Nothoscordum gracile syn. N. inodorum
Onion weed is a perennial with thin green strappy leaves growing from a mainly white bulb which gives off an onion smell when crushed. Flowers grow at the top of a long stalk and are mainly white. Seeds form in summer and autumn and are spread mostly by wind blowing the seeds into new areas. Onion weed also develops small bulblets attached to the parent bulb. These sprout even after the main parent bulb has died from herbicide application or simply from breaking off from the parent bulb when being pulled up. Repeat applications onto the weed will most likely be required.
