Cork bark is harvested from the Cork Oak Tree (Quercus Suber). This process does not harm the tree in any way. The trees can be reharvested time-and-again for their entire lifespan, up to 20 years. Therefore, cork as a product is one of the most renewable and environmentally friendly products found anywhere in the world.
Virgin Cork Bark is bark that comes from the first or second harvest of the cork tree. This bark is distinguished by it's gnarly and burled surface texture. It is often used in terrariums or vivariums and hides and enclosures, as a mounting or growing substrate for orchids, tillandsia air plants, and various bromeliads.
