A very pretty double-flowered Wisteria, award-winning Wisteria floribunda 'Violacea Plena' (Japanese Wisteria) produces masses of hanging clusters, up to 12 in. long (30 cm), packed with lightly scented, violet-blue, double flowers. They appear in late spring or early summer along with the leaves. Equally attractive is the dense foliage of bright green, pinnate leaves which consist of 11-19 lance-shaped leaflets and turn brilliant butter-yellow in fall. This Japanese Wisteria is a real show-stopper.
