Phyllostachys iridescens is one of our largest, fastest growing, and strongest bamboos. The culm walls are very thick and are used for timber. Many of the canes have light yellow striping and a bright white band beneath the node. Some also have graceful bends in the lower internodes. The culm sheaths when the new shoots emerge are a very attractive reddish-brown, with long, colorful sheath blades (see photo on left). This bamboo makes a nice specimen or grove and is very cold hardy and reliable.
