Care at a glance
Light
Bright but filtered. Hairy Sinningia burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Prefers bright, indirect light; a position within 1–1.5 m of a south- or east-facing window is ideal, but screen from harsh midday sun to prevent leaf scorch. 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 hairy sinningia: weekly during growth; withheld during dormancy. 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 when the top 2–3 cm of compost are dry; avoid wetting the hairy foliage as moisture trapped in the pubescence encourages fungal rot.
Soil and pot
Hairy Sinningia grows best in free-draining organic mix. Use a blend of peat-free multipurpose compost with added perlite (roughly 2:1) to ensure good drainage and aeration around the tuber. 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
Hairy Sinningia sits happiest at around 50–65% humidity and 12–26°C (54–79°F). Appreciates moderate to moderately high humidity; do not mist the hairy leaves directly — use a pebble tray or room humidifier instead. If you keep the room above 12–26°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 hairy sinningia sparingly. Apply a high-potassium liquid feed every two weeks from spring until flowering ends; withhold completely during winter dormancy. 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 hairy sinningia in the Growli community. Each is annotated with the most common cause so you know where to start.
- Crown rot from wet leaves — Water sitting in the hairy crown or rosette rapidly leads to fungal crown rot; always water at the base and avoid overhead irrigation.
- Failure to re-sprout after dormancy — Tubers stored too cold (below 10°C) or kept in wet compost over winter often fail to break dormancy; store dry at 12–15°C in barely moist sand or dry compost.
Propagation
Divide tubers carefully in early spring, ensuring each section has at least one growth point; leaf-petiole cuttings can also be rooted in a warm, humid propagator in summer. 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
Hairy Sinningia is pet-safe. Sinningia (Gloxinia group) is listed by the ASPCA as non-toxic to cats and dogs; ingestion of plant material may cause mild gastrointestinal upset in sensitive animals. 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.
Hairy Sinningia care — frequently asked questions
What is the common name for Sinningia villosa?
Sinningia villosa is most commonly called Hairy Sinningia, but it is also known as Hairy Sinningia, Hairy Gloxinia. The names refer to the same species, so care instructions for Hairy Sinningia apply identically to anything sold as Hairy Gloxinia.
How much light does hairy sinningia need?
Hairy Sinningia grows best in bright indirect light (just back from a sunny window). Prefers bright, indirect light; a position within 1–1.5 m of a south- or east-facing window is ideal, but screen from harsh midday sun to prevent leaf scorch.
How often should I water hairy sinningia?
Water hairy sinningia weekly during growth; withheld during dormancy. Water thoroughly when the top 2–3 cm of compost are dry; avoid wetting the hairy foliage as moisture trapped in the pubescence encourages fungal rot. 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 hairy sinningia toxic to cats and dogs?
Hairy Sinningia is pet-safe. Sinningia (Gloxinia group) is listed by the ASPCA as non-toxic to cats and dogs; ingestion of plant material may cause mild gastrointestinal upset in sensitive animals.
What USDA hardiness zone does hairy sinningia grow in?
Hairy Sinningia is rated for USDA zone 9-11 and RHS hardiness H2. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
