Bamboo flooring is made from the fast growing bamboo grass and can be harvested in 4 or 5 years. Bamboo can regenerate without seeding and is often grown without pesticides. As a flooring material bamboo is durable and dense, and wears as well as maple and oak. The natural density reduces the need to refinish as often as hardwood. Milled like hardwood, with a tongue and groove on all four sides, bamboo is easy to install.
