Aeschynanthus radicans

Lipstick plant

A trailing epiphytic gesneriad from the lowland and hill dipterocarp forests of southern Thailand, Peninsular Malaysia, Sumatra and Borneo. It hangs from trees or clambers over rocks, often beside streams. It lives in a warm, humid, non-seasonal climate with filtered light. It does best with steady warmth, bright indirect light, high humidity and an airy mix that stays lightly moist but never soggy.

Where it grows wild

An epiphyte on trunks and branches, or clambering over rocks, in lowland and hill dipterocarp forest. It is often found by streams and occasionally in swamp forest. The stems trail or hang, rooting along their length, in the humid lower-to-middle forest layers where light is broken and dappled.

The Malaysian revision gives 0–1000 m. The measured wild records span 10–1963 m with a median of 130 m, so it is essentially a lowland plant. The few records near 2000 m are above the published range and may be misidentified.
