Ctenanthe (pronounced te-NANTH-ee) plants are famous for their striking variegated foliage, and the cultivar Ctenanthe setosa 'Grey Star' is no exception. It is a clump-forming plant with long oblong leaves, grey with darker green veins. Although it can produce white blooms when grown indoors, 'Grey Star' rarely flowers—this plant is all about the dramatic foliage. This evergreen, clump-forming, herbaceous perennial has large, thick leaves that feature dark green and silvery-gray stripes on the top. The undersides are also beautiful with their distinctive purple or maroon shades. Although it can be grown as a garden plant in zones 10 to 11, in most regions Ctananthe plants are usually grown as houseplants. 'Grey Star' is a slow-growing plant that is usually planted in late spring or early summer when used as a garden plant.
