Cultivation Details

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[].

Edible Uses

Root - cooked[].

Seed[]. 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[].

Medicinal

One report says that the plant has been used for medicinal purposes in Kashmir, but gives no further details[].

Other Uses

The leaves of most species in this genus can be used to make a soft, insulated bedding for sleeping on when camping etc[].

Propagation

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.
