Wikipedia
Allium is a genus of monocotyledonous flowering plants that includes the cultivated onion, garlic, scallion, shallot and leek as well as chives and hundreds of other wild species.
The generic name Allium is the Latin word for garlic, and Linnaeus first described the genus Allium in 1753. Some sources refer to Greek αλεω (aleo, to avoid) by reason of the smell of garlic. The cooking and consumption of parts of the plants is due to the large variety of flavours and textures of the species. 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. The inclusion of a species to the genus Allium is taxonomically difficult and species boundaries are unclear. Estimates of the number of species have been as low as 260, and as high as 979. Most authorities accept about 750 species. The type species for the genus is Allium sativum.
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 Allium genus produce chemical compounds (mostly derived from cysteine sulfoxides) that give them a characteristic (alliaceous) onion or garlic taste and odor. Many are used as food plants, though not all members of the genus are equally flavorous. In most cases, both bulb and leaves are edible and the taste may be strong or weak, depending on the species and on ground sulfur (usually as sulfate) content. In the rare occurrence of sulfur-free growth conditions, all Allium species lose their usual pungency altogether.
In the APG III classification system, Allium is placed in the family Amaryllidaceae, subfamily Allioideae (formerly the family Alliaceae). In some of the older classification systems, Allium was placed in Liliaceae. 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. 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.

Claudia pictured a pond, a double row of neatly clipped yew hedges bisecting her immaculate new lawn and framing the kind of borders that would be filled with a profusion of traditional perennials like delphiniums, poppies, alliums and lupins.
No trace is left of their former abrupt curvature, excepting in the case of Allium cepa, in which the cotyledon rarely becomes quite straight, owing to the protuberance developed on the crown of the arch.
