Care at a glance

Light

Single-flower Lipstick Plant is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Needs bright, indirect light to bloom; position close to an east-facing window or use sheer curtains on a south-facing window — insufficient light is the most common reason this species fails to flower indoors. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water single-flower lipstick plant when top 2 cm of compost dry out. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Water with room-temperature soft water or rainwater; allow the compost to partially dry between waterings and reduce frequency in winter, ensuring the pot drains freely after each watering.

Soil and pot

Single-flower Lipstick Plant grows best in light, airy epiphytic mix. A mix of fine bark chips, perlite, and peat-free compost provides the fast drainage and air-filled porosity that epiphytic roots require; repot only when roots fill the container. 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

Single-flower Lipstick Plant sits happiest at around 60–80% humidity and 16–27°C (61–80°F). Requires high humidity to thrive; use a humidity tray or group with other tropical houseplants, and avoid placing near radiators or air-conditioning vents that cause rapid moisture loss. If you keep the room above 16–27°C 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 single-flower lipstick plant sparingly. Feed fortnightly with a dilute, balanced liquid fertiliser during the growing season (spring to early autumn); avoid high-nitrogen feeds which promote foliage at the expense of flowers. 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 single-flower lipstick plant in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Failure to flower indoorsThe most common complaint; caused by insufficient light or overly warm, stable conditions year-round — provide a brief, cooler resting period (15–18°C) in late autumn to stimulate bud initiation.
  • Root rot from waterlogged compostAs an epiphyte, Aeschynanthus uniflorus is highly sensitive to root suffocation; ensure the potting mix and container drain rapidly, and never allow roots to sit in collected water.

Propagation

Stem-tip cuttings of 8–10 cm taken in spring, rooted in a moist, free-draining propagating mix at 22–25°C under a humidity tent or propagator lid. 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

Single-flower Lipstick Plant is pet-safe. Aeschynanthus (lipstick plant) is listed by the ASPCA as non-toxic to dogs, cats, and horses; ingestion may cause mild, transient gastrointestinal 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.
