Three cornered leek, Allium triquetrum
The bulb can be eaten raw or cooked. The rather small bulb is up to 20mm in diameter, it has a mild garlic flavour and can be used as a flavouring in salads and cooked foods. It is harvested in early summer when the plant has died down and will store for at least 6 months.
Leaves are edible raw or cooked. A leek substitute. The leaves are available from late autumn until the spring, they are nice in salads when they are young, or cooked as a vegetable or flavouring as they get older. The leaves have a milder and more delicate flavour than onions.
Flowers can be used raw. Juicy with a mild garlic flavour, they make a tasty and decorative garnish on salads.
Although no specific mention of medicinal uses has been seen for this species, members of this genus are in general very healthy additions to the diet. They contain sulphur compounds (which give them their onion flavour) and when added to the diet on a regular basis they help reduce blood cholesterol levels, act as a tonic to the digestive system and also tonify the circulatory system.
The juice of the plant is used as a moth repellent.
The whole plant is said to repel insects and moles.
