Growth—

Phyllostachys flexuosa is a very hardy plant, tolerating temperatures down to about -17°c. According to another report the plant only suffers minor leaf damage at -22°c[1]. It dislikes prolonged exposure to hard frosts[2]. Succeeds in full sun and in partial shade. Requires a rich damp soil in a sheltered position[2] and plenty of moisture in the growing season[3]. This species is notably resistant to honey fungus[2]. A plant at Trebah gardens in Cornwall, England was flowering heavily in May 1995[PFAF]. New growth appears from late March[4]. This species is closely related to Phyllostachys angusta[5]. Plants need quite a lot of space because the outer culms spread out sideways and arch over[6]. 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[PFAF]. 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.

Propagation

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[7]. Division is best carried out in wet weather and small divisions will establish better than large clumps[7]. 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[2]. Basal cane cuttings in spring. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Phyllostachys+flexuosa>
