(aka: Geranium 'Gerwat'; Plant Patent 12,175 Expired) Geranium 'Rozanne' is an amazing geranium that has proven to be an outstanding garden performer...hence, it is one of only a few hardy geraniums ever patented. She 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 Geranium himalayense x Geranium 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 her do her thing in your garden. Maintenance: In the ground, this superb selection is a very low maintenance perennial. The only thing you might want to consider is to cut the plant to the ground in fall as part of your garden cleanup. The basal rosette will remain evergreen, re-sprouting in spring. Rozanne geranium is quite a scrambler and can overtake smaller adjacent perennials, so there may be a time in the middle of growing season you need to cut it back, which is no problem. Growing Conditions: 'Rozanne' isn't particular fond of shade or saturated soils, but there isn't much else it doesn't like. It responds quite well to rich, organic garden soils. Irrigated gardens are fine, as are all droughts, except those that may be extended with temperatures over 90 for weeks. In this case, some extra water will be appreciated. Garden Value: You'll find this a superb plant to weave in and out of other perennials with no detrimental effects on their neighbors. The lavender blue flowers are produced from spring through fall, for an amazingly long floral show. Natural Impacts: Bees are the dominant pollinator for hardy geraniums.
