Allium atrosanguineum is an Asian species of onion native to China, Siberia, Mongolia, and Central Asia. It grows high in the mountains at elevations of 2400–5400 m.[3][4]
Allium atrosanguineum produces cylindrical bulbs up to 10 mm in diameter. Scapes are round in cross-section, up to 60 cm tall. Leaves are round in cross-section, usually shorter than the scapes. Umbels appear spherical from a distance, with many flowers. Tepals are pink, yellow, copper-colored, brass-colored or purple, sometimes with small dark spots.[3][5]
Three varieties are generally recognized:[2][3]
- Allium atrosanguineum var. atrosanguineum—Tepals purple - red with small spots — western China (Qinghai, Sichuan, Xinjiang), Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, Afghanistan), Pakistan, Siberia (Tuva, Buryatiya, Krasnoyarsk, Zabaykalsky Krai), Mongolia
- Allium atrosanguineum var. fedschenkoanum (Regel) G.H.Zhu & Turland[6] - tepals pale yellow or pink — Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, Afghanistan), Pakistan, Tibet, Xinjiang
- Allium atrosanguineum var. tibeticum (Regel) G.H.Zhu & Turland[6] — tepals copper-colored or brass-colored — Western China (Tibet, Gansu, Qinghai, Sichuan, Yunnan)
