Bamboo is one of the fastest-growing plants in the world. Bamboo looks like wood, feels like wood, and cuts like wood. It even smells like wood. But bamboo isn’t wood at all—it’s grass. And it’s much thicker than most hardwoods, so it’s ideal for flooring. Bamboo can be collected after just four or five years. By contrast, it typically takes between 30 and 60 years before hardwood trees can be milled into flooring. Plus, bamboo regenerates after cutting, and the same plant can be harvested again just four or five years later.
