About Anoectochilus roxburghii

Anoectochilus roxburghii · also called Roxburgh's Jewel Orchid, King of Jewel Orchids · houseplant

Anoectochilus roxburghii is a prized terrestrial jewel orchid grown for its dark velvety leaves laced with an intricate gold or coppery vein network. Native to Asian forest floors, it is more demanding than Ludisia, needing constant warmth, high humidity and an airy, moisture-retentive medium. Small white-and-yellow flowers appear on short spikes, but the foliage is the main draw.

Preferred mix: Live or fine sphagnum moss, or a humus-rich terrestrial orchid mix
