Allium vineale (Wild Garlic, Crow Garlic or stag's garlic) is a perennial bulbflower in the genus Allium, native to Europe, northwestern Africa (Algeria, Morocco and the Canary Islands) and southwestern Asia (Turkey, Lebanon, Syria, Azerbaijan, Armenia, etc.). The species was introduced in Australia and North America, where it has become an invasive species. The species is widespread across the eastern United States and the lower Mississippi Valley, and has also been recorded in California, Washington, Oregon, British Columbia, Ontario, Quebec, Tasmania, Victoria, New South Wales, South Australia, and Western Australia.
All parts of the plant have a strong garlic odour. 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 tubes, 15-60 cm long and 2-4 mm thick, waxy texture, with a groove along the side of the leaf facing the stem. The inflorescence is a globular cluster surrounded by a membranous bract in bud which withers when the flowers open. Each individual flower is stalked and has a pinkish-green perianth 2.5 to 4.5 mm (0.10 to 0.18 in) long. There are six tepals, six stamens and a pistil formed from three fused carpels. Mixed with the flowers are several of yellowish-brown bulbils. The fruit is a capsule but the seeds seldom set and propagation usually takes place when the bulbils are knocked off and grow into new plants. Plants with no flowers, only bulbils, are sometimes distinguished as the variety Allium vineale var. compactum, but this character is probably not taxonomically significant.
Uses and problems
While Allium vineale has been suggested as a substitute for garlic, there is some difference of opinion as to whether there is an unpleasant aftertaste compared to that of garlic itself. It imparts a garlic-like flavour and odour on dairy and beef products when grazed by livestock. It is considered a pestilential invasive weed, as grain products may become tainted with a garlic odour or flavour in the presence of aerial bulblets at the time of harvest. Wild garlic is resistant to herbicides due to the structure of its leaves, being vertical, smooth and waxy. Herbicides do not cling well to it and are therefore not as effective.
