Plant details

Also known as C. mauritanicus, this tender rock bindweed is a native of north Africa and a popular trailing subject (strictly, prostrate climbing) for warm sunny positions. It has become a familiar ingredient of hanging baskets and containers, but was grown in the past as a summer subject for rock gardens, where the stems could bake on the stones and root wherever they touched the soil. By late summer the bushy plants are smothered in clear, soft blue trumpets. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
