Neat clumps of narrow grass like leaves are grey/green and are topped by a wealth of small very attractive purple/pink flowers in clusters. Likes well drained soil. Height to 50cm. An excellent plant for container growing, or in the garden. Can be cut back to 3cm in autumn and mulched with peat. Plant in a sunny position. This plant is also suitable for the Pondside/Bog garden. Place around the edge of a pond, providing soil is damp and not waterlogged. Alternatively plant in damp areas of the garden.
