A Japanese cultivar with lilac-blue flowers, 15 cm across, composed of 6-8 petals. The stamens have pale yellow anthers on long creamy filaments. Flowers appear from June to August. It can grow up to 2-3 m high and attaches itself to the support by means of twining leaf petioles. Useful for growing on fences, arbours, trellises, poles and other 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 particularly lovely against a yellow background.
