Care at a glance

Light

Bright but filtered. Aeschynanthus lobbianus burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Bright indirect light is essential for flowering; an east or filtered south window works well, and a couple of hours of soft morning sun is tolerated. Insufficient light leads to leggy, flowerless growth; harsh direct sun scorches the waxy leaves. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering aeschynanthus lobbianus: when the top 2-3 cm of soil is dry, roughly every 7-10 days. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Water thoroughly, then let the top of the mix dry before watering again; the fleshy leaves store moisture and the plant resents constant wetness. Reduce watering slightly in winter, but never let the rootball dry out completely.

Soil and pot

Aeschynanthus lobbianus grows best in light, airy, free-draining epiphytic mix. Use an open, well-aerated blend such as peat-free potting mix with plenty of perlite, orchid bark and a little coir, reflecting its epiphytic roots. Sharp drainage is key to preventing root rot. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Aeschynanthus lobbianus sits happiest at around 50-70% humidity and 18-27°C (65-80°F). Prefers moderate to high humidity for the most flowers and lush foliage, though the waxy leaves help it cope with average room air. A pebble tray or grouping raises humidity; avoid waterlogged conditions that cause leaf drop. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed aeschynanthus lobbianus sparingly. Feed every 2-4 weeks in spring and summer with a balanced or high-potash liquid fertiliser at half strength to promote flowering. Reduce to occasional feeding in autumn and winter when growth slows. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on aeschynanthus lobbianus in the Growli community. Each is annotated with the most common cause so you know where to start.

  • No flowersToo 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.
  • Leaf dropCold draughts, sudden temperature drops or overwatering trigger sudden leaf shedding. Keep above 15°C, away from draughts, and let the soil surface dry between waterings.
  • Root rotA heavy, water-retentive mix or constant sogginess rots the roots. Use an airy, free-draining epiphytic mix and empty any saucer of standing water.
  • Sticky leaves and pestsAphids and mealybugs target soft new growth and flower buds. Inspect leaf axils regularly and treat early with insecticidal soap or by wiping the stems.

Propagation

Easy from stem-tip cuttings about 8-10 cm long taken in spring or summer; remove the lower leaves and root in a light, moist mix or water under warmth and humidity. Several cuttings per pot give a fuller, faster-trailing plant. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Aeschynanthus lobbianus is pet-safe. ASPCA-listed as non-toxic to cats and dogs. The lipstick plant (Aeschynanthus, family Gesneriaceae) is on the ASPCA non-toxic list, classified non-toxic to cats, dogs and horses with no toxic principles. Safe around pets, though chewing the foliage may cause mild, transient stomach upset. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Aeschynanthus lobbianus care — frequently asked questions

What is the common name for Aeschynanthus lobbianus?

Aeschynanthus lobbianus is most commonly called Aeschynanthus lobbianus, but it is also known as lipstick plant, Lobb's lipstick vine. The names refer to the same species, so care instructions for Aeschynanthus lobbianus apply identically to anything sold as lipstick plant.

How much light does aeschynanthus lobbianus need?

Aeschynanthus lobbianus grows best in bright indirect light (just back from a sunny window). Bright indirect light is essential for flowering; an east or filtered south window works well, and a couple of hours of soft morning sun is tolerated. Insufficient light leads to leggy, flowerless growth; harsh direct sun scorches the waxy leaves.

How often should I water aeschynanthus lobbianus?

Water aeschynanthus lobbianus when the top 2-3 cm of soil is dry, roughly every 7-10 days. Water thoroughly, then let the top of the mix dry before watering again; the fleshy leaves store moisture and the plant resents constant wetness. Reduce watering slightly in winter, but never let the rootball dry out completely. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is aeschynanthus lobbianus toxic to cats and dogs?

Aeschynanthus lobbianus is pet-safe. ASPCA-listed as non-toxic to cats and dogs. The lipstick plant (Aeschynanthus, family Gesneriaceae) is on the ASPCA non-toxic list, classified non-toxic to cats, dogs and horses with no toxic principles. Safe around pets, though chewing the foliage may cause mild, transient stomach upset.

What USDA hardiness zone does aeschynanthus lobbianus grow in?

Aeschynanthus lobbianus is rated for USDA zone 10-11 (frost-tender; grown as a houseplant in most climates) and RHS hardiness H1b. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
