Sinningia

 

a genus of perennial herbs or subshrubs of the family Gesneriaceae. The plants have well-developed tubers and downy leaves. The flowers are usually large and pentamer-ous, and they have a bright bell-shaped corolla. There are approximately 15 species, distributed in South America. The gloxinia (Sinningia speciosa) and several other species have been used to create many varieties with a multicolored double corolla. Hybrids are raised in greenhouses and as houseplants; they flower in April and May and are easily propagated by seeds, tubers, or leaf cuttings.
