Rozanne® hardy cranesbill is a patented hybrid cultivar that is a result of crossing selections of different geranium plant species. It has green cut-leaf foliage and violet-blue flowers that continuously bloom from late spring to early fall. This geranium is drought-tolerant once established, but prefers average, well-drained soil in full sun to partial shade. This low-growing perennial is a great addition for border gardens and attracts butterflies and bees throughout its blooming season.
