Description

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 tight umbel surrounded by a membranous bract in bud which withers when the flowers open. Each individual flower is stalked and has a pinkish-green perianth Template:Convert 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.<ref name=NatureGate>Template:Cite web</ref><ref>Template:Cite book</ref> 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 common garlic (A. sativum).Template:Citation needed 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.<ref>Eric Block, "Garlic and Other Alliums: The Lore and the Science" (Cambridge: Royal Society of Chemistry, 2010)</ref><ref>James L. Brewster, "Onions and Other Alliums" (Wallingford: CABI Publishing, 2008)</ref><ref>Dilys Davies, "Alliums: The Ornamental Onions" (Portland: Timber Press, 1992)</ref> Wild garlic is resistant to herbicides, which cannot cling well to the vertical, smooth and waxy structure of its leaves. Herbicides do not cling well to it and are therefore not as effective.<ref>Wild Garlic & Wild Onion. Clemson University. Retrieved May 12, 2013</ref><ref>Template:Cite book</ref>
