The Water feature planters are designed in non-porous polyethylene to hold water. The water gardening containers are the Illaria Planters, Montana Bowls, Orinoco Bowls and Bird Baths. With a broad selection of shapes, depths and sizes, these containers can accommodate a variety of water gardening plants and fish. Some of our planters are also equipped for use with water pumps such as the our large Orinoco Bowls. The rest of the Crescent planters are of a different polyethylene composite which is porous in nature to allow breathing. These planters will not hold water and saucers are suggested for interior use.The logo WG is identified through out the catalogue.
