Plant details

This architectural rock plant is an interesting addition to any garden, with red leaves that grow in fleshy rosettes. The purplish flowers are produced in early summer. It can be grown outside in very dry spots but is best grown in pots of free-draining compost. It's an excellent choice for a rock garden or stone trough. Excess moisture can damage the plant in winter and it will benefit from being brought into the shelter of the greenhouse or cold frame. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
