Allium polyrhizum explained

Allium polyrhizum is a species of wild onion widespread across Zabaykalsky Krai, Kazakhstan, Mongolia, and China (Gansu, Hebei, Heilongjiang, Jilin, Liaoning, Inner Mongolia, Ningxia, Qinghai, Shaanxi, Shanxi and Xinjiang) at elevations 1000–3700 m.^{[1] [2] [3] [4] [5]}

Allium polyrhizum produces clumps of many narrowly cylindrical bulbs, each generally less than 10 cm in diameter. Scape is up to 30 cm long, round in cross-section. Leaves are tubular, less than 1 cm across, shorter than the scape. Umbel is hemispheric with many densely packed flowers. Tepals are usually pink or purple but occasionally white, either way with a green midvein.^{[1] [6] [7]}
