Genus of 4 species of rhizomatous perennials from moist, tropical woodland and rocks in Mexico. In general, these plants are good and decorative subjects for the indoor light garden or the tropical greenhouse. Most are grown for their attractive flowers, although some species and hybrids of Smithiantha also produce very attractive hairy and plush foliage. Smithiantha is not an easy plant to grow in the average room - it needs the warm humid conditions. It is raised from rhizomes planted on their sides in potting compost in late winter - they should be 1/2 in. below the surface.
