About Black Gold clog plant

Nematanthus 'Black Gold' · also called Black Gold clog plant, Black Gold goldfish plant · houseplant

A dramatic Nematanthus hybrid cultivar distinguished by its very dark, near-black glossy foliage and brilliant gold-orange pouched flowers that provide striking contrast. An excellent hanging-basket plant that blooms prolifically in good indirect light. Like other clog plants, it needs warm, humid indoor conditions and consistent but not excessive moisture to perform at its best.

Preferred mix: Light, free-draining gesneriad or epiphytic mix

Watch for — Root rot: Overwatering in a heavy compost causes root rot quickly. Use a fast-draining mix and a pot with drainage holes; let the top layer of soil dry between waterings.
