Bamboos are a group of woody perennial evergreen plants in the true grass family Poaceae. Some of its members are giants, forming by far the largest members of the grass family. There are 91 genera and about 1,000 species of bamboo. They are found in diverse climates, from cold mountains to hot tropical regions.

The woody ringed stems, known as culms, are typically hollow between the rings (nodes) and grow in branching clusters from a thick rhizome (underground stem). Bamboo culms can attain heights ranging from 10 to 15 cm (about 4 to 6 inches) in the smallest species to more than 40 metres (about 130 feet) in the largest.
