Description from Flora of China
Allium ascalonicum Linnaeus var. chinense Kunth.
Bulb ovoid-globose to ovoid; tunic red-brown to yellowish brown, scarious, entire. Leaves deep green, narrower than those of Allium cepa and A. fistulosum, terete, fistulose. Scape usually not developed (plants propagated by bulbs), if developed then fistulose, inflated. Spathe 2- or 3(or 4)-valved. Umbel globose. Pedicels slender, longer than perianth. Perianth white; segments with green midvein, oblong, apex obtuse, sometimes with reflexed point. Filaments subulate, subequal, ca. 2 × as long as perianth segments. 2 n = 16.
Allium cepiforme originated in cultivation, probably as a result of hybridization between A. cepa and A. fistulosum.
Cultivated. Mostly in E China, also Xinjiang [widely cultivated elsewhere].
