Onion weed

Onion weed (Allium triquetrum) - also known as three-cornered garlic - is a weed recognisable by its slender, light green grass-like leaves and snowdrop-like flowers. The plant has a distinctive onion fragrance when crushed. The flower stems appear from the middle of the leaves in spring and early summer producing clusters of pure white drooping flowers that open above the foliage. The flower stems themselves are characteristically three-cornered. Every part of this plant is edible and it can be treated a bit like a spring onion or baby leek. Onion weed grows from a small parent bulb and spreads underground by producing additional tiny bulbils that grow into dense crowded clumps of foliage
