An unusual shrubby member of a genus that comprises mostly climbers and scramblers, Convolvulus cneorum is a native of Mediterranean limestone hills. Its evergreen foliage is covered in silky silver-grey hairs, and the flowers start as pink buds which open into 2.5cm trumpets, with blush white petals marked with a central pink stripe. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
Grow Convolvulus cneorum in well-drained soil in full sun, ideally in a rockery or similar situation. Prune hard annually to maintain bushy growth down to the ground.
