Bamboo is a group of woody perennial evergreen plants in the true grass family Poaceae, subfamily Bambusoideae, tribe Bambuseae. Some of its members are giant bamboo, forming by far the largest members of the grass family. Bamboo is the fastest growing woody plant in the world. Their growth rate (up to 15 cm -1 m/day) is due to a unique rhizome-dependent system, but is highly dependent on local soil and climate conditions. They are of economic and high cultural significance in East Asia and South- East Asia where they are used extensively in gardens, as a building material, and as a food source.

There are 91 genera and about 1,000 species of bamboo. There are 150 or 600 species (depending on researcher) in Japan.
