Family: Gesneriaceae

Native to Mexico, this genus consists of four species of summer-flowering, tender perennials grown for their attractive, velvety foliage and terminal clusters of nodding tubular flowers.

Species

S. cinnabarina grows to 60 cm (24 in) high, producing red flowers, spotted yellow or white in the throat. The heart-shaped, deep green leaves have purple-streaked veins.

S. multiflora, to 75 cm (30 in), has velvety, dark green leaves and white or cream flowers, with yellow throats.

S. zebrina grows to 75 cm (30 in) high and has velvety, dark green leaves, with veins marked purple or brown. The scarlet and yellow flowers have spotted markings in the throat. Many fine hybrids of various species have been bred, including 'Orange King', with brilliant orange-red flowers through summer, and handsome deep green leaves, heavily marked in burgundy.

Cultivation

Outside the subtropics or tropics, grow as pot plants in an intermediate to warm greenhouse or conservatory. They also make good house plants. Pot or repot the rhizomes in spring, using shallow pots of soilless potting compost. Plants need good light (but shade from direct sun), and a very humid atmosphere. Do not overeater them. Gradually dry off plants in autumn and keep the rhizomes completely dry during the winter. Store them in a cooler place Smithianthas can be propagated from seed sown in spring and germinated at 18°C (64°F).

Climate

Warmest parts of zone 10 or tropical.
