About Aeschynanthus speciosus
Aeschynanthus speciosus · also called orange lipstick plant, showy lipstick vine · flowering
Aeschynanthus speciosus is one of the showiest lipstick plants, producing dense terminal clusters of large orange-and-yellow tubular flowers above trailing stems of glossy green leaves. This epiphytic gesneriad blooms generously in summer given bright indirect light, warmth and humidity. Grow it in an airy mix in a hanging basket, keeping roots evenly moist but never waterlogged.
Preferred mix: Light, fast-draining epiphytic mix
Watch for — Yellowing lower leaves: Usually overwatering or poor drainage suffocating the roots. Let the surface dry between waterings and confirm the mix is airy and free-draining.
Why aeschynanthus speciosus needs this mix
Aeschynanthus speciosus drinks mostly through its central cup, not its roots — so it wants a light, open, fast-draining bark mix and only a shallow pot.
- Aeschynanthus speciosus 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 aeschynanthus speciosus struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Dense, water-holding compost rots aeschynanthus speciosus 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 aeschynanthus speciosus 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 aeschynanthus speciosus?
Aeschynanthus speciosus 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 aeschynanthus speciosus 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.
Aeschynanthus speciosus 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 aeschynanthus speciosus covers the timing and technique step by step.
