This is an easy, carefree geranium; a strong grower with a sprawling habit like 'Dilys'. The finely cut foliage is accented by large (for a geranium) blue-purple flowers with pale blue eyes which cover the plant from early summer to frost. 'Rozanne' was discovered by Donald and Rozanne Waterer of England as a naturally occuring hybrid of Geranium himalayense and Geranium wallichianum 'Buxton's Variety'.
Clump-forming perennial with dense spikes of sulphur yellow in June resemble Baptista or lupines. Clean, compound foliage is attractive late into the season. Very durable and long lived once established. Beautiful cut flower.
