Spikes of clear blue flowers rise above the clumps of lush green leaves in spring and last a long time in flower. Great for naturalising and a lovely cut flower.
Likes any free draining soil in a sunny or slightly shaded spot. Great for containers. Flowering in spring, height and spread 75cm by 25cm.
Add sharp sand or grit if tyhe soil is liable to stay wet in winter. After flowering allow fading leaves to die back naturally.
