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.
Why black gold clog plant needs this mix
Black Gold clog plant drinks mostly through its central cup, not its roots — so it wants a light, open, fast-draining bark mix and only a shallow pot.
- Black Gold clog plant is an epiphyte: its small root system mainly clings on, while the rosette "tank" does the drinking — so the mix only needs to anchor it and breathe.
- An open bark mix lets the few roots get air and dries fast, mimicking the tree-fork or rock crevice it grows in naturally.
- Because the cup feeds it, a soggy root zone gives no benefit and only invites base rot.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons black gold clog plant struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Dense, water-holding compost rots black gold clog plant at the base where the leaves meet the soil — the rosette can look fine while the crown is already failing.
- A deep pot full of mix stays wet in the middle long after the surface dries; bromeliad roots are too shallow to ever use it.
- Garden topsoil compacts and starves the few roots of air.
Potting black gold clog plant deep in ordinary compost as if the roots do the feeding. Use a shallow pot of open bark mix and keep the soil only barely moist.
pH — does it matter for black gold clog plant?
Black Gold clog plant likes a slightly acidic mix (around pH 5.0-6.0), which a bark-based blend gives naturally. Cup-water quality matters more than soil pH — use rain or filtered water.
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.
DIY mix vs a bagged one
A bagged epiphytic or orchid mix works well for black gold clog plant with a little extra perlite. The DIY ratio above is easy and cheap if you already keep orchids.
Drainage and the pot
A shallow, well-drained pot is ideal — the rootball should never sit in water. Keep the central cup topped up instead; that is how the plant actually drinks.
Black Gold clog plant rarely needs repotting — it flowers once then produces pups. Move pups to fresh bark mix; bark breakdown is slow enough that the parent rarely needs it. When the time comes, our repotting guide for black gold clog plant covers the timing and technique step by step.
