African violets are native to high elevations in tropical eastern Africa. They are small, hairy, usually stemless herbaceous plants with crowded, long-stalked leaves. The violet, white, or pink flowers bloom most of the year. They are popular houseplants, and hundreds of varieties have been developed, including half-sized miniatures.
