Succulent trailing foliage becomes a mass of blue, purple and white bells, each with an accentuated yellow and white throat.

Plants show great drought resistance and will look stunning all summer grown in baskets, containers or as a ground cover plant in hot sunny borders.

Sow February-May. Sow seeds on the surface of a good, free-draining, damp, seed or multipurpose compost. Cover the seed with a fine sprinkling of compost or vermiculite. Place container in a propagator or seal inside a polythene bag and place at a temperature of 18-20C (64-68F) until after germination which usually takes 7-21 days. Do not exclude light, as this helps germination.

Transplant seedlings when large enough to handle into trays or 7.5cm (3in) pots. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost, 30cm (12in) apart.
