Phyllostachys vivax

Chinese Timber Bamboo

Max/Avg Height (ft.): 70, 40-50

Diameter: 3-5 inches

Hardiness: -5° F

USDA Zones: 6-10

Phyllostachys vivax is one of the hardiest timber bamboo. In most circumstances P. vivax will mature to 45 feet in height, with 3-4 inch diameter canes, but if given ideal conditions in SE USA, or China and Japan, it can grow to 70 feet and 5 inches in diameter. This may be the largest hardy bamboo growing in the Pacific Northwest along with P. edulis Moso. It has grown over 4 inches in diameter in Oregon and has been present in this area for over 100 years. It is usually the quickest to attain large size in the PNW. Even though they have a large diameter, the culms have a thinner wall than average thus are not especially strong. They are very attractive and can be used for many craft or decorative projects, but not recommended for building grade material. Shoots from this bamboo are among the best eating, and they are prolific in the late spring.  Often the new shoots emerge in mid to late May, depending on the weather pattern which influences the soil temperature. Even though this bamboo is very large, it can still be contained using the basic root pruning techniques we recommend. Unlike most bamboos, P. vivax can achieve large size and diameter in a relatively small area, as seen on the 2nd and 3rd images.  This bamboo is over 30 feet tall and is growing on a raised berm that is less than 30 feet in circumference.  A miniature grove has formed a very effective vertical screen.
