Each of these beautifully hand carved stone planters are one of a kind. Each is carved from a single block of stone. The serene, earthy look has no comparison. Cantera stone planters are mineral rich and porous, helping to feed and modulate the humidity of the plants they contain. Unlike clay and ceramics, Cantera is resistant to breakage from freezing weather. Each planter comes with drainage holes in the base. Cantera stone is lighter in color when dry, and when wet it darkens and colors intensify.
