Did you know that bamboo and cork floors are becoming more popular choices because of their resemblance to traditional hardwood floors. The main problem with traditional hard woods — like pine, maple, and oak — is that those forests take decades to regrow. Oak can take up to 120 years to fully mature. But bamboo and cork are fast growing: Bamboo (which is actually grass) generally regenerates in about four to six years, and cork plants regrow in about nine years.
