Phyllostachys nigra henonis Ha-chiku Evergreen bamboo (1 Page of 5) The Phyllostachys nigra henonis plant species is found in E. Asia - E. and C. China, Japan. It is a member of the Gramineae family. Common gardeners may know the plant as Ha-chiku. Some home gardeners know the variety as P. henonis. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Phyllostachys nigra henonis Common Name: Ha-chiku Family: Gramineae Author: (Mitford.)Stapf. Known Hazards: None known Mature Height: 6 Mature Width: Habitat: Fertile and moist places, also by streams[147].
Cultivation Notes: Requires a rich damp soil in a sheltered position[200] and plenty of moisture in the growing season[1].
A very hardy plant, tolerating temperatures down to at least -7°c, but it dislikes prolonged exposure to hard frosts[200]. Another report says that it tolerates temperatures down to about -20°c[195].
A very ornamental plant[1], this is the form of P. nigra that is most commonly met in the wild. It is believed that this form is the true wild form and that the species is in fact a garden cultivar. However, since that form was the first to be named botanical etiquette demands that this form is treated taxonomically as a cultivar[195]. It is this form 'Henonis' that is used medicinally in China[176].
Plants only flower at intervals of many years. When they do come into flower most of the plants energies are directed into producing seed and consequently the plant is severely weakened. They sometimes die after flowering, but if left alone they will usually recover though they will look very poorly for a few years. If fed with artificial NPK fertilizers at this time the plants are more likely to die[122].
This is a good companion species to grow in a woodland because the plants are shallow rooted and do not compete with deep rooted trees[195].
This species is notably resistant to honey fungus[200].
The plant has a running rootstock, though not agressively so in the cooler climate of Britain[200]. and it produces new shoots from May[25].
Dead stems can be removed at any time of the year[238]. It is also possible to thin the clumps in spring, leaving only the strongest stems and thus creating an open grove-like effect[238].
Cultivated for its edible young shoots in China[61]. This species has been widely planted for ornament in the Mediterranean and is becoming established[50].
