Allium flavum (yellow) and Allium carinatum (purple)

Allium is a genus of monocotyledonous flowering plants that includes hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. The generic name Allium is the Latin word for garlic,[4][5] and the type species for the genus is Allium sativum which means "cultivated garlic".[6]

Linnaeus first described the genus Allium in 1753. Some sources refer to Greek αλεω (aleo, to avoid) by reason of the smell of garlic.[7] Various Allium have been cultivated from the earliest times, and about a dozen species are economically important as crops, or garden vegetables, and an increasing number of species are important as ornamental plants.[7][8]

The decision to include a species in the genus Allium is taxonomically difficult, and species boundaries are unclear. Estimates of the number of species are as low as 260,[9] and as high as 979.[10]

Allium species occur in temperate climates of the Northern Hemisphere, except for a few species occurring in Chile (such as A. juncifolium), Brazil (A. sellovianum), and tropical Africa (A. spathaceum). They vary in height between 5 cm and 150 cm. The flowers form an umbel at the top of a leafless stalk. The bulbs vary in size between species, from small (around 2–3 mm in diameter) to rather large (8–10 cm). Some species (such as Welsh onion A. fistulosum) develop thickened leaf-bases rather than forming bulbs as such.

Plants of the genus Allium produce chemical compounds, mostly derived from cysteine sulfoxides, that give them a characteristic onion, or garlic, taste and odor.[7] Many are used as food plants, though not all members of the genus are equally flavorful. In most cases, both bulb and leaves are edible. The cooking and consumption of parts of the plants is due to the large variety of textures, and flavours, which may be strong or weak, that they can impart to the dish they are used in. The characteristic Allium flavor depends on the sulfate content of the soil the plant grows in.[7] In the rare occurrence of sulfur-free growth conditions, all Allium species completely lose their usual pungency.

In the APG III classification system, Allium is placed in the family Amaryllidaceae, subfamily Allioideae (formerly the family Alliaceae).[11] In some of the older classification systems, Allium was placed in Liliaceae.[7][8][12][13][14] Molecular phylogenetic studies have shown this circumscription of Liliaceae is not monophyletic.

Allium is one of about fifty-seven genera of flowering plants with more than 500 species.[15] 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.[9]


Capsule of Allium oreophilum.

The genus Allium (alliums) is characterised by herbaceous geophyte perennials with true bulbs, some of which are borne on rhizomes and an onion or garlic odor and flavor.[16]

The bulbs are solitary or clustered and tunicate and the plants are perennialized by the bulbs reforming annually from the base of the old bulbs, or are produced on the ends of rhizomes or, in a few species, at the ends of stolons. A small number of species have tuberous roots. The bulbs' outer coats are commonly brown or grey, with a smooth texture, and are fibrous, or with cellular reticulation. The inner coats of the bulbs are membranous.

Many alliums have basal leaves that commonly wither away from the tips downward before or while the plants flower, but some species have persistent foliage. Plants produce from one to 12 leaves, most species having linear, channeled or flat leaf blades. The leaf blades are straight or variously coiled, but some species have broad leaves, including A. victorialis and A. tricoccum. The leaves are sessile, and very rarely narrowed into a petiole.

The flowers, which are produced on scapes are erect or in some species pendent, having six petal-like tepals produced in two whorls. The flowers have one style and six epipetalous stamens; the anthers and pollen can vary in color depending on the species. The ovaries are superior, and three-lobed with three locules.

The fruits are capsules that open longitudinally along the capsule wall between the partitions of the locule.[17][18] The seeds are black, and have a rounded shape.

The terete or flattened flowering scapes are normally persistent. The inflorescences are umbels, in which the outside flowers bloom first and flowering progresses to the inside. Some species produce bulbils within the umbels, and in some species, such as Allium paradoxum, the bulbils replace some or all the flowers. The umbels are subtended by noticeable spathe bracts, which are commonly fused and normally have around three veins.

Some bulbous alliums increase by forming little bulbs or "offsets" around the old one, as well as by seed. Several species can form many bulbils in the flowerhead; in the so-called "tree onion" or Egyptian onion (A. × proliferum) the bulbils are few, but large enough to be pickled.

Many of the species of Allium have been used as food items throughout their ranges. There are several poisonous species that are somewhat similar in appearance (e.g. in North America, death camas, Toxicoscordion venenosum), but none of these has the distinctive scent of onions or garlic.[19][20]


With over 850 species[21] Allium is the sole genus in the Allieae, one of four tribes of subfamily Allioideae (Amaryllidaceae). New species continue to be described[21] and Allium is one of the largest monocotyledonous genera,[22] but the precise taxonomy of Allium is poorly understood,[22][21] 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 (the independent evolution of similar features in species of different lineages). However, the genus has been shown to be monophyletic, containing three major clades, although some proposed subgenera are not.[22] 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.[21]

Allium includes a number of taxonomic groupings previously considered separate genera (Caloscordum Herb., Milula Prain and Nectaroscordum Lindl.) Allium spicatum had been treated by many authors as Milula spicata, the only species in the monospecific genus Milula. In 2000, it was shown to be embedded in Allium.[23]

When Linnaeus[2] formerly described the genus Allium in his Species Plantarum (1753), there were thirty species with this name. He placed Allium in a grouping he referred to as Hexandria monogynia (i.e. six stamens and one pistil)[24] containing 51 genera in all.[25]


Linnaeus originally grouped his 30 species into three alliances, e.g. Foliis caulinis planis. Since then, many attempts have been made to divide the growing number of recognised species into infrageneric subgroupings, initially as sections, and then as subgenera further divided into sections. For a brief history, see Li et al. (2010)[22] The modern era of phylogenetic analysis dates to 1996.[26] In 2006 Friesen, Fritsch, and Blattner[27] described a new classification with 15 subgenera, 56 sections, and about 780 species based on the nuclear ribosomal gene internal transcribed spacers. Some of the subgenera correspond to the once separate genera (Caloscordum, Milula, Nectaroscordum) included in the Gilliesieae.[22][28] The terminology has varied with some authors subdividing subgenera into Sections and others Alliances. The term Alliance has also been used for subgroupings within species, e.g. Allium nigrum, and for subsections.[29]

Subsequent molecular phylogenetic studies have shown the 2006 classification is a considerable improvement over previous classifications, but some of its subgenera and sections are probably not monophyletic. Meanwhile, the number of new species continued to increase, reaching 800 by 2009, and the pace of discovery has not decreased. Detailed studies have focused on a number of subgenera, including Amerallium. Amerallium is strongly supported as monophyletic.[30] Subgenus Melanocrommyum has also been the subject of considerable study (see below), while work on subgenus Allium has focussed on section Allium, including Allium ampeloprasum, although sampling was not sufficient to test the monophyly of the section.[31]

The major evolutionary lineages or lines correspond to the three major clades. Line one (the oldest) with three subgenera is predominantly bulbous, the second, with five subgenera and the third with seven subgenera contain both bulbous and rhizomatous taxa.[22]

Evolutionary lines and subgenera

The three evolutionary lineages and 15 subgenera represent the classification scheme of Friesen et al. (2006)[27] and Li (2010).[22] (number of sections/number of species)

Cladogram of evolutionary lines in Allium[27]

First evolutionary line

Second evolutionary line

Third evolutionary line

First evolutionary line

Although this lineage consists of three subgenera, nearly all the species are attributed to subgenus Amerallium, the third largest subgenus of Allium. The lineage is considered to represent the most ancient line within Allium, and to be the only lineage that is purely bulbous, the other two having both bulbous and rhizomatous taxa. Within the lineage Amerallium is a sister group to the other two subgenera (Microscordum+Nectaroscordum).[22]

Second evolutionary line

Nearly all the species in this lineage of five subgenera are accounted for by subgenus Melanocrommyum, which is most closely associated with subgenera Vvedenskya and Porphyroprason, phylogenetically. These three genera are late-branching whereas the remaining two subgenera, Caloscordum and Anguinum, are early branching.[22]

Third evolutionary line

The third evolutionary line contains the most number of sections (seven) and also the largest subgenus of the genus Allium, subgenus Allium which includes the type species of the genus, Allium sativum. This subgenus also contains the majority of the species in the line. Within the lineage the phylogeny is complex. Two small subgenera Butomissa and Cyathophora form a sister clade to the remaining five subgenera, with Butomissa as the first branching group. Amongst the remaining five subgenera, Rhizirideum forms a medium-sized subgenus that is the sister to the other four larger subgenera. However, they may not be monophyletic.[22]

Distribution and habitat

The majority of Allium species are native to the Northern Hemisphere, being spread throughout the holarctic region, from dry subtropics to the boreal zone,[22] but predominantly in Asia. Of the latter 138 species occur in China, about a sixth of all species, representing five subgenera.[22] A few species are native to Africa and Central and South America.[17] A single known exception, Allium dregeanum occurs in the Southern Hemisphere (South Africa). There are two centres of diversity, a major one from the Mediterranean Basin to Central Asia and Pakistan, while a minor one is found in western North America.[22] The genus is especially diverse in the eastern Mediterranean.[32]


Species grow in various conditions from dry, well-drained mineral-based soils to moist, organic soils; most grow in sunny locations, but a number also grow in forests (e.g., A. ursinum),[7] or even in swamps or water.[citation needed]

Various Allium species are used as food plants by the larvae of the leek moth and onion fly[7] as well as some Lepidoptera including cabbage moth, common swift moth (recorded on garlic), garden dart moth, large yellow underwing moth, nutmeg moth, setaceous Hebrew character moth, turnip moth and Schinia rosea, a moth that feeds exclusively on Allium species.[citation needed]


Selection of cultivated alliums displayed at the BBC Gardeners' World Live show

Many Allium species have been harvested through human history, but only about a dozen are still economically important today as crops or garden vegetables.[7][33]


Many Allium species and hybrids are cultivated as ornamentals.[34] These include A. cristophii and A. giganteum, which are used as border plants for their ornamental flowers, and their "architectural" qualities.[8][35] Several hybrids have been bred, or selected, with rich purple flowers. A. hollandicum 'Purple Sensation' is one of the most popular and has been given an Award of Garden Merit (H4).[36] These ornamental onions produce spherical umbels on single stalks in spring and summer, in a wide variety of sizes and colours, ranging from white (Allium 'Mont Blanc'), blue (A. caeruleum), to yellow (A. flavum) and purple (A. giganteum). By contrast, other species (such as invasive A. triquetrum and A. ursinum) can become troublesome garden weeds.[35][37]

The following cultivars, of uncertain or mixed parentage, have gained the Royal Horticultural Society’s Award of Garden Merit:

  • ’Ambassador’[38]
  • ’Beau Regard’[39]
  • ’Gladiator’[40]
  • ’Globemaster’[41]
  • ’Round and Purple’[42]


Dogs and cats are very susceptible to poisoning after the consumption of certain species.[7][43]


The genus includes many economically important species. These include onions (A. cepa), French shallots (A. oschaninii), leeks (A. ampeloprasum), scallions (various Allium species), and herbs such as garlic (A. sativum) and chives (A. schoenoprasum). Some have been used as traditional medicines.[22]
