Nematanthus gregarius

Goldfish plant

A Brazilian epiphytic gesneriad with small, glossy, fleshy leaves and pouched orange flowers shaped like a goldfish or clog. It is one of the commonest goldfish plants in cultivation. It is easy in bright indirect light, a slightly root-bound pot and moderate humidity, and it flowers best after a cooler spell.

Where it grows wild

An epiphytic subshrub that grows on trees, and in the genus less often in humus-filled pockets on rocks. Hummingbirds visit the flowers. In the wild it reaches about 0.5 m tall and 1 m across.

The sources give no elevation for this species. Its tolerance of cool spells suggests it is not confined to the warm lowlands.
