This green culmed timber bamboo is thought to be the true species from which ‘Black Bamboo’ originated. In the Pacific Northwest it is one of the largest bamboos. There are mature stands that reach a height of 50 feet with a culm diameter of nearly 4 inches. The wood of this species has greater density and strength than most other timber bamboo except P. bambusoides. It may be much hardier than 0° F, possibly hardy to -10° F. The culms age to an distinct olive grey color; some call it as “Giant Grey Bamboo”. It’s vigorous growth, feather-like leaf pattern, and upright habit, make 'Henon’ one of the finest choices for a true bamboo forest.
