Lyptus lumber comes from sustainable, plantation-grown hybrid eucalyptus trees. The trees are grown in Brazil and may be harvested within 14 to 16 years of being planted. It is a durable hardwood, slightly harder than red oak, with a grain pattern similar to mahogany. The natural color varies from salmon to a reddish brown. It darkens slightly with exposure to UV rays and is a durable outdoor wood if properly finished with exterior products. Available at rockler.com.
