Onion-like above the ground this plant is all about its underground bulb which provides the basis of most Indian, Thai, Italian and French cuisine - amongst others.
It is extremely pungent and good for warding off vampires as well as close freinds.
The bulb is papery externally and above ground it produces delicate pinky white flowers on a short stalk in summer.
Its also very good to plant near roses to keep aphids away.
