No, this isn't my garden! I was at the RHS garden in Harrogate today at Harlow Carr and this incredible display of heathers is near the entrance. I'm not normally a fan of heathers and conifers but can't deny this is a fabulous display. Yes these are all named varieties. They are used throughout the garden in the winter borders and come into their own at this time of year.
Good luck with your rock garden!
Best wishes
