In mid to late spring the creeping blueblossom and Siberian flag will do all the work providing a soft mixture of blues. They then make way for the delicious deep crimson flowers of the Scots heather which takes over where they left off, and carries on flowering right into the autumn.
Planting tips: In early spring the Calluna should be cut back to within 2.5cm of the old growth, and each year after the Ceanothus has flowered, reduce the shoots by one third to keep them nice and bushy. The Iris should be staked in early spring if you have a windy site, and make sure all the plants are fed with a specialist fertiliser for acid loving plants which contains additional iron.
