Acidosasa guangxiensiss is an evergreen bamboo that can grow around 2 - 3 metres tall; the erect, woody culms are around 10 - 20mm in diameter with thin-walled internodes that are 16 - 18cm 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.

Acidosasa species are native from low to moderate elevations in the moist subtropical regions of southeast China. Whilst many of them experience occasional light to moderate frosts in their native environment, none of them are very cold-tolerant. They can generally be grown outdoors in areas with very mild winters and with at least moderate levels of rainfall.
Bamboos generally grow best in a sunny or moderately sunny position in a well-drained, fertile, open loam of reasonable quality with plenty of moisture in the growing season[
]. They require a position sheltered from cold or strong winds[
Bamboos have an interesting method of growth. Each plant produces a number of new stems annually -usually in the spring and early summer, and these stems grow to their maximum height in their first two to three months. Any subsequent growth in the stem is limited to the production of new side branches and leaves.
Temperate bamboo species usually grow for many years without flowering. When they do finally flower it is not unusual for all the plants of that species in the region to also flower. They do so profusely over a period of 1 - 3 years and will often then die, probably from exhaustion. Some species, if given plenty of organic matter at this time will gradually recover, although they will look rather poorly for a year or three. If fed with artificial NPK fertilizers at this time the plants are more likely to die[
Bamboo species are usually notably resistant to honey fungus[
The stems are used for making broom handles and fences[
Seed - if possible, surface sow the seed as soon as it is ripe in a greenhouse at about 20°c. Stored seed should be sown as soon as it is received. 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. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a lightly shaded place in the greenhouse or cold frame until they are large enough to plant out, which could be a number of years. The plants only flower at intervals of several years and so seed is rarely available.
Division in spring as new growth commences. 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[
Basal cane cuttings.
