Petrocosmea Overview

Petrocosmea is a genus containing around 44 evergreen perennials in the African violet family, Gesneriaceae. Most species are endemic to western China, where they are found naturally in high-altitude locations. These plants are adapted to moist, forest environments where they are typically found growing on mossy rocks. These low-growing, tender plants produce fleshy foliage arranged in rosettes, the lance-shaped to rounded leaves are often covered in fine hairs, creating a felted texture. Flowers are attractive and showy, borne in small clusters on upright stems above the foliage, they are tubular to bell-shaped and 5 lobed. They appear from spring-summer and may be pink, purple or white.
