When I was visiting the RHS garden at Harlow Carr in March I was delighted to see cyclamen coum growing quite happily at the base of a living hedge. Although they are hardy, I am not sure just how hardy they are. It's been a relatively mild winter in my area of England and the Harlow Carr gardens, in North Yorkshire are a lot more sheltered than my own garden in West Yorkshire, which is about 870ft or so above sea level.
