Also known as Convolvulus mauritanicus, this tender rock bindweed is a native of north Africa and a popular trailing plant for hanging baskets and containers. It's also suitable for growing over walls and in 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, attracting a wealth of pollinating insects. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
Grow Convolvulus sabatius in well-drained soil in a sheltered site in full sun. Take cuttings in summer or dig up plants and move them inside over winter for use next year.
