About Aeschynanthus radicans 'Curly Q'
Aeschynanthus radicans 'Curly Q' · also called Twisted lipstick plant · flowering
Aeschynanthus 'Curly Q' is a lipstick plant whose waxy dark leaves twist and curl along trailing stems, ending in tubular red flowers that emerge from dark calyx 'tubes'. An epiphytic tropical, it likes bright indirect light, a chunky airy mix and a slight dry-down between waterings. Ideal in hanging baskets, and ASPCA pet-safe.
Preferred mix: Light, airy, free-draining epiphytic mix
Watch for — Leaf drop: Often a response to cold draughts, sudden temperature swings or letting the mix dry out fully; keep it warm, draught-free and evenly cared for.
Why aeschynanthus radicans 'curly q' needs this mix
Aeschynanthus radicans 'Curly Q' 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 radicans 'Curly Q' 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 radicans 'curly q' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Dense, water-holding compost rots aeschynanthus radicans 'curly q' 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 radicans 'curly q' 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 radicans 'curly q'?
Aeschynanthus radicans 'Curly Q' 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

Drainage and the pot
