Pilea mollis is a species of flowering plant in the family Urticaceae. It is used as an ornamental plant, particularly the cultivar 'Moon Valley'.
Pilea is a genus consisting of about 600 species of frost tender, tropical foliage plants that include both upright bushy types and trailing varieties. Several smaller species are commonly cultivated as houseplants because they are so easy to grow and care for. These inexpensive little plants are excellent for growing indoors in dish gardens and are great starter plants for young or inexperienced growers. Their foliage varies considerably, ranging from 3" strongly textured, lance-shaped leaves to tiny heart-shaped, moss-like foliage. Pileas occasionally bloom, but their pink or cream-colored flowers are very tiny and often go unnoticed.
