Bamboo

Bamboo is a grass, and a fast-growing one at that. It can grow from a tiny sprout to being ready to harvest in just three to five years, which makes it a very eco-friendly flooring option. And fast turnaround isn't the only great thing about this tall shoot. Bamboo is also fire-resistant, comes in easy-to-install planks and is 27 percent harder than Northern red oak and 13 percent harder than hard maple. Image courtesy of US Floors
