Allium triquetrum

Onion Weed

New Zealand Status: Introduced
Conservation Status: n/a

Allium triquetrum is a perennial herb with fleshy grass-like leaves and small, white, bell-shaped flowers that have green mid-veins. It grows in clumps to about 60cm high. The leaves and stalks are triangular in section and have a distinct onion smell when crushed. Onion weed can be found in disturbed forest and shrub land, stream sides, herb fields and bare land. It is a persistent and troublesome weed forming dense colonies.

Many parts of the plant are edible and can be used in salads or as a flavouring in cooked foods. The leaves have a mild onion flavour while the flowers and bulbs have a mild garlic flavour.

May be toxic if eaten in large quantities, dogs being particularly susceptible. If eaten by cows the milk will be tainted.
