A fantastic clump forming perennial that forms masses of sparkling star-shaped blue flowers with violet hues on a bed of long stalked rounded leaves. With its reliability, stability of colour and good resistance to pests and diseases it has earned the RHS Award of Garden Merit. Native to Siberia and Japan it is no surprise they do not like a wet winter and will do best in a sunny border or rock garden. They begin to flower in July and continue through into late August and can be planted in containers, but are most useful in the ground where the spreading foliage will produce a blanket of weed suppressing ground cover. Height 25cm. Supplied as UK-grown 5cm module plants.
