Japanese variety with conspicuous, intense blue flowers of 15-17 cm in diameter. 6-8 elliptic tepals with slightly wavy edges overlap to 1/3 of the distance from the base. Pale yellow anthers on white filaments. The flower crop is the most abundant in June and early July, and continues till mid-August. It grows up to 2 m high and clings to its support by twining leaf stalks. Useful for growing on fences, arbours, trellises, sticks and other garden supports. It can climb over natural supports, such as deciduous and coniferous bushes or dwarf shrubs that don’t require hard pruning. It looks lovely against a light background or when combined with yellow-leafed or yellow-flowered plants. Suitable for container growing.
