Bamboo is a tribe of flowering perennial evergreen plants in the grass family Poaceae, subfamily Bambusoideae, tribe Bambuseae. Bamboos are some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. In fact, within a 24 hour period, bamboo can grow four feet. Bamboo is used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel.
