Hachiku Bamboo Plant

Henon bamboo (*Phyllostachys nigra* 'Henon') is a vigorous evergreen running bamboo with tall green canes and glossy, narrow foliage. It forms a large grove; its rhizomes need room and active containment. ## Form and size The [Royal Horticultural Society profile](https://www.rhs.org.uk/plants/78374/phyllostachys-nigra-f-henonis/details) lists *Phyllostachys nigra* 'Henon' as a synonym of *P. nigra* f. henonis and describes young canes that become brownish-yellow with age. The [University of Georgia Extension](https://fieldreport.caes.uga.edu/publications/B1357/growing-bamboo-in-georgia/) lists Henon as a running bamboo reaching up to 65 feet, while an exact [plant listing](https://www.bamboogarden.com/bamboo/phyllostachys-nigra-henon) gives a 40-foot average and 60-foot maximum in USDA Zones 7–10. Sources describe mature culms in shades from brownish-yellow to olive-gray or whitish-green. The RHS profile gives a smaller 2.5–4 metre height and spread; mature size varies with climate and growing conditions. ## Growing conditions The RHS recommends full sun or partial shade and moist, well-drained loam. Keep soil moisture steady while avoiding waterlogging, especially as a young planting establishes. Henon retains green canes as they mature, distinguishing it from black bamboo. ## Maintenance University of Georgia Extension’s [running bamboo guidance](https://fieldreport.caes.uga.edu/publications/B1357/growing-bamboo-in-georgia/) recommends a correctly installed root barrier to contain bamboo. Check the barrier and grove edges regularly, and thin weak or crowded culms in spring. This is a large, spreading bamboo for a site where its eventual grove can be managed safely.
