About

Nematanthus gregarius, also called the clog plant or goldfish plant, is a species of flowering plant from Brazil in the gesneriad family, Gesneriaceae, making it a relative of such genera as Streptocarpus (African violets) and Aeschynanthus (lipstick plants).

How to grow it

As it does not tolerate temperatures below 10 °C (50 °F), in temperate zones, this plant requires the protection of glass, greenhouses, or must be kept as a houseplant during the colder months, preferably near a bright southern window, but not placed directly in full sunlight for extended periods as the foliage may burn. It is often kept permanently as a houseplant, in hanging baskets which highlight its trailing habit. In appropriate environments, such as Florida, Hawaii, or Southern California, N. gregarius may be seen in outdoor gardening and landscaping projects. This plant is readily propagated and reproduced commercially via vegetative reproduction.

Nematanthus gregarius has received the Royal Horticultural Society's Award of Garden Merit.
