Cyclamen is a winter-flowering plant with swept-back petals above patterned heart-shaped leaves. It is genuinely toxic to cats and dogs — especially the tuber — so keep it well out of reach of pets.

About Cyclamen

Cyclamen (Cyclamen persicum) is a winter-flowering plant from the eastern Mediterranean, with swept-back petals held above patterned, heart-shaped leaves. It grows from a tuber, stays compact at 15 to 25 cm, and lives in a small pot, so it brings flowers to a cool windowsill without taking much room. It blooms when most plants are resting, which is part of its appeal in a small flat.

Watering technique matters: water from below or at the soil edge, because water sitting in the crown rots the tuber. Keep it cool and bright, since it sulks and goes dormant in warm rooms. Expect it to die back and rest after flowering, which is normal. One firm warning: cyclamen is toxic to cats and dogs, especially the tuber, so keep it well out of their reach.

What it’s like to grow

Cyclamen is moderately fussy and very particular about water and warmth. Crown and tuber rot, from water sitting in the centre, is the usual cause of a sudden loss, so always water from below. Rapid yellowing and collapse mean the room is too warm; it wants cool and bright. The die-back after flowering is rest, not failure. If you have a cool spot and can water carefully, it's a fine choice. It is toxic to cats and dogs, the tuber especially, so it's not a safe choice in a pet household.

What to expect

It asks for a little consistency, but nothing fancy. No sunny window? It also does fine under a clip-on grow light.
