This amazing new geranium has proven to be an outstanding performer...hence, it is one of the only patented hardy geraniums. G. 'Rozanne' was discovered in 1990 in the garden of Donald and Rozanne Waterer of Somerset, England, and released by Blooms of Bressingham. This sterile hybrid of G. himalayense x G. wallichianum 'Buxton's Variety' makes an 18" wide clump, topped from June until frost with large 2.5" blue-violet flowers. We think you should let Rozanne do her thing in your garden. Pot size: 24 fl. oz (709.77 ml)
