Carex nubigena is a perennial plant growing from a rhizomatous rootstock. The rhizome is short, producing a dense clump of grass-like leaves around 10 - 70cm tall[
The plant is harvested from the wild for local use as a food and medicine
E. Asia - Pakistan, India, Sri Lanka, Nepal, Bhutan, southern and central China, Japan, Vietnam, Philippines, Indonesia (Java)
Streamsides, forest margins and roadsides on slopes, grassy slopes, wet places; at elevations from 1,100 - 3,700 metres[
Carex nubigena has a wide native range, from Ningxia in China (hardiness zone 6) to the highland tropics of the Philippines and Indonesia
Easily grown in a damp to wet soil in full sun or shade[
Members of this genus are rarely if ever troubled by browsing deer[
Root - cooked[
]. No further details are given, but the seed is small and fiddly to use[
We have no more specific information for this species, but the young shoots and tender leaf bases of almost all species in this genus have a sweet flavour[
]. They furnish a tasty nibble and make an excellent emergency food in the wild since they are widely available[
One report says that the plant has been used for medicinal purposes in Kashmir, but gives no further details[
The leaves of most species in this genus can be used to make a soft, insulated bedding for sleeping on when camping etc[
Seed - sow in situ in the spring in a moist soil in light shade. If seed is in short supply it can be sown in a cold frame and be planted out in the summer. The seed usually germinates in 2 - 6 weeks at 15°c[
]. Species in this genus, when started from seed tend to stay diminutive for over a year, with plant leaves remaining stunted and fragile for a considerable period of time[
Division in spring[
]. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the summer or following spring.
