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'.
