Allium tuberosum Rottler ex Sprengel - Amaryllidaceae - garlic chives, Chinese chives, nira, Knoblauch-Schnittlauch

Widely cultivated as a vegetable, it is native in Shanxi Province, China, at altitudes 1000-1100 meters.

„The flavor is more like garlic than chives. It grows in slowly expanding perennial clumps, but also readily sprouts from seed. In warmer areas, garlic chives may remain green all year round. In cold climates, aerial parts of garlic chives will die back completely to the ground and the roots/rhizomes will over-winter and then re-sprout in spring time.“ https://en.wikipedia.org/wiki/Allium_tuberosum

„Allium tuberosum is generally regarded as a cultivated species with a tetraploid chromosome number (2 n = 32), although a wild population was recently discovered in Shanxi Province with a diploid number (2 n = 16; Yang et al., Acta Phytotax. Sin. 36: 36–46. 1998).“ http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200027544

„The flavor components of Nira (Allium tuberosum Rottl.) have been studied by a combination of gas chromatography and mass-spectrometry. Twenty-nine compounds were identified in the oil obtained from extraction of the steam distillate of Nira. The identified compounds include 7 sulfides, 2 ketones, 18 alcohols and 2 esters. The main volatile components were dimethyl disulfide and dimethyl trisulfide.“
