Phyllostachys species (Bamboo)
Phyllostachys is a genus of bamboo which includes approximately 75 species and 200 varieties and cultivars. The species are native to Asia with a large number of species found in Central China. Most of them spread aggressively by underground rhizomes. They are a tall, clump-forming evergreen bamboos with the stem or culm which has a prominent groove, called a sulcus, that runs along the length of each segment (or internode). Because of this Phyllostachys are one of the most easily identifiable genera of bamboo. They usually have two leafy branches at some nodes. Some species have green culm which turns yellow in full or partial sun, and deepen into a gold-orange colour as the plant matures.
This species of Phyllostachys have a culm diameter of up to 12 cm.
