Sin. 36: 36-46. 1998)." [[http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200027544|efloras.org]]
-"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."

 "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." \\

 In the headspace of A. tuberosum, diallyl disulphide was detected as the main component (58%). \\
