Bergenia cordifolia 'Bressingham White' is a clump-forming evergreen perennial and is very useful ground cover. Unlike some of its relatives, 'Bressingham White' is a tasteful blush pink rather than a lurid candy floss colour carried on rhubarb-red stems. Even people who say they can't stand elephant's ears will like this cultivar. It makes around 45cm in height and spread and will tolerate sun or partial shade. I use them all the time when I'm designing gardens.
Geranium macrorrhizum 'White-Ness' - An undemanding, semi-evergreen ground cover with attractively divided, aromatic foliage, that may take on seasonal colour in autumn. In early to midsummer, this rhizomatous perennial will also produce an abundance of small, pure white flowers. A very pretty perennial for the woodland floor or for areas of naturalised planting.
Plants for shade: elephant's ears (Bergenia cordifolia 'Winterglut'). Lush, deep-green leaves emerge in spring and turn red in autumn. Grow it in partial shade. Read more about them on our website http://www.gardenersworld.com/plants/bergenia-x-schmidtii/1225.html
