Cyclamen persicum · also called Florist's cyclamen, Persian cyclamen, Sowbread
⚠ Toxic to pets
Toxic to cats and/or dogs — keep out of reach.
A cool-season bloomer with swept-back, butterfly-like flowers above marbled heart-shaped leaves, cyclamen flowers through winter and then goes dormant. It is a tuberous plant with very particular temperature needs.

Toxic to pets
Light
Cyclamen want bright, indirect light during their winter growing-and-flowering season; an east window or bright cool room suits them. They do not want hot direct sun, which shortens bloom and pushes the plant toward dormancy too soon. Good light keeps the flower stems sturdy and the marbled foliage compact.
Water
Keep the soil consistently moist but never waterlogged while in active growth, and water from below or at the soil edge — water sitting in the crown over the tuber causes rot. Let the surface dry slightly between waterings. As the plant finishes flowering and leaves yellow in spring, taper off water to let it rest dormant through summer.
Soil & potting
Use a well-draining, organic-rich potting mix and a pot with drainage. When potting, leave the top of the tuber slightly exposed above the soil line rather than buried, which helps prevent crown rot. Many growers repot dormant tubers in late summer before the next season.
Environment — humidity, temperature, placement
Cyclamen are cool-season plants and the single biggest mistake is keeping them too warm: they thrive in cool rooms (think chilly windowsills and bright porches) and rapidly yellow, wilt, and go dormant in hot, dry, centrally heated air. Give them cool nights, bright light, and steady moisture. After flowering they naturally go dormant for the summer and can be rested dry and cool, then revived in autumn.
Propagation
Cyclamen are grown from seed rather than easy cuttings or division; the tuber does not divide cleanly like some bulbs and cut pieces tend to rot. Sown seed germinates slowly in cool, dark conditions and takes many months to a year-plus to reach flowering size. For most owners, the realistic goal is reblooming the same tuber year after year rather than propagating new plants.
Toxicity detail
Toxic to cats and dogs. The ASPCA lists Cyclamen as toxic due to saponins (notably terpenoid saponins), concentrated most heavily in the roots and tubers. Ingestion of foliage or flowers typically causes drooling, vomiting, and diarrhea; ingestion of large amounts of tuber can cause more serious effects including heart-rhythm abnormalities and seizures. Keep cyclamen, and especially the tuber, away from pets and seek veterinary care if eaten. Source: ASPCA Animal Poison Control toxic-plant database.
Origin & history
Cyclamen persicum hails from the eastern Mediterranean and was developed over the 19th and 20th centuries into the large-flowered 'florist's cyclamen' sold as a winter gift plant, in shades from white through pink to deep red. The old folk name 'sowbread' refers to wild pigs reportedly rooting up and eating the tubers. The plant has a long presence in Mediterranean gardens and herbal lore, where its toxicity was also recognized.
Growth stages
How this plant changes through its life — each stage often has its own care, diet and space needs.
Photo coming soon
Seed
Most plants begin as a seed (or spore in ferns) — a dormant package holding the embryo and a food reserve within a protective coat. Given moisture, warmth, and sometimes light, the seed breaks dormancy and germinates.
Photo coming soon
Seedling
The seedling emerges with a root and its first leaves (cotyledons), then true leaves. It is tender and shallow-rooted, dependent on steady moisture and light as it establishes the beginnings of stem and root systems.

Vegetative growth
In the vegetative phase the plant focuses on growing roots, stems, and foliage, building the size and structure it needs before flowering. This is the main period of leafing out and, for many houseplants, the stage at which they are grown and propagated.
Mature / Flowering
A mature plant reaches its full habit and, when conditions and age allow, flowers and sets seed (or, for foliage plants, simply attains its full adult size and form). This is the stage shown in most reference photos.
Problems & solutions
Each problem lists a proven fix (horticulture / extension-backed) and, where useful, an anecdotal remedy from the grower community — clearly labeled so you can judge for yourself.
Yellowing leaves and collapse in a warm room
moderate
Symptoms:Leaves rapidly turn yellow, flowers fade, and the plant wilts soon after coming indoors.
Likely cause:Excess heat. Cyclamen are cool-season plants; warm, dry, centrally heated air makes them think the season is over and pushes them toward premature dormancy.
✓ Proven fix
Move the plant to the coolest bright spot available — an unheated porch, a chilly windowsill, or a cool room — and keep it evenly moist. In cool conditions it will bloom for months. If it has already begun yellowing widely, let it ease into dormancy and revive it in autumn.
◇ Anecdotal remedy — grower lore, unverified
Growers commonly keep cyclamen in a bright, unheated entryway or stairwell, insisting the 'fridge-cold' draft is exactly what the plant wants.
Crown / tuber rot
severe
Symptoms:The center of the plant where the leaves emerge turns soft, brown, and mushy, often with a bad smell.
Likely cause:Water pooling in the crown over the top of the tuber, overwatering, or a tuber buried too deep. The crown rots easily when wet.
✓ Proven fix
Water from below or at the pot edge to keep the crown dry, let the surface dry slightly between waterings, and pot with the top of the tuber slightly above the soil. Once the crown has rotted the plant is usually lost, so prevention is key.
◇ Anecdotal remedy — grower lore, unverified
Some growers set the pot in a shallow tray for a timed soak, then remove it, reasoning that bottom-watering all but eliminates crown rot.
Fails to rebloom after dormancy
mild
Symptoms:The summer-dormant tuber stays bare or grows only a few weak leaves in autumn.
Likely cause:Insufficient rest, the tuber kept too warm or too wet during dormancy, or a lack of cool, bright conditions when growth should resume.
✓ Proven fix
Rest the tuber on the dry side in a cool, shaded place through summer, then in late summer/autumn refresh the potting mix, resume watering, and move it to a cool, bright spot to trigger new growth and buds.
◇ Anecdotal remedy — grower lore, unverified
Experienced growers often tip the dormant pot on its side outdoors in a shady corner all summer, then 'wake' it with a thorough watering when nights turn cool.
Anecdotes & grower lore
Community experience and cultural notes — not horticultural guarantees. Conditions vary by home; treat these as colour, not prescriptions.
Cyclamen owners trade the hard-won wisdom that these are 'cold-loving' plants — newcomers despair when a supermarket cyclamen collapses on a warm windowsill, while veterans keep theirs on an unheated porch and are rewarded with months of bloom. There is also a satisfying ritual around dormancy: the plant 'disappears' for the summer, and bringing a bare tuber back into growth each autumn feels, to many growers, like a small annual resurrection.
