Allium vineale (wild garlic, onion grass, crow garlic or stag's garlic) is a perennial, bulb-forming species of wild onion, native to Europe, northwestern Africa and the Middle East. The species was introduced in Australia and North America, where it has become a noxious weed.
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 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.
