Allium cyaneum
Allium cyaneum, dark blue garlic, is a Chinese species of onion. It prefers to grow at elevations from on slopes and meadows, and forest edges. It occurs in Gansu, Hubei, Ningxia, Qinghai, Shaanxi, Sichuan and Xizang provinces of China, and possibly in Korea. Its leaves and scapes are edible and are occasionally consumed by local peoples as a spice after drying. It has gained the Royal Horticultural Society's Award of Garden Merit, and is also considered by them as a good plant to attract pollinators.
