Callisia, commonly called Inch Plant, is a trailing plant with striking leaves, the tops are olive green, striped with creamy yellow, the undersides are purplish. Because of its dangling growth, Callisia is best displayed in a hanging basket or on a pedestal.
Callisia has succulent stems that support solid green or variegated, pointed oval leaves that are 1 to 8 inches long. The leaves grow erect, but droop as they mature.
Callisia resembles Tradescantia and Zebrina. Its stems stan erect when young, then start to droop as they reach their mature 2 to 3 feet (61-91cm) length.
Callisia is a genus of about 20 species native to forest margins in southeast United States, Mexico, and tropical North and South America.
