Distribution

It is a temperate plant. It grows in grasslands in forest area between 2300-2400 m in China. It is frost hardy.

Where It Grows

Asia, China, Himalayas, India, Myanmar, Nepal, SE Asia, Tibet,

Propagation

Seed - best sown as soon as it is ripe in a shady position in a cold frame. Stored seed remains viable for at least a year and can be sown in spring in the greenhouse but it will probably require a period of cold stratification. Germination usually takes place in 1 - 6 months at 15°c. When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the greenhouse for at least a coupe of years until the corms are more than 20mm in diameter. Plant out into their permanent positions whilst they are dormant. Division of tubers when the plant dies down in late summer.

Other Uses
