Designed to live outdoors in exposed conditions, the Ridge Planter is molded from fiberglass-reinforced concrete mixed with stone, mother-of-pearl and shell. Ground shell and stone break the surface as a fine speckle, so the body has some life in it when the sun hits. The body is frost resistant and drains from an open hole in the base, the two things that decide whether a planter can be left outdoors year-round. Set a pair at either side of a door, or use one to anchor the corner of a patio.
