Deep green leaves mottled with silver-white push up through cold soil, then small pink flowers open in pillows beneath bare trees: the Cos Island cyclamen (Cyclamen coum) is one of the rare plants that flower in the depths of winter. Give it shade and light, well-drained soil, for it fears standing water far more than frost.

Set bulbs 8 to 10 inches apart; they spread alone

It is recommended to plant the cyclamen bulbs in spring, at the end of summer or at the beginning of fall.

  • Cyclamen likes light and well drained soil.
  • This particular cyclamen species is more vulnerable to excess water than it is to freezing.
  • Space bulbs more or less 8 to 10 inches (10-15 cm) apart, and nature will do its part in multiplying the plant on its own.

Cyclamen coum in pots:

Cyclamen coum is suited for planting both in a pot and a garden box.

  • For planting this coum cyclamen in pots, garden boxes or containers, use a special bulb plant soil mix, and make doubly sure that the container has a hole at the bottom.

You can also pair cyclamen with other early Spring bulbs such as snowdrop. If you’d rather have a cyclamen that blooms in Autumn, choose the ivy-leaved Cyclamen instead.

Cyclamen coum, ivy-leaved cyclamen or snowdrop?

All three are small bulbs for the same cool, shaded corners, but they take their turn at different moments of the year. Choose according to the season you want to fill.

Cyclamen coum, ivy-leaved cyclamen or snowdrop?
Plant Flowering season Where to plant Why choose it
Cyclamen coum Midwinter Shade and part shade, cool soil One of the rare plants that flower in winter, in any climate or region
Ivy-leaved cyclamen Mid-autumn Same shaded spots as Cyclamen coum The cyclamen to pick if you would rather have autumn colour
Snowdrop Early spring Alongside the cyclamen, in the same bed A companion bulb that carries the display on into spring

Plant two or three of them together and the same shaded patch stays in flower from autumn through to spring.

Cyclamen coum care

No care is needed apart from planting, since the cyclamen coum can take care of itself.

  • Never remove any leafage before it has completely wilted away, or you might not have any flowers on your cyclamen coum anymore.
  • Avoid mowing over it if leaves are still present.
  • In pots, you can feed it with bulb flower fertilizer. Do this once a year in Fall.

Watering Cyclamen coum:

Rainfall is usually perfectly enough: cyclamen coum is dormant during Summer droughts, which it can resist very well. If, however, the summer was quite dry and you feel that your cyclamen are having trouble sprouting, simply help them along by watering a bit.
