Geranium ‘Rozanne’ (Geranium x ‘Rozanne’) is a long-blooming, vigorous perennial valued for its profusion of violet-blue flowers with a bright white centre. The plant forms a spreading mound of deeply cut, medium-green foliage that provides an attractive base throughout the season. From late spring until frost, large saucer-shaped blooms appear continuously, making it one of the most reliable flowering hardy geraniums for borders and landscape use. It performs exceptionally well in cooler climates and is known for its adaptability and extended bloom time.
