Wisteria floribunda ‘Macrobotrys’ (Japanese Wisteria)

Noted for its excellent fragrance and voluptuous floral display, award-winning Wisteria floribunda ‘Macrobotrys’ or ‘Multijuga’ (Japanese Wisteria) produces masses of extraordinarily long hanging clusters, up to 40 in. long (100 cm), packed with pea-like, lilac flowers with dark violet markings. Blooming in late spring or early summer, when the leaves open, the flowers are followed by attractive, bean-like pods, which ripen in late summer and may persist into winter. Equally attractive is the dense foliage of large, dark green, pinnate leaves, which consist of 15 lance-shaped leaflets and turn brilliant yellow in fall. This Japanese Wisteria is a strong-growing climber with twining stems of great beauty. A real star in the garden.

• Can be grown against a house wall, arbors, pergolas, trellises, or fences or trained as a free-standing half standard. It must be sited and trained on sturdy structures which will be able to support the heavy weight of the mature Wisteria. Grow this plant around patios where the flowers can be enjoyed.
