An American cultivar with light blue flowers with a silver tinge, 17-20 cm across. 6-8 pointed tepals are wavy edged and have a purple bar along the midrib. Red-purple anthers on pink-white filaments. Flowers appear in May-June and again in August-September. It attains a height of 2-3 m and attaches itself to supports by means of twining leaf petioles. Useful for growing on fences, arbours, trellises, poles and other garden supports. It can climb over natural supports, such as deciduous and coniferous shrubs that don’t require hard pruning. It looks especially attractive planted against a dark background, next to yellow-leafed or yellow-flowered plants. Suitable for container growing.
