’Rozanne’ was bred in the garden of Donald and Rozanne Waterer in Somerset, UK and first discovered in 1989. It appears to be the result of crossing Geranium wallichianum ‘Buxton’s Variety’ with an unnamed selection of G. himalayense. Eventually it came to the attention of the renowned Blooms of Bressingham Nursery and was subsequently increased and introduced to gardeners in Europe and North America. ‘Rozanne’ is protected by US Plant Patent #12175: unlicensed propagation prohibited. Registered with the Canadian Ornamental Plant Foundation.

Hardy Cranesbill Geraniums should not be confused with the orange, pink, white or red-flowered tender annuals that gardeners everywhere know as Geraniums, more correctly called Pelargonium. Hardy Cranesbill Geraniums come back year after year outdoors, though hardiness varies depending on the particular variety.

• Hardiness: USDA Zones 5 to 9 (survival in Zone 4 appears good when there is reliable winter snowcover).
• Size: 12 to 20 inches tall (30 to 50cm) and 18 to 28 inches wide (45 to 70cm).
• Light exposure: Full sun to half day sun or bright part shade. In hot, humid summer regions some protection from afternoon sun is advised.
• Soil: Average to moist, well-drained soil.
• Uses: Excellent in the front to middle of a perennial or mixed border in small to medium sized groupings but also good for large massed plantings as a groundcover. ‘Rozanne’ has a mounding to slightly sprawling habit that is ideal for knitting together neighbouring plants. This habit also makes it useful for spilling from containers, window boxes or raised planters. Around taller specimen plants such as ornamental grasses, daylilies, hydrangeas, roses or lilies, ‘Rozanne’ is a great filler that will provide colour literally for months on end. Why look at bare soil when ‘Rozanne’ can provide the perfect touch!
• Unique Qualities: the large violet-blue flowers with purple-violet veins and small white centres offer non-stop flowering from late spring/early summer until hard frost. It has one of the longest flowering periods of any of the Hardy Cranesbills with no deadheading or midsummer pruning required.
