About Aeschynanthus tricolor

Aeschynanthus tricolor · also called tricolor lipstick plant, three-colour aeschynanthus · flowering

Aeschynanthus tricolor is a trailing Bornean lipstick plant in the gesneriad family, grown for striking tubular red flowers marked with yellow and dark maroon-black stripes. A warm-growing epiphyte, it thrives in bright indirect light, high humidity, and a fast-draining mix, cascading beautifully from a hanging basket. Crucially, the whole Aeschynanthus genus is ASPCA non-toxic to cats and dogs.

Mature size: Stems trail to 45-60 cm or more, spreading to around 30-45 cm.

Indoor size vs how big it gets in the wild

Aeschynanthus tricolor does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims. Indoors and in a pot, expect stems trail to 45-60 cm or more, spreading to around 30-45 cm.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Growth rate and years to mature

Aeschynanthus tricolor is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: feed every one to two weeks through spring and summer with a balanced or bloom-boosting liquid fertiliser at half strength; this fuels its prolific flowering. cut back to monthly or none in autumn and winter while growth slows.

How to keep aeschynanthus tricolor smaller

You are not stuck with the maximum size. For aeschynanthus tricolor specifically, these are the levers, in order of impact:

Trim the longest vines back to the length you want — aeschynanthus tricolor takes hard cutting well and bushes out from the cut.
Cut just above a leaf node; each trimmed stem usually branches into two, so pruning makes it fuller, not sparser.
The cuttings root easily in water or mix, so "keeping it smaller" doubles as free new plants.
A trim once or twice a season is usually enough to hold its length.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of aeschynanthus tricolor should stop — you can be aggressive; it regrows readily.
Cut just above a node. Snip about 0.5 cm above a leaf node so the stem branches there instead of dying back.
Root the cuttings. Drop the trimmed pieces in water or mix — they root in 2-4 weeks and can fill the same pot for a bushier look.
Repeat as it runs. Re-trim whenever it overshoots; regular light pruning keeps it both smaller and fuller.

How to grow aeschynanthus tricolor bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for aeschynanthus tricolor the accelerators are:

Good light plus a moss pole or trellis triggers the longest, fastest, largest-leaved growth.
Give it something to climb — many vines grow far faster and bigger up a support than trailing.
Feed through spring and summer and keep it consistently watered while it is actively running.

Light is almost always the ceiling. The aeschynanthus tricolor light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When aeschynanthus tricolor outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for aeschynanthus tricolor:

Vines pooling on the floor or wrapping past where you want them — purely a trimming cue, not a repot one.
Bare, leggy stems with leaves only at the tips (usually a light problem, not a size one).
A tangled mass that has outrun its support and needs cutting back and re-training.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the aeschynanthus tricolor repotting guide. If you want more of this plant instead of a bigger one, the aeschynanthus tricolor propagation guide turns prunings into new plants.
