Yushania emeryi is a clump-forming, evergreen bamboo that can possibly grow up to 10 metres tall with erect, woody culms up to 45mm in diamete[
]. The plant spreads slowly by means of short rhizomes, eventually forming quite a large, dense clump.
The plant is harvested from the wild for local use as a source of materials.

Yushania emeryi is found at elevations up to 3,200 metres in the Himalayas of Nepal, where it experiences frost and snow.
Prefers an open loam of fair quality[
] and a position sheltered from cold drying winds[
]. Succeeds on peaty soils. Requires abundant moisture and plenty of organic matter in the soil[
]. Grows well in light woodland[
The plant forms a moderately tight clump in the wild and thus does not hinder the regeneration of forests in its native range since the tree seedlings are able to germinate and re-produce in the gaps between the clumps[
This species is notably resistant to honey fungus[
Bamboos have an interesting method of growth. Each plant produces a number of new stems annually - these stems grow to their maximum height in their first year of growth, subsequent growth in the stem being limited to the production of new side branches and leaves. In the case of some mature tropical species the new stem could be as much as 30 metres tall, with daily increases in height of 30cm or more during their peak growth time. This makes them some of the fastest-growing species in the world[
Bamboos in general are usually monocarpic, living for many years before flowering, then flowering and seeding profusely for a period of 1 - 3 years before usually dying. This pattern can vary - sometimes flowering is sporadic, with plants flowering annually and not dying; at other times it is gregarious with all the plants in a specific species coming into flower at the same time.
The canes have level nodes, thin walls and long internodes. They split easily and are suitable for weaving into baskets etc[
Seed - surface sow as soon as it is ripe in a greenhouse at about 20°c. Do not allow the compost to dry out. Germination usually takes place fairly quickly so long as the seed is of good quality, though it can take 3 - 6 months. Grow on in a lightly shaded place in the greenhouse until large enough to plant out. Seed is rarely available.
Division in late spring[
]. Best done as the new shoots first appear above ground[
]. Take divisions with at least three canes in the clump, trying to cause as little root disturbance to the main plant as possible. Grow them on in light shade in a greenhouse in pots of a high fertility sandy medium. Mist the foliage regularly until plants are established. Plant them out into their permanent positions when a good root system has developed, which can take a year or more[
