Шаблон:Short description Шаблон:Speciesbox Allium oleraceum, the field garlic, is a Eurasian species of wild onion. It is a bulbous perennial that grows wild in dry places, reaching Шаблон:Convert in height. It reproduces by seed, bulbs and by the production of small bulblets in the flower head (similarly to Allium vineale). Unlike A. vineale, it is very rare with A. oleraceum to find flower-heads containing bulbils only.[1] In addition, the spathe in A. oleraceum is in two parts.[1][2]

Its specific epithet oleraceum means "vegetable/herbal" in Latin and is a form of Шаблон:Wikt-lang (Шаблон:Lang).[3][4]

Description

Allium oleraceum grows to a height of about Шаблон:Convert. The underground bulb is up to Шаблон:Convert in diameter. The main stem is usually rounded, but is occasionally flattened, and bears two to four leaves and a terminal inflorescence composed of a number of small, stalked, pinkish-brown flowers and sometimes a few bulblets. The papery bracts have long points which often much overtop the flowers, the stamens of which do not protrude.[5]

Distribution

Allium oleraceum is widespread across most of Europe, with additional populations in Turkey and the Caucasus.[6][7] It is sparingly naturalised in scattered locations in North America.[8][9][10]

In the United Kingdom, A. oleraceum is found in dry, grassy places, usually steeply sloping and calcareous soils, and on open sunny banks in river floodplains. A. oleraceum is scattered throughout England and very scattered in Wales, Scotland and Ireland.[11]Шаблон:Rp Erosion of coastal areas leads to a reduction in the available habitat for this species, leading to population declines.[12] The highest altitude from which it has been recorded in Britain is Шаблон:Convert in Dovedale, Derbyshire.[13]

Allium oleraceum subsp. girerdii was formerly included, but is now classified as Allium oporinanthum.[7]
