Wisteria brachybotrys Okayama (Silky Wisteria)

Strongly scented, award-winning Wisteria brachybotrys 'Okayama' produces masses of hanging sprays, up to 4-6 in. long (10-15 cm), of fragrant, pea-like, pale lilac flowers with a large and conspicuous white spot. Opening from rich violet buds, they bloom early in the season in late spring. The flowers are followed by attractive, velvety, bean-like pods, 8 in. long (20 cm), which ripen in late summer and may persist into winter. Particularly attractive is the dense foliage of exotic-looking, pale green, pinnate leaves which consist of 11 downy leaflets and turn rich golden-yellow in fall. A beautiful choice for a house wall or large pergola.
