About Allium nigrum L.
Allium nigrum L. produces asymmetric bulbs that can grow up to 5 cm across. Each individual plant grows 3 to 6 lanceolate, flat leaves that bend to the side, reaching up to 60 cm long and 2.5 cm across; mature leaves become reflexed. Its scapes are smooth, round in cross-section, and grow 80 to 100 cm tall. The scape bears a dense umbellate inflorescence made up of star-like flowers, each up to 9 mm across. The flower tepals are white with a green midvein, and the anthers are purple or yellow. During anthesis, the ovaries are black-green, though plants growing in the Levant have red-tinged ovaries; younger ovaries and those that have passed anthesis are green. This species is commonly grown as an ornamental plant in European and North American gardens, and was introduced to these regions in the early twentieth century. It is cultivated in Taean and Seosan, South Korea.
