Onion Weed

16 Dec, 2021

Allium Triquetum. Also known in some English speaking countries as Three Cornered Leek.

This attractive weed is a member of the onion, garlic and leek family (allium). It grows from bulbs and has grass like leaves and clumps of white bell shaped flowers. Leaves, stems, and bulbs have a light garlicy onion scent. All parts of the plant are edible.


For most of the year the bulbs stay dormant, but through winter and spring they burst into life and form a dense mat that can make growing other plants difficult.

Physical Control

Pull or dig out plants and bulbs regularly. Over time this will eventually eradicate the problem. However make sure that you dispose of bulbs carefully. Don’t add to your compost as this will spread the problem around.
