Nicely rounded shrub to 60cm x 60cm with massed spikes of purple-blue flowers in Spring. Dead head the flowers once the flush of flowers has finished and you will be rewarded with another flowering in Autumn. Prefers full sun in well drained soils. Drought and frost hardy but we recommend summer water in hot, dry districts. Stunning in massed plantings and borders and also suitable for containers. Prune back after Autumn flowering finishes.
