Allium vineale (Crow Garlic or Wild Onion) is a
perennial bulbflower in the genus
Allium, native to
Europe, north
Africa and western
Asia. The species is introduced in
Australia and
North America, where it has become an
invasive species.All parts of the plant have a strong
garlic odor. The underground
bulb is 1-2 cm diameter, with a fibrous outer layer. The main
stem grows to 30-120 cm tall, bearing 2-4
leaves and an apical
inflorescence 2-5 cm diameter comprising a number of small bulbils and none to a few
flowers, subtended by a basal
bract. The leaves are slender hollow
tubular, 15-60 cm long and 2-4 mm thick, waxy textured, with a groove along the side of the leaf facing the stem. The flowers are 2-5 mm long, with six petals varying in colour from pink to red or greenish-white. It flowers in the summer, June to August in northern Europe. Plants with no flowers, only bulbils, are sometimes distinguished as the
variety Allium vineale var. compactum, but this character is probably not
taxonomically significant.
