Geranium ‘Gerwat’ ROZANNE

Geranium Rozanne is a hybrid in the family Geraniaceae, the result of a cross between Geranium himalayense and Geranium wallichianum Buxton’s Variety. Hybrid Cranes Bills or cranesbill are very popular in Europe. Members of this genus should not be confused with the common annual geranium of summer gardens, which are actually in the Genus Pelargonium. Hardy geraniums or cranesbill geraniums get their common name from the resemblance of their seed-pod shape to that of a cranes bill or beak. Blooms of Bressingham first introduced Geranium Rozanne at the 2000 Chelsea Flower Show.
This magnificent new (and true) geranium is a big plant with bright blue flowers that bloom all summer long, showing great color until frost. This is one of the best recent hybrid forms of Cranesbill, excellent for long-season display. It forms a compact 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.
Geraniums make great edgers and are wonderful for use under leggy plants, like roses. A free-flowering clump former, like ‘Rozanne’ is especially nice at the base of an entry gate or on the corner of a garden border. ‘Rozanne’s’ heat tolerance also makes her a good choice for rock gardens and containers or window boxes. The brilliant blue is all the more electric when paired with yellow flowers like coreopsis, black-eyed Susan and goldenrod.
Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Prefers moist, organic soils. Best grown in full sun with some afternoon protection. ROZANNE has exceptional heat tolerance, and generally will bloom throughout the summer. If flowering stops and/or plant foliage depreciates in the heat of the summer, plants may be cut or sheared back to rejuvenate, shape and/or encourage additional bloom. Side stems may be removed or trimmed at any time to control spread.
Geranium Rozanne thrives in full sun to partial shade in moist, well-draining soil. It is hardy in USDA gardening zones 5-8. To maintain peak bloom and foliage appearance simply shear back old foliage in late summer to 3 inches.
