Plant details

An unusual shrubby member of a genus that comprises mostly climbers and scramblers. It is a native of Mediterranean limestone hills, and enjoys a hot sunny position in a rock garden, where fertility is fairly low and drainage efficient. The evergreen foliage is covered in silky silver-grey hairs, and the flowers start as pink buds which open into 2.5cm (1in) trumpets, with blush white petals marked with a central pink stripe. An attractive plant that benefits from annual pruning to maintain bushy growth down to the ground. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
