Tall spires of tightly packed striking deep blue flowers with white standards make this compact & strong grower a real winner for early summer colour. The flowers rise above clumps of palmate foliage making it ideal for adding height & structure to the back of perennial borders & woodland edges. A distinctive hardy perennial that remains a cottage garden favourite. Flowers mid April-mid July. Height 80-90cm (32-36). Supplied in a 9cm pot.
