Bamboos are a group of woody perennial evergreen plants in the grass family Poaceae, subfamily Bambusoideae. Bamboos are the fastest growing woody plants in the world. Their growth rate (up to 60 centimeters (24 in.)/day without chemical pesticides) is due to a unique rhizome-dependent system, but is highly dependent on local soil and climate conditions.
