Allium paradoxum
A small woodland allium that carpets shaded ground from late winter, spreading by bulbils rather than by seed. Each bulb sends up a single narrow, keeled, grass-like leaf and a bluntly three-angled stem, topped by a nodding umbel that usually carries just one white bell alongside a cluster of green bulbils. Leaves, flowers and bulbils all smell and taste of mild garlic and are used like chives or wild garlic.
Naturalised in Britain and Ireland from the Caucasus and northern Iran, most abundant around Edinburgh and the Scottish central belt. Forms dense carpets on damp, shaded ground — river banks, churchyards, hedge banks and roadside woodland — often crowding out native ground flora.
Leaves, flowers and bulbils are all edible, though the sulphur compounds behind the garlic flavour can upset the stomach if a lot is eaten raw. Crush a leaf and check for the garlic smell before picking anything from a woodland carpet. It spreads aggressively and is listed on Schedule 9 of the Wildlife and Countryside Act 1981 in Scotland, so bulbs and bulbils should never be moved to new ground.
Always use more than one reference to confirm a plant. You are responsible for what you choose to forage.
Growth habit
Forms continuous, dense carpets of grass-like foliage in shade, often to the exclusion of everything else. Spread is by bulbils dropped at the flower head and by bulb division, so colonies are uniform in age and height rather than patchy.
Leaf
A single leaf per bulb (occasionally two), flat, keeled beneath and roughly 10–25 mm wide, bright green above and greyer below. That solitary narrow leaf separates it from Wild Garlic, whose broad ovate leaves rise on clear stalks.
Flower head
A papery spathe opens to a nodding umbel of usually one white bell, sometimes up to five, mixed with a tight cluster of pea-sized green bulbils. Three-cornered leek carries 3–15 bells, each with a green midline stripe, and no bulbils in the head.
Stem section
Rolling the stem between finger and thumb gives a bluntly three-angled feel rather than a round one, but it is not the sharply keeled, sharply triangular stem of three-cornered leek.
Smell
A crushed leaf smells clearly of garlic or chives. If there is no allium smell at all, put it down — every part of this plant carries the scent, and an unscented spring leaf from the same woodland floor is a different species.
