Description and General Information:
This dwarf Allium is native to alpine slopes and subalpine forest margins of the Chinese Himalayas at an elevation of 2100-5000 m. Very narrow, grass-like leaves arise from small bulbs. Leaves are typically around 15 cm long. The flowers are held atop 10-30 cm stems and bloom from August to October in its native region. The nodding to outward-facing flowers are bell to star-like, powdery-blue to deep cobalt blue. The stamens and style are exerted, a feature that will help distinguish it from the similar A. beesianum and A. sikkimense.
This dwarf Allium is ideal for a trough or crevice garden but also suitable for the open rockery. Provide full sun and a well drained but not droughty soil. It is not particular about the soil pH.
July to September
Mainly by seed; division of larger clumps.
Sow seeds in pots and leave outside for the winter as seeds need a stratification period of 8-12 weeks. Otherwise place in refrigerator for required stratification time.
Larger clumps may be dug and divided in early spring or early autumn.
