Pottery for depends on the houseplant. For plants which like to be drier at the root, such as: palms, citrus, succulents, and cacti, use an unglazed terracotta pot. For houseplants, like our many tropicals, which enjoy a moister condition at the root, think about glazed ceramic or plastic. If you are growing African Violets, bonsai, or orchids, we have specialty pots just for them.
