(Blue star). An attractive plant that is useful from spring through to autumn, hardy to frost and tolerates both damp and dry conditions. Slowly forms a clump of fairly upright stems clothed in willow-like leaves, each topped in spring with clusters of gorgeous blue starry flowers. The foliage turns a lovely shade of bronzed yellow in the autumn. Full sun to part shade. Eventually gets to 80cm H x 70cm W. 9cm pot.
