Bamboo

Bamboo is a group of grasses in the family Poaceae, not a type of tree. There are more than 1,600 described species, found naturally in many parts of Asia, Africa and the Americas. Most bamboos have woody, hollow stems called culms, which grow from underground stems known as rhizomes. Depending on the species, the rhizomes may spread outward and produce new shoots or form tighter clumps.

Bamboo can grow rapidly under suitable conditions, although growth rates vary greatly among species and environments. Its leaves are usually narrow, and new culms emerge from buds near the base of older ones. Some species flower only after many years, and flowering may occur across large populations at roughly the same time. Bamboo has both ecological and practical importance.

Dense stands provide shelter and food for animals, help protect soil from erosion and store carbon as they grow. In some ecosystems, however, spreading bamboo can compete strongly with other plants. Humans have cultivated bamboo for thousands of years. Its strong, flexible stems are used for construction, furniture, tools, paper, musical instruments and many everyday objects.

Young shoots of certain species are also eaten as food after appropriate preparation. Because bamboo regenerates from its underground stems, some species can be harvested repeatedly without replanting each individual stem. Its usefulness therefore comes from a combination of rapid growth, strong fibres and the ability of many species to regrow after cutting.
