Phyllostachys mannii is an evergreen bamboo that can grow 8 - 12 metres tall; the erect, woody culms are 40 - 60mm in diameter with thin-walled internodes 30 - 42cm 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. This tendency to run, however, is somewhat curtailed in cooler climates, where new shoot production can be rather reduced.
The plant is harvested from the wild for use as a source of materials. It is cultivated in central and southern China for this purpose[
E. Asia - Himalayan regions of India and Myanmar.

Phyllostachys mannii is native to the subtropical regions of the Indian and Myanmar Himalayas, but is also often cultivated in the temperate to warm temperate regions of southern China.
Succeeds in full sun and in partial shade. Species in this genus generally tolerate a wide range of soils and sites, though they prefer a damp humus-rich soil in sun or semi-shade[
]. They grow best in a position sheltered from cold winds[
]. Plants are generally not very tolerant of dry conditions[
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 is a good companion species to grow in a woodland because the plants have shallow root systems that do not compete with deep tree roots[
The stems are split and used for weaving mats and various articles[
]. The unsplit stems are used for making walking sticks[
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 spring as new growth commences. Divisions from the open ground do not transplant well, so will need careful treatment and nurturing under cover in pots until at least late spring[
]. Division is best carried out in wet weather and small divisions will establish better than large clumps[
]. Another report says that you can take large divisions from established clumps and transfer them straight to their permanent positions, misting or drenching them frequently until they are established[
