Aeschynanthus radicans, the Lipstick Plant, is a trailing epiphyte from the rainforests of Southeast Asia, named for the scarlet tubular flowers that slide out of dark maroon buds like lipstick from a case. It wants bright indirect light, warmth, and a little root snugness to bloom well, and its waxy leaves forgive the occasional missed watering. This handbook covers Aeschynanthus radicans, its light and watering rhythm, and how to coax those signature red blooms.

Lipstick Plant — Aeschynanthus radicans

Aeschynanthus radicans, the lipstick plant, is a trailing epiphyte from Southeast Asia with glossy, slightly waxy leaves and bright red tubular flowers that slide out of dark maroon buds.

Quick facts

• Light: lots of bright light and some direct sun for the best colour.
• Water: deeply every ~9 days, far less in winter.
• Temperature: 60-85F (16-29C).
• Humidity: it likes a humid spot or a pebble tray.
• Soil: a moisture-retentive but well-aerated mix.
• Propagate: a stem cutting.
• Pet: generally safe around pets.

The flowers earn the plant its name: each scarlet bloom emerges from a deep-purple tubular calyx exactly like lipstick twisting up out of its case.

General Care Principles

No matter the species in this handbook, a handful of principles carry most of the weight. Get these right and the individual notes above become fine-tuning.

Water on the plant's schedule, not the calendar. Soak thoroughly, then let the soil dry before the next drink. In winter, ease right off — most of these plants want a cool, dry rest.

Use the right soil and a draining pot. Free-draining for succulents, moisture-retentive but aerated for ferns and foliage. A drainage hole is non-negotiable.

Propagate to multiply. Almost every plant here can be cloned from a leaf, offset, division, or cutting — see each species for its best method.

Frequently Asked Questions

How often should I really water?

Forget frequent sips. Soak the soil completely, then let it dry out fully before the next drink. In winter most of these plants want a long, dry rest. The lift test (light pot = dry) beats any calendar.

My plant is stretching and pale — what does that mean?

It wants more light. Move it to a brighter window or add a full-spectrum LED grow light. New growth will be compact and colourful; the stretched part will not undo itself, so behead and re-root the top if you like.

What soil should I use?

A free-draining mix is non-negotiable. For succulents that means gritty, sandy soil in a pot with a real drainage hole. For leafy types a peat-free houseplant mix is fine. Sitting in wet soil is the fastest route to rot.

Is this plant safe around my pets?

We note pet safety per species in this guide. 'Pet-safe' means it is not on the usual toxic lists, but no plant is food — keep curious cats and dogs from chewing leaves, and call a vet if you are worried.
