Geranium 'Rozanne' (Cranesbill Geranium)

Selected as the 2008 Perennial Plant of the Year. This is one of the best recent Cranesbill introductions, excellent for long-season display and leagues better than older garden forms such as ‘Johnson’s Blue'. It forms a midsized mound of deeply-cut green leaves, bearing loose clusters of bright violet-purple cup-shaped flowers starting in early summer. Flowering can continue for weeks or months, particularly in regions with cool summers. Performs well towards the front of a border, also excellent for massing or in mixed containers. Prune back by half to rejuvenate, if flowering lags during hot weather: this is very seldom required with this free blooming selection, however. Often gives good bronzy fall colour

USDA Zones: 4 - 9
