Care at a glance

Light

Flesh-pink Sinningia 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. Prefers bright, filtered light from an east- or north-facing window; avoid prolonged direct summer sun which scorches the soft, hairy leaves. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water flesh-pink sinningia every 7–10 days in growth; near-dry during dormancy. 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. Keep the compost evenly moist but never waterlogged during active growth; taper off watering as leaves yellow and die back to encourage dormancy.

Soil and pot

Flesh-pink Sinningia grows best in well-draining, humus-rich mix. A mix of peat-free multipurpose compost with perlite and leaf mould suits the species' preference for moisture-retentive but airy growing medium. 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

Flesh-pink Sinningia sits happiest at around 50–65% humidity and 16–26 °C in growth; 10–13 °C acceptable during dormancy (61–79 °F in growth; 50–55 °F during dormancy). Provide moderate ambient humidity; grouping plants together or using a pebble tray filled with water achieves the necessary level without wetting leaves. If you keep the room above 16–26 °C in growth; 10–13 °C acceptable during dormancy 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 flesh-pink sinningia sparingly. Feed every two weeks with a high-potassium liquid fertiliser during the flowering season; cease feeding once dormancy begins. 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 flesh-pink sinningia in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Botrytis (grey mould)Cool, humid, still conditions trigger grey mould on flowers and leaves; improve air circulation and remove affected parts promptly. Avoid wetting foliage when watering.
  • MealybugsWhite cottony masses appear at leaf axils and on the tuber surface; treat with a cotton swab dipped in isopropyl alcohol and follow up with neem oil spray.

Propagation

Stem tip cuttings root in moist perlite at 21–24 °C. Leaf-petiole cuttings can be used. Seeds sown on the surface of moist, fine gesneriad mix germinate in 2–4 weeks at 22 °C. 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

Flesh-pink Sinningia is mildly toxic to pets. The ASPCA lists Sinningia speciosa (Gloxinia) as non-toxic to cats, dogs, and horses, but S. incarnata is not individually listed in the ASPCA database. Classified as mildly toxic as a precaution; plant material may cause mild gastrointestinal upset if ingested. 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.

Flesh-pink Sinningia care — frequently asked questions

What is the common name for Sinningia incarnata?

Sinningia incarnata is most commonly called Flesh-pink Sinningia, but it is also known as Flesh-pink Sinningia, Pink Gloxinia. The names refer to the same species, so care instructions for Flesh-pink Sinningia apply identically to anything sold as Pink Gloxinia.

How much light does flesh-pink sinningia need?

Flesh-pink Sinningia grows best in bright indirect light (just back from a sunny window). Prefers bright, filtered light from an east- or north-facing window; avoid prolonged direct summer sun which scorches the soft, hairy leaves.

How often should I water flesh-pink sinningia?

Water flesh-pink sinningia every 7–10 days in growth; near-dry during dormancy. Keep the compost evenly moist but never waterlogged during active growth; taper off watering as leaves yellow and die back to encourage dormancy. 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 flesh-pink sinningia toxic to cats and dogs?

Flesh-pink Sinningia is mildly toxic to pets. The ASPCA lists Sinningia speciosa (Gloxinia) as non-toxic to cats, dogs, and horses, but S. incarnata is not individually listed in the ASPCA database. Classified as mildly toxic as a precaution; plant material may cause mild gastrointestinal upset if ingested.

What USDA hardiness zone does flesh-pink sinningia grow in?

Flesh-pink Sinningia is rated for USDA zone 10–12 (indoor in most climates) and RHS hardiness H1b. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
