Florist's Cyclamen (Persian Cyclamen) care

Light

In the wild florist's cyclamen grows on the bright edge of a forest canopy, not in the canopy and not in the open. Indoors, that translates to within a metre of an unobstructed window, sheer curtain optional. Prefers bright, indirect light away from direct sun, which scorches leaves. A north- or east-facing windowsill indoors suits it well during its winter blooming season. The fastest test: a hand held at the leaf casts a soft-edged shadow at noon — sharp shadow means too much sun, no shadow means too little light.

Watering

Aim for when the top 1-2 cm of soil feels dry, roughly every 5-7 days for florist's cyclamen, but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Water from the base by setting the pot in a tray of water for 20-30 minutes, then discard excess. Avoid wetting the corm or crown, which rots easily. Reduce watering when the plant enters summer dormancy and leaves yellow.

Soil and pot

Florist's Cyclamen grows best in well-draining peat-free compost with added perlite. A light, loamy mix with 20-30% perlite ensures good drainage. Slightly acidic pH of 5.5-6.5 suits growth. Good drainage prevents the corm from sitting in wet conditions. 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

Florist's Cyclamen sits happiest at around 40-60% humidity and 10-18°C (50-65°F). Average household humidity is acceptable. Mist around (not on) the plant or use a pebble tray to raise local humidity. Avoid direct heat sources that cause dry air. If you keep the room above 10 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 florist's cyclamen sparingly. Feed every 2-4 weeks during active growth (autumn through spring) with a low-nitrogen, high-potassium liquid fertiliser diluted to half strength. Do not feed during summer 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 florist's cyclamen in the Growli community. Each is annotated with the most common cause so you know where to start.

• Crown rot — Caused by overwatering or water pooling on the corm. Water from below and ensure excellent drainage.
• Yellow leaves — Often natural dormancy onset in late spring; can also signal overwatering, too much heat, or root-bound conditions.
• Failure to rebloom — The plant needs a cool dry rest period (summer dormancy) and a gradual temperature drop in autumn to trigger reflowering.
• Botrytis grey mould — Poor air circulation in damp conditions encourages fungal growth. Remove dead flowers promptly and improve ventilation.
• Vine weevil — Larvae feed on the corm. Check roots at repotting; treat with biological nematodes (Steinernema kraussei) in autumn.

Companion plants

Florist's Cyclamen pairs well with Primula vulgaris, Viola odorata, Helleborus niger, and Muscari armeniacum. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.

Propagation

Cyclamen persicum is most reliably propagated from fresh seed sown in late summer at 18°C in the dark; germination takes 4-6 weeks. Division of the corm is not generally recommended as the corm does not divide cleanly. 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

Florist's Cyclamen is toxic to pets. The ASPCA lists Cyclamen persicum as toxic to dogs, cats, and horses. All parts contain triterpenoid saponins, with the highest concentration in the corm/tubers; ingestion can cause vomiting, diarrhoea, and in large quantities cardiac abnormalities. Contact a vet promptly if a pet has chewed the plant. 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.
