One of the best pale blue Wisteria cultivars, award-winning Wisteria floribunda 'Lawrence' (Japanese Wisteria) produces stunning tresses of sweetly scented, pea-like flowers, up to 20 in. long (50 cm). They are densely packed with pale blue-violet blooms (up to 170!), adorned with deeper violet-purple keel and wings and a greenish-yellow blotch. Blooming in late spring or early summer, 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 fresh green, pinnate leaves which consist of 13 to 19 lance-shaped leaflets that turns to clear yellow in the fall. Highly floriferous, long racemes, pale blue flowers and lovely fall color make 'Lawrence' an excellent choice for the garden.
