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
Why anoectochilus roxburghii needs this mix
Anoectochilus roxburghii is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Anoectochilus roxburghii is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons anoectochilus roxburghii struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates anoectochilus roxburghii's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for anoectochilus roxburghii.
pH — does it matter for anoectochilus roxburghii?
Anoectochilus roxburghii is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
