The winter flowering Cyclamen coum

It is said that you can have a cyclamen in flower every month of the year and January belongs to the diminutive Cyclamen coum.

The main flowering seasons for cyclamen are autumn and spring. The summer gap is filled with Cyclamen purpurascens and the rare C. colchicum and the winter is mainly left to Cyclamen coum.  Some spring cyclamens can flower very early, including the closely related C. alpinum and a visit to the Davies Alpine House will reveal a few more species, flowering in the more protective environment under the glass.

But out in the open, Cyclamen coum is now flowering on the Rock Garden at Kew. Although we haven't yet had much freezing weather this winter, this plant is very resistant to frosts, which seem to have no effect on the flowers or leaves.

The leaves of Cyclamen coum are rounded to heart-shaped and often have attractive silvery markings. The small flowers have short, wide petals that vary in colour from deep magenta to pale pink or white. C. coum has a wide range in the wild. It can be found from Bulgaria, across northern Turkey to the Caucasus Mountains and from south-east Turkey to northern Israel. Over this range there is some variation in leaf shape and patterning, and flower colour.

 In the wild C. coum grows in woodland, where it can create vast swathes of pink flowers. It can also be found on rocky ledges or on the sides of gorges, in gullies and along field margins.

It can sometimes be seen growing naturally with snowdrops, a combination that also looks great in the garden.

Cyclamen coum is easily grown in the garden, in sun or partial shade. The soil should be well-drained but not too dry in summer, when it is dormant. In the wild it often grows in areas where the annual rainfall is very high, such as north-east Turkey and western Georgia. It will seed around itself to form large colonies over time, making a beautiful sight in the winter months.

Another informative blog. I find the photos intriguing and the cultivation tips very useful. I have some C. coum in a north garden with a great deal of shade and damp soil. I didn't realize they are moisture loving and was all set to try some in a dry, south garden. Thanks to Richard's advice here, I will now switch to a different Cyclamen for that location.
