Don't wait for autumn to plant this gorgeous, little plant. Get it into position early so that it can grow, spread and really establish before the fireworks start in late summer.
Masses of deep Oxford blue flowers appear towards the end of summer and given a little shelter will continue until late autumn. The hairy dark green leaves start to turn rusty red and orange as the blue flowers appear making a cheerful display for containers, path edges, dry walls or slopes, long after most plants have faded. It prefers light, moderately fertile soil with good drainage in full sun and should be cut back in late autumn. Tidy up any frost damaged growth in spring.
It will spread by underground rhizomes and in time will form a dense mat.
