A Japanese cultivar with deep violet double flowers, 10-12 cm across. Numerous, irregularly elliptic, curved tepals have a nicely contrasting silvery underside. Violet anthers on whitish filaments. It flowers from the second half of May through June and can repeat the blooming in August and September if given the trimming off the faded flowers. Late summer flowers are sometimes single. It attains the height of 1,5-2 m and attaches itself to the support by means of twining leaf petioles. Useful for growing on trellises, poles and various garden supports. It can climb up natural supports such as deciduous and coniferous shrubs or dwarf shrubs that don’t require hard pruning. It looks at its best against a light background. Good for container-growing.
