Three-cornered garlic – a non-native flower
Grows on roadside banks and woodland
Allium triquetrum, is known as three-cornered garlic. I recognise it by comparison with ransoms – it is slightly taller than Allium ursinum with narrower leaves but still has the characteristic garlic scent, and flowers at about the same time. The clusters of white nodding flowers are borne on a long stem with triangular cross-section, giving its name. It is common in woodland, but plants local to me are on a shady bank by the side of the road.
These alliums are an invasive introduction from the Mediterranean. They are edible and can be treated like spring onion once identified correctly.
