Cyclamen rohlfsianum

Cyclamen rohlfsianum

Cyclamens comprise of a group of very distinct species native to parts of Europe, western Asia and North Africa. C repandum, hederifolium, purpurascens and coum were certainly in western European gardens by the 17th century. By the early 1900s the majority of the species had been described.Sounds fairly straight forward. doesn’t it? Well actually..no the correct identification of species is a very challenging task. Certainly a work in progress for us.

Cyclamen can survive brief periods at temperatures below 0 degrees. Weather buffers of trees, shrubs, buildings, amount of moisture, sun, etc. can make a difference in successfully growing cyclamen in severe cold. It is good to keep in mind that winter is their growing season when they need light and moisture. Having said that, there are a number of species that survive quite well. These include hederifolium, coum, purpuracens, cilicium, pseudibericum and repandum. C.hederifolium and coum being the easiest to grow.

Cyclamen are ideally suited to growing in a shaded rockery or naturalised in the light shade of woodland borders. Planted in beds of their own they will create a colony of amazing color. Hardy cyclamen are one of the few flowering plants that will grow in the dry shade, one of the most challenging spots in any garden. Cyclamen roots are noncompetitive and can be planted among the roots of trees and large shrubs, both deciduous and evergreen. Trees and shrubs provide protective shade, buffers cold winter weather, and their roots absorb excess moisture improving drainage.

Sandy to clay soils are acceptable but should be well draining and loose with grit, compost or mulch. Wet and soggy soils with poor drainage will cause tubers to rot. Raised beds are proper if poor drainage can not be modified with the addition of mulch or compost. Fertilisers are not necessary but adding some blood and bone won’t hurt. A layer of compost or mulch applied over the dormant tubers in summer is all that may be needed to provide nourishment while also discouraging weeds. Mulch can also preserve and even out the supply of moisture.

Description and Distribution:
This is a very distinctive species and quite tender; even a light frost burns its foliage. It is native to Libya. The flowers are unique in that the cone of stamens protrudes well below the mouth,  somewhat resembling a dodecatheon. Flower colour can vary a bit from pale to deeper pink.  The leaves of this species are coarse, wider than long, and lobed, with a coarsely toothed margin; they can be banded with cream or silver markings. It is the one species that appears to benefit from a totally dry dormancy.
