Bamboo is a giant grass noted for the usefulness of its hollow woody stem. Scientists rank bamboos among the most primitive of grasses. Most of these plants grow naturally in tropical climates or in the warm regions of temperate climates.
Most bamboos are of giant size.
Some may stand as much as 37 metres high and have stems 30 cm in diameter. The structure of the bamboo plant body may be arbitrarily considered as two main portions, an underground part of the stem, called the rhizome, and an above ground portion of the stem, called the culm. Hence, bamboo usually grow from new shoots that sprout from the base of the mature plant. Bamboos rarely bloom. Some have blossoms only once every 30 years.
