Why Wild Garlic Is Worth Knowing

By late March, the damp floor of a British deciduous wood starts to smell faintly of garlic before you have even spotted a leaf. That scent belongs to wild garlic, Allium ursinum, known in many parts of the country as ramsons. It carpets the ground under beech, ash and oak in cool, slightly acid soils, often alongside bluebells and wood anemones, and it is one of the surest signs that you are standing in an ancient woodland that has been continuously wooded for centuries.

For the forager it is a generous plant: mild, green and versatile, somewhere between chives and spring greens in flavour. For wildlife it matters just as much. Its early flowers feed queen bumblebees, hoverflies and solitary bees at a time of year when little else is open, and its bulbs are dug up and eaten by badgers and deer. That double value is why it deserves to be gathered thoughtfully rather than stripped bare.

Telling It Apart From Its Dangerous Lookalikes

Wild garlic is not a plant to guess at. Its leaves emerge in spring, before the flowers, and several poisonous woodland plants push up similar foliage at the same moment. The good news is that identification is straightforward if you slow down and check more than one feature.

• Scent: the single most reliable test. Tear or crush a single leaf and you will get an unmistakable hit of garlic. If there is no smell, walk away.
• Leaves: long, broad and lance-shaped, soft rather than leathery, usually a slightly glossy medium green, and growing in a loose rosette from the base of the plant rather than in pairs up a stem.
• Flowers: star-shaped white flowers on a single stem, appearing from April, with a garlicky scent of their own.

The plants most often confused with it are lily of the valley, whose leaves rise in pairs from a single stalk and which is seriously poisonous; lords-and-ladies, also called cuckoo pint, whose young arrow-shaped leaves are toxic; and the spring leaves of meadow saffron, which are long and strappy and highly poisonous. None of these smell of garlic when crushed. If you are in any doubt at all, leave it, and take a single leaf home to check with a good field guide before you pick in quantity.

Where and When to Look

Wild garlic likes damp, shaded ground: the banks of streams and ditches, the lower slopes of wooded valleys, and the deep leaf litter beneath mature trees. It often grows in broad drifts, so once you find a patch you will usually find plenty of it. Old hedgerows and churchyards can hold small colonies too.

Pick leaves from late March until the flowers open in earnest. After flowering the leaves turn bitter and begin to die back, so the window is short. Choose clean leaves well above the soil, avoiding anything that has been walked over, fouled by dogs or splashed by muddy tracks.

Picking Kindly, and Staying Within the Rules

In England and Wales, the Wildlife and Countryside Act 1981 allows you to pick the leaves, flowers and fruit of wild plants for personal use, but uprooting any wild plant without the landowner's permission is an offence. Scotland has similar protection. That means leaves only, never bulbs, and never a plant lifted from the ground. Many nature reserves, Sites of Special Scientific Interest and land managed by conservation charities prohibit foraging altogether, so check before you set out and respect any signs you meet.

Beyond the law, there is a simple etiquette that keeps a patch healthy for years:

• Take a little from many plants rather than everything from a few — one or two leaves from each, never stripping a plant bare.
• Leave the flowers alone. They are the plant's future, and the bees' spring larder.
• Snap leaves off cleanly at the base with your fingers; do not tug, which can loosen the bulb.
• Stay on paths where you can. Woodland floor plants, bluebell bulbs included, are easily crushed underfoot.
• Carry a basket or cotton bag. Wild garlic sweats and slimes in a plastic bag within an hour.

In the Kitchen and in the Garden

Use wild garlic quickly. The leaves lose their punch within a day or two of picking, so wash them, dry them gently and either cook them straight away or blitz them into pesto with nuts, hard cheese and olive oil. They are lovely stirred through soup at the last moment, folded into butter, chopped into potato salad or wilted under a poached egg. The flower buds, picked sparingly, make a pretty, peppery garnish.

If you have a damp, shady corner at home, wild garlic grows happily from seed or from bulbs bought from a reputable nursery — please do not dig them from the wild. Give it leaf mould, dappled shade and room to spread, and within a few springs you will have your own patch, feeding the bees and filling the kitchen in equal measure.
