Paradox Sundew care

Light

Paradox Sundew 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. Requires high light — at least 4–6 hours of direct or very bright indirect sun daily during the growing season. A south-facing windowsill in the UK, or a south/west-facing window in the US, is suitable; supplemental grow lighting for 14 hours is recommended in winter. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water paradox sundew wet tray (growing season); nearly dry (dry season / 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. During the wet growing season (spring to autumn), keep 2–3 cm of pure water in the tray. In the dry rest period reduce water significantly — keep the soil just barely moist to prevent complete desiccation; never waterlog in cool conditions.

Soil and pot

Paradox Sundew grows best in sandy carnivore mix — peat and coarse silica sand. Use a 1:1 or 2:1 blend of peat (or coir) and coarse, lime-free silica sand. Avoid perlite alone as it can retain too much moisture in the rest phase. The mix must be completely nutrient-free. 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

Paradox Sundew sits happiest at around 50–80% (growing season); 30–50% (rest season) humidity and 18–38 °C (growing season); 18–25 °C (rest) (64–100 °F (growing season); 64–77 °F (rest)). Moderate to high humidity during active growth; lower humidity during dormancy mimics the dry Australian winter. A drop in humidity combined with reduced watering triggers healthy dormancy. If you keep the room above 18–38 °C (growing season); 18–25 °C (rest) 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 paradox sundew sparingly. Feed 3–5 times during the growing season by placing a small insect on an active dewy leaf; never apply liquid or granular fertiliser to the soil. 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 paradox sundew in the Growli community. Each is annotated with the most common cause so you know where to start.

• Failure to re-sprout after dormancy — If kept too cold or too wet during dormancy the rhizome rots. Ensure temperatures stay above 18 °C and the soil is only barely moist — not waterlogged — through the rest period.
• Fungal crown rot — Stagnant water around the crown in cool conditions encourages Botrytis and Pythium. Improve air circulation, reduce tray water depth, and avoid overhead watering during cooler months.

Propagation

Division of the rhizome at the start of the growing season is the most reliable method. Leaf cuttings are less successful for petiolaris complex species than for other Drosera; seed germination requires very fresh seed and warm temperatures. 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

Paradox Sundew is pet-safe. Drosera paradoxa is not listed as toxic to cats or dogs by the ASPCA. No toxic principles are documented in Drosera; the sticky enzymes may cause transient mouth irritation but pose no systemic risk. 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.
