Common Name: Ringal
Yushania anceps is an evergreen bamboo that can grow around 4.5 metres tall; the erect, woody culms are around 12mm in diameter with thin-walled internodes around 10 - 28cm long[
]. The rhizomes are elongated, the plant having a running habit that can produce new canes some distance from the main clump, especially in warm climates
The plant is harvested from the wild for local use as a source of materials. Very ornamental, it can be grown as a hedge or screen in gardens.

Yushania anceps is found at elevations up to 3,000 metres in the Himalayas, where it experiences frost and snow. Reports on hardiness vary, some saying it cannot tolerate much frost, others that it can tolerate occasional short-lived temperatures falling as low as -20Â°c. It often loses its leaves in severe winters in southern Britain, though usually recovers[
]. It is unlikely to withstand prolonged periods of cold weather.
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[
New shoots are produced from late spring[
The rhizome is running and can be invasive[
]. It is fairly easy to control, however, because the new shoots are brittle and easily broken off of the plant.
In a well-managed stand of the plant, yields of around 14 tonnes per hectare per year of canes can be obtained[
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.
This species often flowers in Britain, sometimes continuously over a number of years. Although individual stems may die, the plant is not monocarpic and often produces viable seed[
]. Plants can be badly weakened by flowering but they usually recover, however they are likely to be killed if they are given artificial NPK fertilizers at this time[
The plant makes an attractive hedge or screen, eventually becoming very dense[
When split, the canes are used for weaving mats.baskets etc[
]. The canes are also used as plant supports, though they must be properly ripened[
Seed - surface sow as soon as it is ripe in a greenhouse at about 20Â°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 the seedlings are large enough to plant out, which could take a few years. 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[
