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. [2] The species was introduced in Australia and North America, where it has become an Invasive species. [3] [4] [5] [6] [7]
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 (flower) 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. Although very similar with the leaves of Allium schoenoprasum (Chives), they tend to be more fibreous, have more vertical grooves, and the grooves are better defined than the leaves of chives.
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 (3⁄32 to 3⁄16 in) long. There are six tepals, six stamens and a pistil formed from three fused carpels. Mixed with the flowers are several 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. [8] [9]
Plants with no flowers, only bulbils, are sometimes distinguished as the variety Allium vineale var. compactum, but this character is probably not taxonomically significant.[ citation needed ]
Although crow's garlic has an odour similar to true garlic, A. sativum, forms flowers full of bulbils just like garlic and dies back during summer, the leaf structure is more similar to those of chives, A. schoenoprasum, to which A. vineale is more closely related to than true garlic.
During summer, just like domesticated garlic (A. sativum), after it forms the flower, the plant dies back over the course of the last summer months and sprouts back in mid autumn when precipitations grow and temperatures drop enough.
This is one of the reasons why the plants can be quite easily spread and become a weed, because during the most intense agricultural soil mechanical interactions, the weeds are almost impossible to identify, and both the bulbs and newly formed bulbils are dormant and less susceptible to die from mechanical damage. [10]
The leaves, flowers, and bulbs of Allium vineale are edible. [11] While it 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 ( Allium sativum ).[ 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 in the US, as grain products may become tainted with a garlic odour or flavour in the presence of aerial bulblets at the time of harvest. [12] [13] [14] Wild garlic is tolerant to herbicides, which cannot cling well to the vertical, smooth and waxy structure of its leaves. [15] [16]
Allium vineale 'Hair', a cultivated variety, is sold as an ornamental plant in the UK and USA. It has unusual flowerheads which have purple centres and green hair-like extensions. [17] [18]
Chives, scientific name Allium schoenoprasum, is a species of flowering plant in the family Amaryllidaceae that produces edible leaves and flowers.
Garlic is a species of bulbous flowering plant in the genus Allium. Its close relatives include the onion, shallot, leek, chive, Welsh onion, and Chinese onion. It is native to Central Asia, South Asia and northeastern Iran and has long been used as a seasoning worldwide, with a history of several thousand years of human consumption and use. It was known to ancient Egyptians and has been used as both a food flavoring and a traditional medicine. China produced 73% of the world's supply of garlic in 2021.
An onion, also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus Allium. The shallot is a botanical variety of the onion which was classified as a separate species until 2011. Its close relatives include garlic, scallion, leek, and chive.
In botany, a bulb is a short underground stem with fleshy leaves or leaf bases that function as food storage organs during dormancy. In gardening, plants with other kinds of storage organ are also called ornamental bulbous plants or just bulbs.
Allium ursinum, known as wild garlic, ramsons, cowleekes, cows's leek, cowleek, buckrams, broad-leaved garlic, wood garlic, bear leek, Eurasian wild garlic or bear's garlic, is a bulbous perennial flowering plant in the amaryllis family Amaryllidaceae. It is native to Europe and Asia, where it grows in moist woodland. It is a wild relative of onion and garlic, all belonging to the same genus, Allium. There are two recognized subspecies: A. ursinum subsp. ursinum and A. ursinum subsp. ucrainicum.
Allium oleraceum, the field garlic, is a Eurasian species of wild onion. It is a bulbous perennial that grows wild in dry places, reaching 30 centimetres (12 in) in height. It reproduces by seed, bulbs and by the production of small bulblets in the flower head. Unlike A. vineale, it is very rare with A. oleraceum to find flower-heads containing bulbils only. In addition, the spathe in A. oleraceum is in two parts.
Allium tuberosum is a species of plant native to the Chinese province of Shanxi, and cultivated and naturalized elsewhere in Asia and around the world. It has a number of uses in Asian cuisine.
The tree onion is a perennial plant similar to the common onion (A. cepa), but with a cluster of bulblets where a normal onion would have flowers. Tree onions are also known as topsetting onions, walking onions, or Egyptian onions. Genomic evidence has conclusively shown that they are a diploid hybrid of the shallot and the Welsh onion (A. fistulosum). However, some sources may still treat the tree onion as A. cepa var. proliferum or A. cepa Proliferum Group.
Allium canadense, the Canada onion, Canadian garlic, wild garlic, meadow garlic and wild onion is a perennial plant native to eastern North America from Texas to Florida to New Brunswick to Montana. The species is also cultivated in other regions as an ornamental and as a garden culinary herb. The plant is also reportedly naturalized in Cuba.
Allium ampeloprasum is a member of the onion genus Allium. The wild plant is commonly known as wild leek or broadleaf wild leek. Its native range is southern Europe to southwestern Asia and North Africa, but it is cultivated in many other places and has become naturalized in many countries.
The sand leek, also known as rocambole and Korean pickled-peel garlic, is a Eurasian species of wild onion with a native range extending across much of Europe, Middle East, and Korea. The species should not be confused with rocambole garlic, which is A. sativum var. ophioscorodon.
Allium sphaerocephalon is a plant species in the Amaryllis family known as round-headed leek, round-headed garlic, ball-head onion, and other variations on these names. Drumstick allium is another common name applied to this species. Some publications use the alternate spelling Allium sphaerocephalum. It is a bulbous herbaceous perennial plant.
Allium neapolitanum is a bulbous herbaceous perennial plant in the onion subfamily within the Amaryllis family. Common names include Neapolitan garlic, Naples garlic, daffodil garlic, false garlic, flowering onion, Naples onion, Guernsey star-of-Bethlehem, star, white garlic, and wood garlic.
Allium monanthum, the Korean wild chive, is a spring vegetable with minuscule bulbous roots that have a mild onion flavor and found in the woodlands of Korea, Japan, northeastern Russia (Primorye), and northeastern China.
A bulbil is a small, young plant that is reproduced vegetatively from axillary buds on the parent plant's stem or in place of a flower on an inflorescence. These young plants are clones of the parent plant that produced them—they have identical genetic material. The formation of bulbils is a form of asexual reproduction, as they can eventually go on to form new stand-alone plants.
Allium triquetrum is a bulbous flowering plant in the genus Allium native to the Mediterranean basin. It is known in English as three-cornered leek or three-cornered garlic, in Australia as angled onion and in New Zealand as onion weed. Both the English name and the specific epithet triquetrum refer to the three-cornered shape of the flower stalks.
Allium paradoxum, the few-flowered garlic or few-flowered leek, is an Asian species of wild onion in the Amaryllis family. It is native to mountainous regions of Iran, Caucasus, and Turkmenistan and invasive in Europe.
Allium macrostemon, Chinese garlic, Japanese garlic or long-stamen onion, is a species of wild onion widespread across much of East Asia. It is known from many parts of China, as well as Japan, Korea, Mongolia, Tibet and Primorye. It has been collected from elevations ranging from sea level to 3000 m.
Allium rhynchogynum is a Chinese species of wild onion endemic to the Yunnan region in southern China. It grows at elevations of 2700–3200 m.
Allium is a genus of monocotyledonous flowering plants with hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. It is one of about 57 genera of flowering plants with more than 500 species. It is by far the largest genus in the Amaryllidaceae, and also in the Alliaceae in classification systems in which that family is recognized as separate.
The leaves, flowers, and bulbs are edible and can be used similarly to chives, although they tend to be a bit tougher.
