Streptocarpus (sect Saintpaulia)

The species and subspecies of plants collectively known as African violets belong to one of the smaller groups in the Old World Gesneriaceae. Wild populations are found chiefly in the area known as the Eastern Arc Mountains of Tanzania and Kenya. The plants grow on moss-covered boulders, on cliffs or on rock outcrops shaded by large trees. Because most African violets thrive in the same temperature and lighting conditions found in homes, they are one of the most important houseplants in the horticultural industry.
