About Tweedie's Lipstick Plant
Aeschynanthus tweediei · also called Tweedie's Lipstick Plant, Tweedie's Basket Vine · tropical
Aeschynanthus tweediei is an epiphytic gesneriaceae species from the tropical rainforests of Southeast Asia, closely related to the common lipstick vine and sharing its characteristic tubular flowers and trailing growth habit. It is a specialist collector's species seldom seen outside botanical gardens and specialist nurseries, prized for its compact, neat trailing stems and vibrant blooms. Like all Aeschynanthus, it requires consistently warm temperatures and should never be exposed to temperatures below 15°C. The ASPCA lists Aeschynanthus (lipstick plant) as non-toxic to cats and dogs.
Preferred mix: Coarse epiphytic mix with excellent drainage
Why tweedie's lipstick plant needs this mix
Tweedie's Lipstick 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.
- Tweedie's Lipstick 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 tweedie's lipstick plant struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Dense, water-holding compost rots tweedie's lipstick 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 tweedie's lipstick 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 tweedie's lipstick plant?
Tweedie's Lipstick 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 tweedie's lipstick 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.
Tweedie's Lipstick 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 tweedie's lipstick plant covers the timing and technique step by step.
