About Aeschynanthus lobbianus

Aeschynanthus lobbianus · also called lipstick plant, Lobb's lipstick vine · flowering

Aeschynanthus lobbianus, a lipstick plant, is a trailing epiphytic gesneriad from Southeast Asia, named for bright red tubular flowers that emerge from dark, lipstick-like calyces along cascading stems of thick, waxy leaves. It is superb in hanging baskets, flowering best with bright indirect light, warmth, moderate-to-high humidity and a slightly snug pot.

Preferred mix: Light, airy, free-draining epiphytic mix

Watch for — No flowers: Too little light is the most common cause, along with a too-large pot. Provide bright indirect light, keep the plant slightly pot-bound, and feed with a high-potash liquid in summer.

Why aeschynanthus lobbianus needs this mix

Aeschynanthus lobbianus drinks mostly through its central cup, not its roots — so it wants a light, open, fast-draining bark mix and only a shallow pot.

What goes wrong with the wrong mix

The wrong soil is one of the most common reasons aeschynanthus lobbianus struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:

Potting aeschynanthus lobbianus 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 lobbianus?

Aeschynanthus lobbianus 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 lobbianus 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 lobbianus 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 lobbianus covers the timing and technique step by step.

2 parts orchid bark or coarse epiphytic mix : 1 part perlite : 1 part peat-free compost. Aeschynanthus lobbianus 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.

Can I use normal potting soil for aeschynanthus lobbianus?
