The Clifornia Redwood Co.'s planter boxes include darker accent pieces that are reclaimed pieces of redwood previously used for separating wood stacks in the kiln. Before now, the pieces could not be used for other purposes. All the products are made with ecologically grown wood certified by the Forest Stewardship Council. Three different models are available with 6-in. by 6-in. copper panels for an elegant, artful look.
