Allium triquetrum, also known as three cornered garlic or three cornered leek is coming through now. All parts of this plant are edible, its leaves, flowers and bulbs. It has a garlicy onion flavour and can be used anywhere you would use things like garlic chives or spring onions. No need to cook it, it can be eaten raw. Careful picking in public places as its a declared weed and will most likely be sprayed. In a few weeks it will be more obvious when its white flowers come through. This was growing along a creek.
