What it's good for, and what it isn't

'Rozanne' is useful for covering the ground beneath roses or softening the front of a perennial border, with violet-blue, white-centred flowers from summer into autumn. Leave room for its sprawling stems and water during prolonged dry weather to keep it flowering well. It grows in sun or partial shade but dislikes waterlogged soil.

Watch out for

Waterlogging, especially in winter, can damage the crown. Prolonged summer drought may make watering necessary, and sprawling stems can cover smaller neighbouring plants.
