The absorbent material which fits into the slotted base of each pot will take up water and the liquid nutrients into the pots.

The pots are filled with the perlite/vermiculite. This growing medium is there to anchor the roots and so keep the plants stable. Its structure means there is still air held in the growing medium and its ability to hold water means the plants can access the liquid feed.
Seeds are sown in each pot and lightly covered with more perlite/vermiculite.

The pots are covered to keep the seeds dark until germination. The funnel in the middle delivers water to the base of the trough, from where it can be taken up by the absorbent wicks protruding below each pot.

First signs of germination.
Once germinated the seedlings are covered with a strip of fleece to provide a protective 'micro-climate'.

Topping up the water beneath each pot via the funnel.
Our seedlings ten days after germination. From the bottom up: chervil, dill, salad mix and lamb's lettuce.

We'll be discussing hydroponic growing in more detail in a future Secret Garden Workshop, looking at ways to set up a simple system in a restricted space and the most suitable plants for this kind of set-up. Keep an eye on our Events pages for scheduled dates.

Dig this - potatoes and garlic fresh from the soil


We planted garlic at the Secret Garden Club back in December - on the shortest day of the year, as is traditional. Continual rain and cool temperatures aren't ideal for garlic, but our bulbs have survived and swelled well.

Once dug up, the bulbs need all that excess soil removed. Usually, in July, it's a case of rubbing off dryish dirt; this year the mud needed to be washed off. Garlic can be eaten fresh, but to store bulbs, hang them up somewhere light and airy to dry out until the outer skin is papery - about 2-3 weeks.

In February, we planted our Secret Garden Club potatoes in a bin-bag - an easy space-saving way to raise a crop of spuds. Again, the weather hasn't been very helpful; normally, we would harvest these early Lady Christl potatoes from mid-June. This year they have been about a month late to develop to a decent size. 

The crop can be harvested just by up-ending the  bag in which they have grown. The compost using for growing the potatoes makes an excellent top dressing for the winter.

If you attended our garlic workshop back in December or the potato masterclass in February, do let us know here how you got on with raising your own produce. We'll be harvesting our onions and maincrop potatoes next month - a good few days of sun now should just finish the onions off nicely.

Edible Flower Secret Garden Club in pictures

Christina ran the gardening workshop, teaching people which flowers are edible and how to grow them. She also demonstrated how to distill your own rose water and orange flower water, so the rain wasn't a problem, we took the workshops indoors. These are a few pictures from the edible flower supper we served our guests.

All things bright and beautiful: edible flowers

Flowers are definitely due for a comeback on your dinner plate. Edible flowers have almost vanished from our tables: over the last 150-200 years they've been relegated to the side of the plate as a garnish at best, or into a vase in the centre of the table as decoration.
Yet for centuries flowers were considered an integral part of food the world over. The Romans used flowers such as dianthus (pinks), lavender and carnations. The Tudors ate all these and many others such as roses, cowslips, violets and bugloss. Households would make their own distilled flower waters, as well as expecting the kitchen staff to produce floral syrups, pastes, oils and vinegars. 
People would also make their own wine from wild flowers. Elderflower wine, or elderflower champagne seems to be about the only one that is still being made by people today. But you'll have read about cowslip wine in classic novels - there's mention of it in Cranford, by Mrs Gaskell, for instance. Vast quantities of cowslips were gathered to make wine: one internet recipe I found requires several quarts of cowslips to make the same liquid quantity of wine.
You would be surprised to discover how many of the flowers growing in your garden or readily available from garden centres are not only edible but delicious. As well as adding new and complementary flavours and textures to a dish, flowers are of course strikingly attractive. Fresh blooms scattered over a green salad will look - and taste - stunning.

Our Secret Garden Club workshop discussed how to grow edible flowers, with a detailed overview of which flowers can be eaten and how best to use them in your cooking.
There are a few basic rules to follow when foraging for edible flowers:
  • 1. Don’t try to eat any flower unless you’re 100% certain what it is.
Not all flowers are edible and some are toxic – we’ll see some in the Secret Garden today. Don’t assume that if the leaves, or roots are edible then the flowers will be too (tomatoes, potatoes). Don’t assume that just because close relatives are edible, then the rest of the family will be too (sweet peas vs mange tout).
Many are neither poisonous nor palatable: they just don’t taste very nice or can be indigestibly fibrous.
  • 2. Know the provenance of any flowers you plan to eat.
Even when you know what it is, don’t just pick any old flower and eat it. Flowers that have been sprayed with pesticides or other chemicals, or that grow by the roadside, should be avoided. 
  • 3. If you suffer from hay fever or any other plant allergies, be extremely cautious about eating flowers.
Flowers contain pollen which is a well-known allergen. Even if you don’t have these intolerances, try a little bit, like a food tester, the first time you taste a particular flower.
In any case, if the stamens – the interior stalks which carry pollen – are at all prominent, we usually remove them before eating the flower, as they and the pollen can taint the flavour.
Having got what sounds like a list of negatives out of the way, let’s look at some flowers which are not just edible but delicious.

Roses
Roses are one of the most familiar edible flowers.

Crystallised rose petals
Crystallised rose petals are well-known, although you can crystallise any edible flower which has sturdy enough petals to withstand being painted and covered with sugar. Primroses, violets and hollyhocks are also delicious when crystallised and look amazing too.
There are two ways in which you can crystallise flower petals. The first, and the quickest, is suitable for flowers that you will use straightaway as they won’t keep for long. As well as the flowers themselves, you will also need a paintbrush, an egg white and caster sugar.
Pick your flowers and separate the petals if you are going to crystallise just these. The best time to pick flowers is in the morning after the dew has dried off but before the sun is too hot. Go over your picked flowers and check for insects – especially bees and earwigs, but also, especially with roses, blackfly and greenfly.
With roses it is easier to crystallise the petals rather than the whole flowerhead. Pull the petals off gently, and remove the little white lip at the base of the petal.
Lightly whisk the egg white until it’s foamy - this is just to disperse any globular bits. Then take a clean paintbrush and paint each petal with the egg white, both back and front.
Then dredge, or sprinkle with caster sugar – or ‘wipe’ the petal across the sugar. We found dredging with a tea strainer gave the best and most even results.
Lay the petals on greaseproof paper on a rack and dry out in the airing cupboard or a similar warm place for 24 hours – then use as soon as possible.
The second method uses gum arabic, which you can buy from chemists or cake decoration specialists. Dissolve the gum arabic in rosewater or alcohol such as vodka in a solution of one part gum arabic to three parts fluid. You do this by putting the gum arabic in a screwtop jar with the fluid and leaving it to steep – this will take about 24 hours. Then paint the petals with the gum arabic, dredge with sugar and dry as before.
Petals crystallised this way will last about a month.

Making rosewater
Making distilled rosewater is not that difficult and doesn't require specialist equipment. Once made, this beautifully fragrant liquid can be used to add scent and flavour to jellies, meringues, and fruit syrups. There are lots of rose bushes in the Secret Garden, all of which have petals suitable for eating, but for making rosewater we only want the most fragrant of blooms.
The best rose petals are those from a flower which is past the stage of being a bud and is opening out but is not quite in full bloom yet, and certainly not overblown.
How to make rosewater
There are a number of ways to make rosewater. You can simply steep rose petals in water, bring it to the boil and let them cool, before straining the mixture. You'll end up with a coloured liquid that might well be a bit sludgy and won't keep for very long.
Not much more effort is required to make distilled rosewater, which is clear and will keep for much longer.

You will need:
•Several handfuls scented rose petals, separated from the flowerhead and with all bits of stalk, leaf, etc, removed
•A large non-reactive pot with a curved lid
•A bowl which will fit into the pot
•A trivet, half-brick or heatproof weight to go underneath the bowl
•1-2 bags of ice

1. Put the trivet or brick in the middle of a large pot.
2. Pack the rose petals around it up to the level of the top of the trivet or weight. Pour cold water over the rose petals until they are just covered.
3. Set the bowl on the trivet or weight, put the lid on the pan and heat up to boiling point.
4. As soon as the water in the pan starts to boil, put a bag of ice on the inverted lid. Turn the heat down to a simmer.
5. As the steam rises from the rose-infused water, it hits the underside of the lid, which thanks to the bag of ice, will be cold. The steam will then condense and run down the curved lid in rivulets before dripping into the bowl you set inside the pan. After 20-30 minutes, you should have a bowlful full of clear rosewater, which can be lifted out, cooled and decanted into an airtight jar.
Once the water is boiling, it's advisable to check once or twice that your set-up is working and that the rose-infused water is indeed filling the bowl. Carefully lift the lid to check everything is in place, then leave for around 20 minutes before checking again. Once you have the desired amount of water in the bowl, turn off the heat and carefully lift the bowl out of the pan. You should have beautifully scented rosewater.
This rosewater can keep for up to a year, although it’s probably better to make fresh batches for cooking.

Some notes on growing roses

  • Roses are highly versatile plants: you can buy them for the patio, as small bushes or standards, or to plant in the open ground as bushes, or rambling over a hedge or climbing up a wall or fence.
  • The flowers can be any colour from white to cream, yellow, orange, pink, red, purple, and that elusive blue rose.
  • While new varieties are being bred all the time, there is always interest in old-fashioned roses.
  • Not all roses have scented flowers (although I'm not quite sure what the point of an unscented rose is).
  • Roses like fertile well-drained soil. You can dig in some bonemeal when planting.
  • Prune well in early spring – February is a good time. Cut off dead wood altogether, then cut green stems down to above a notch or bud.
  • Prune climbers more lightly than bushes.
  • Don’t plant in the same spot where a rose has previously grown - roses are prone to too many soil-borne diseases to guarantee plant health.
  • Roses are notorious for attracting greenfly and blackfly. If you are contemplating using the petals in cooking or for making rosewater, don’t spray with anything!
  • Otherwise try a garlic dilution spray on the leaves.
  • Or try companion planting: chives planted at the foot of rose bushes look very attractive, especially with their mauve pom-pom flowers. The allium scent is said to put off greenfly and blackfly, much as the garlic dilution does.
  • Marigolds are also pest repellents, but you will usually be planting them out later in the year (about May), by which time the pests may have got a stronghold.
  • And don’t forget rosehip syrup – technically this isn't the flower you are eating, but an utterly delicious way to enjoy your roses and one that transports me straight back to my childhood.
Herb flowers
Lots of guides to herbs will talk about the need to pick herbs before they flower, as though the act of  flowering does something terrible to the flavour of the herb.
In truth, a plant which is concentrating energy on flowering isn’t going to produce the most flavoursome leaves, but what these people overlook is that herb flowers often taste good too and also, of course, look decorative on the plate or as a garnish.
Edible herb flowers include:

Basil
Basil flowers are small and white and taste similar to the leaves. Just as basil leaves go well with tomatoes in salads, etc, so do the flowers for dramatic effect. Or try a pesto with basil flowers as well as the leaves for an unusual twist.
In the UK, grow basil indoors for best results. They will attract aphids for one thing, but also the leaves grow best and most succulently when not windblown or left to the vagaries of our weather.
Lemon basil flowers have an intensely lemon basil flavour and are almost worth growing for the flowers alone.

Sage
Different varieties, eg, purple, variegated, pineapple sage, all edible, tasting similar to the leaf. 

Rosemary
Flowers appear in late winter and continue through spring. The flowers on most varieties is a beautiful pale blue but there are a few pink ones.
Rosemary flowers make a delicious and very pretty flower butter. Back in January when we talked about herbs and medicinal plants at the Secret Garden Club I mentioned briefly the idea of making rosemary butter and freezing it as a way of preserving the rosemary. I reckon rosemary flower butter is a step up from that.  The blue also looks stunning set against the red of tomatoes or peppers in a salad.

Chives
One of my favourite flowers both to look at and to eat. Remove the stalk and pull off the petals, scattering them over salads, home-made pizza, jacket potatoes or potato salad.
Chives are a versatile plant: they grow well in most soils. Once established the plants will grow clumps which can be divided to give you more plants.
They are also good as a companion plant as the onion scent is off-putting to greenfly, blackfly and the like. So they are a good bet to plant under roses or around anything that is vulnerable to aphids (eg, lettuces).

Garlic chives
Garlic chives are every similar to chives although they have slightly flatter and larger leaves, and a distinct garlic tang to both leaves and flowers. The flowers themselves are white and extremely decorative as well as tasty.

Dill
Dill is a fast-growing annual herb with frond-like leaves with a strong aniseed flavour. The flowers have a similar taste, and it’s useful to know that they’re good to eat because dill is prone to bolting as soon as you get a spell of dry weather. So don’t despair, use the flowers instead of the leaves.
Put whole flowerheads into cucumber pickles for a dill flavour and attractive looking brine.

Thyme
The tiny flowers taste similar to the leaves, and are good scattered over freshly cooked vegetables such as broad beans, carrots or turnips. They can be fiddly to handle but try to remove as much green stalk as possible.
Thyme is a Mediterranean plant and likes sun, poor soil and not too much watering. It can be grown from seed but it’s much easier to grow one plant and then divide it in spring.

Lemon balm
The flowers are tiny but bear all the lemon-cologne flavour of the leaves, so if you find you have lemon balm in bloom you can take the opportunity to use them in ice-cream or to make an exotic floral vinegar. They will add a lemony kick to soft bland salad leaves – think of lemon balm flowers scattered over lamb’s lettuce.

Mint
Mint flowers taste as lovely as the leaves. Use the petals rather than the green stalk and calyxes.
Grow mint in a pot unless you want it to take over the whole garden. Keep different varieties of mint separate or else they will cross and lose their distinctive characteristics. Plants can be propagated by taking softwood cuttings in summer, or by dividing in spring or autumn – small lengths of root will establish quite happily in the soil.

Marjoram/oregano
Marjoram butter is delicious. Oregano flowers can be used to great effect where you would use dried oregano: pizzas and Greek salads spring to mind.
Marjoram and oregano are essentially the same plant even if I do associate one with English country gardens (marjoram) and the other with Mediterranean hillsides (oregano). They grow well in not-so-rich soil and can withstand dry conditions.

Lemon verbena
This is one of my favourite herbs for making herbal tea or adding a cologne-like kick to homemade lemonade. If you have a lemon verbena bush it’s impossible not to rub a leaf or two as you walk past and let the scent waft upwards.
The flowers, which are tiny upright white panicles, are powerfully flavoursome as well – pick out the petals and decorate your sundowner with them, or scatter over lemon sorbet.

Borage
Borage is the classic flower to serve with drinks, either floating on the top or frozen in an ice cube. Certainly the blue flower with the black dot in the centre is very beautiful and the taste is reminiscent of cucumber. I much prefer eating the flowers to the leaves, which also taste faintly of cucumber but which I find a bit too coarse and hairy for my liking. With borage you can keep the stamens but try to remove the green calyx.
It’s an easy plant to grow, an annual which will self-seed freely. So start your borage off by sowing seeds direct in the ground or in a large pot in spring. Growing in a pot will contain the plant but you might well find it self-seeds and springs up elsewhere the next year.

Nasturtiums
Nasturtiums are my garden supercrop. The leaves are great shredded thinly in salads, where they add a pungent peppery kick. The flowers are delicious and look particularly striking on the plate.
The seedheads can be pickled in malt, white or cider vinegar when they look and taste remarkably like capers – they’re known as poor man’s capers, but I think they’re delicious in their own right.
Nasturtiums are ridiculously easy to grow – they’re happiest in a poor soil and they like sun. Sow them in situ in spring once the danger of frost has passed. They look wonderful scrambling through other plants such as beans or peas, or tumbling out of a container.
They will attract insects, both beneficial and pests such as blackfly. Try to wipe the blackfly off before they get a stronghold.

Lavender
I think no English garden is complete without at least one lavender bush. That lovely fragrance that lifts the air as you brush past it – how could anyone bear to live without it? Even better, is a low hedge or border of lavender: clouds of grey-green foliage topped with dusky blue, buzzing with bees all summer long.
The flowers provide an easy and beautiful way to bring the unmistakable lavender fragrance into the kitchen.
Lavender flowers are surprisingly versatile in the kitchen. You can add lavender flowers to an airtight jar of sugar; the resulting infusion makes wonderfully scented desserts like lavender panna cotta, lavender  crème brulee, lavender ice-cream, lavender syrup for pouring … and then there is the possibility of lavender vodka, made by steeping lavender flowers in vodka for several weeks and then straining.
Once you have one lavender plant, it’s easy to propagate by taking softwood cuttings in the summer. I’ve never grown it from seed: it’s always been easy enough to ask for cuttings if I see a variety I particularly like (there must be friends of mine who dread me coming round with a pair of scissors and a plastic bag …).

Squash and courgettes

Squash flowers, stuffed with goat’s cheese or ricotta, dipped in a tempura batter and deep-fried, are always a treat and manage to both taste and look exotic.
Each squash plant will produce both male and female flowers. The male flowers appear first and these will pollinate the later-developing female flowers. You can always tell the difference easily: the female flowers have a courgette or squash fruit developing behind the flower; the male flowers only have the thin green stalk.
If you have a glut of courgettes then a particularly showy starter is to pick a female flower + tiny fruit together and deep-fry them together. Otherwise pick male flowers and save your fruit to use as squash/courgettes on their own. Don’t pick all the male flowers at once though, or your female flowers won’t be pollinated.


Courgettes and squash seeds should be sown indoors in pots: two  seeds to a pot and then the weaker seedling thinned out once they’ve germinated. Once they have true leaves, they’re ready to be moved outside to be hardened off, ie, the plants are allowed to become gradually accustomed to the colder, windier air outside. Then they can be transplanted to the open ground. They like a rich soil so if you have manure or better still fully composted kitchen waste, dig that in before you plant out the squash. They do have a tendency to ramble all over the garden – if you don’t have the space for this, you can train them up a fence or trellis.

If you have a particularly rampant squash plant, nip out the growing tip after it has produced 3-4 fruits, then it can concentrate on growing these fruits to a decent size, instead of lots of little ones at the stem which probably won’t make it to maturity in our season. Courgettes should be picked regularly, otherwise they will grow into giant marrows and the plant will stop growing more courgettes while it’s putting all its energies into the marrow.

Squash should be lifted before the first frost an stored somewhere warm, dry and light to finish ripening before you eat them.
Other flowers
As a general rule, when preparing flowers for eating, remove stamens (the strands in the middle of the flower which carry pollen), and remove the calyx (the often green parts between the petals and the stem),  if large. With some, eg, violas, and rocket and mustard flowers you can eat the whole flowers, but with most you should remove the more indigestible parts.
Hollyhocks (Alcea spp)

The flowers look stunning at the back of a cottage garden border (or anywhere really – once hollyhocks are established, they will happily self-seed all over the place). They also look stunning on the plate. The flowerheads are big enough for you to be able to remove the stamens and green calyx so that you eat just the petals.
Day lilies (Hemerocallis spp)

Most lily flowers are toxic, but Hemerocallis, the day lily, is safe to eat and delicious. You may have seen ‘lily bud’ mentioned on Chinese or Korean restaurant menus and this is what they are, Hemerocallis originating from the Far East. The flowers have a sweet sugary taste, and are often eaten in stir-fries and soups. Their bright orange colour will brighten up a salad as well.
To grow well, they need a sunny spot and moist spot and can also be grown in containers.


Daisies

I can never quite get used to daisies being edible – but they are. I find the petals can be bitter, especially if you use the whole flowerhead,  but they can be stunningly attractive scattered in salads.
It also seems strange to explain how to grow a daisy – most people have them in lawns, as we do in the Secret Garden. This year we’ve also grown some pom-pom daisies here at the edge of the border because daisies are prolific self-seeders and we want to get a greater variety in the lawn. If you do need to grow daisies from scratch, then sow them direct in spring then once established plants can be divided after flowering.

Hibiscus
Hibiscus flowers have a slightly tart flavour. Dried flowers are used to make a mildly astringent tea, however, they can also be ground and mixed with sea salt crystals to make hibiscus salt. This will add a citrusy note to your seasoning and the crimson flakes will look spectacular on your dish as well. Hibiscus flowers are also preserved in syrup and can be served to dramatic effect in champagne and cocktails.
Hibiscus are tropical plants and won’t survive a British winter unless you bring them indoors or protect them. You can propagate by taking cuttings.

Rocket
Rocket is prone to bolting, after which the leaves are rather thin and spindly. Rather than trying to prevent the bolt, you can wait for the inevitable self-seeded plants to spring up and enjoy the baby leaves from these. In the meantime, rocket flowers are surprisingly tasty (surprising because they pack a lot of flavour into a small flower). MsMarmiteLover says the taste reminds her of vanilla. In any case they are excellent for setting off salad leaves and giving the salad a bit of bite. (Don’t pick all the flowers or there won’t be any seeds to scatter around the salad bed!)

Sunflower
Some parts of the sunflower are more edible than others. You can eat the buds whole, rather like a globe artichoke without the fuss of picking bits off. Once the flower has opened, however, only use the petals, which can be eaten raw, or tossed in a stir-fry at the last minute, or stirred into a risotto, maybe. Once the flower has set seed, the seeds can also be eaten, although they need to be shelled first, which can be a slow and nail-breaking experience.
Sunflowers can be sown from seed, either direct into the ground or in pots indoors before planting out. If your ground is at all populated by slugs and snails, then sow indoors and protect the seedlings from slugs by popping a copper ring over them when you plant out. Tall sunflowers may need staking if they grow very big very quickly.

Pelargoniums (scented geraniums)
These pretty pink flowers are edible with a slightly lemony taste, but to be honest the flowers can be more decorative than flavoursome: it’s the leaves that pack the punch for taste. Good with desserts.
Best grown in containers, since they’re not frost-hardy and need to be brought in for winter. Thankfully they do well in pots: place in full sun in late spring and leave outside until the nights become chill in the autumn. Propagate by taking cuttings in spring, or in autumn to overwinter.

Elderflowers
Elderflower cordial is one of my favourite soft drinks but I’m ashamed to say I mostly buy it from Waitrose. The large foamy white elderflower flowerheads are everywhere in May and June and apart from the cordial can be dipped in a tempura-style batter and deep-fried.

Cowslips

Somewhere in the last 150 years we seem to have lost the art of making wine from flowers and hedgerow plants, but cowslip flowers used to be widely used, not just for wine, but in pickles, syrups, to make mead, crystallised, made into cowslip cream.
The mention of mead is a clue to the appeal of cowslips – the flowers have a distinctive honey aroma and taste. Pull them away from the calyx and if you don’t feel like making wine or mead, use them in salads or in the vinaigrette. Don’t feel too bad about the wine-making: you need around 1litre of cowslip flowers for 1litre of wine.

Primroses
Primroses were used to make sweets in Victorian times. Crystallised primroses are beautifully decorative, but Kathy Brown in her beautiful book Edible Flowers suggests making a spring ice bowl with primrose flowers, violets and cowslips, which I think sounds heavenly, and just the thing for serving ice-cream and sorbets.
Primroses like a bit of shade and are often one of the first winter flowers and always welcome on a cold wet day. Once established the plants will self-seed. 

Violets (Viola spp)

Viola flowers are made for crystallising or for scattering over a salad to turn something mundane into something very special. Many varieties are sold in the UK as bedding plants – pansies, violas, sweet violets, all can be used in the kitchen.
They can be sown from seed, but their ubiquity as bedding plants mean you might as well buy plants and keep them going.




Pot Marigold (Calendula spp)
This is Calendula, rather than Tagetes, the French or African marigold. Calendula is used in cosmetics, especially creams, and has edible flowers.
Calendula is a hardy annual and once established should self-seed in your garden. The flowerheads are much larger than those of French or African marigolds and the petals taste slightly spicy. Pull them off individually and use to make marigold butter, or in puddings or bread for an elusive flavour and a beautiful yellow-orange colour – the visual effect is similar to adding saffron.
Calendula was used extensively in cooking in the olden days – in stews, soups and preserves. You can still buy large quantities of dried marigolds in markets in the Middle East (especially in Turkey) where it is used as a saffron substitute.

Poisonous flowers
Having said that many flowers are edible while many more are either tasteless or have an unpleasant texture, there are also some flowers which are actively poisonous.
It’s not just that they don’t taste nice, they would actually cause you harm. Plant toxins can be very powerful – even in The Secret Garden there are some plants that could kill you.
Plants of the nightshade family are obvious examples. We don’t have any deadly nightshade here, but we do have other members of the family:

  • Potatoes, tomatoes, and the Chilean potato vine (Solanum crispum): In all cases the flowers are poisonous, as are the leaves and stems. Tomato fruits are edible of course, but it’s worth knowing that the similar fruit produced by potatoes are also toxic.
  • Sweet peas (Lathyrus odorata): just because other types of pea are edible, don't assume that they all are.
  • Foxgloves
  • Peppers (Capsicum annuum): both sweet peppers and chilli peppers have inedible flowers, despite having edible fruits.
  • Hydrangeas
It's worth knowing also about other flowers that are poisonous. These don't grow in the Secret Garden but are widely found elsewhere: 



  • Asparagus: you can only eat the immature stems and buds.
  • Datura, or Angels' trumpets: a popular patio plant with a heady fragrance. The whole plant is poisonous. 
  • Horse chestnut.
  • Some aquilegias (columbines).
  • Lily of the valley.
  • Most lilies, as mentioned above.
  • Oleander.
  • Rhododendrons
  • Zantedeschia (calla lily)
  • Delphiniums
  • Autumn crocuses
And note that this is not a exhaustive list.
Don't let that put you off. Edible flowers can add an extra dimension to a meal – they can complement the other ingredients, eg, basil flowers with tomatoes, a citrus flower on lemon drizzle cake. They can add a different flavour, a different texture to something otherwise familiar and give it a touch of the exotic. And this high impact comes for very little extra outlay, if you have a garden with the flowers growing in it.

5 things to remember about using edible flowers
  1. Make sure you know what plant you’re eating – grow it yourself or have it clearly identified.
  2. If you suffer from hay fever or any other kind of pollen allergy, be very cautious indeed.
  3. Remove dirt and insects.
  4. Use the flowers as fresh as possible.
  5. Don’t pick all the flowers from one plant.
