Allium is a genus with around 1000 species, making it one of the largest plant genera in the world. [1] [2]
The number of accepted species in the genus Allium varies depending on the source, but as of November 2024, World Flora Online accepts 969 species, [3] while Plants of the World Online accepts 1077 species: [2]
Scallions are edible vegetables of various species in the genus Allium. Scallions generally have a milder taste than most onions. Their close relatives include garlic, shallots, leeks, chives, and Chinese onions. The leaves are eaten both raw and cooked.
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.
Gagea is a large genus of spring flowers in the lily family. It is found primarily in Eurasia with a few species extending into North Africa and one species in North America.
Bellevalia is a genus of plants in the family Asparagaceae, subfamily Scilloideae. It was first described as a genus in 1808.
Hedysarum (sweetvetch) is a genus of the botanical family Fabaceae, consisting of about 200 species of annual or perennial herbs found in Asia, Europe, North Africa, and North America.
Allium nigrum, common name black garlic, broad-leaved leek, or broadleaf garlic, is a Middle Eastern species of wild onion. It lacks the onion or garlic scent shared by most of the other species in the group. The species is native to Turkey, Cyprus, Syria, Lebanon, and Israel but cultivated as an ornamental in many other places. It has become naturalized in some regions, including parts of the United States.
The Koninklijke Algemeene Vereniging voor Bloembollencultuur, translated from Dutch as the Royal General Association for Bulb Culture, but more commonly known world-wide by the acronym of KAVB, is a trade association for the bulb horticulture sector, and was established in 1860. The association has a rural organization, within which regional groups and departments are active.
Jurinea is a genus of flowering plants in the family Asteraceae.
Allium filidens is a species of onion found at high elevations of central and south-central Asia. It is a bulb-forming perennial up to 45 cm tall, forming a hemispherical umbel of flowers; tepals white or pink with a purple midvein.
Allium akaka is a species of onion native to Iran.
Allium is a large genus of monocotyledonous flowering plants in the family Amaryllidaceae. Many of the species are edible, and some have a long history of cultivation and human consumption as a vegetable including the onion, garlic, scallions, shallots, leeks, and chives. The onion is the vegetable crop produced in the second largest quantities worldwide, after tomatoes. The genus Allium has about 1000 accepted species, making it amongst the largest plant genera in the world. It is by far the largest genus in the Amaryllidaceae plant family, and also in the Alliaceae in classification systems in which that family is recognized as separate.
The precise taxonomy of the genus Allium is still poorly understood with incorrect descriptions being widespread. With over 850 species distributed over the Northern hemisphere Allium is the sole genus in the Allieae, one of four tribes of subfamily Allioideae (Amaryllidaceae). New species continue to be described and Allium is both highly variable and one of the largest monocotyledonous genera, but the precise taxonomy of Allium is poorly understood, with incorrect descriptions being widespread. The difficulties arise from the fact that the genus displays considerable polymorphism and has adapted to a wide variety of habitats. Furthermore, traditional classications had been based on homoplasious characteristics. However, the genus has been shown to be monophyletic, containing three major clades, although some proposed subgenera are not. Some progress is being made using molecular phylogenetic methods, and the internal transcribed spacer (ITS) region, including the 5.8S rDNA and the two spacers ITS1 and ITS2, is one of the more commonly used markers in the study of the differentiation of the Allium species.
