Phyllostachys vivax, commonly known as Chinese Timber Bamboo, is an evergreen bamboo species that exhibits a rapid growth rate, reaching heights of over 8 meters (26 feet) with the potential to grow up to 21 meters (69 feet) according to some sources. It has strong, green canes that can measure up to 12 centimeters (4.7 inches) in diameter. As the canes mature, they transition to a yellow color, and the plant is characterized by its drooping leaves. This bamboo is native to China, where it thrives in forest margins and along riverbanks. It forms clumps initially, but given time, it can establish expansive thickets through its underground running rhizomes unless growth is contained.

Chinese Timber Bamboo is valued for its rapid growth and the visual impact of its large canes, making it suitable for use as a visual screen or as a feature plant in parks and large gardens. It is hardy down to at least −15 °C (5 °F). Cultivation requires consideration of its potential invasiveness; barriers can be installed to restrict rhizome spread. It prefers full sun to part shade and requires moist, well-drained soil. While it is relatively low-maintenance, occasional thinning is necessary to manage its spread and maintain its aesthetic appeal.CC BY-SA 4.0
