Best grown in acidic, moderately fertile, moderate wet, well-drained soils in full sun. Best flowering in full sun. Needs a sturdy support structure on which to grow. Can be invasive (rampant growth plus rooting surface runners). Needs regular pruning to control size and shape of plant. Can be slow to establish.
This Japanese wisteria cultivar is a woody, clockwise-twining, deciduous vine which typically grows 10-25” (often larger). Can also be trained as a multi-stemmed shrub or small tree. Features bright green, 12-16’ long, compound pinnate leaves (each with 15-19 leaflets) and 12-18’ long drooping clusters (racemes) of fragrant, pea-like, pale rose-pink-tipped-purple flowers which bloom from the base of each cluster to the tip in May as the leaves emerge. Flowers give way to pendant, velvety, bean-like seed pods (to 6’ long) which ripen in autumn and may persist into winter.
Though susceptible to a number of foliage-chewing insects and fungal diseases, none are significant. Considered a high maintenance plant, however, because of its need for regular pruning, its invasive tendencies which must be constantly monitored (particularly if grown on structures adjacent to buildings) and its vulnerability to late spring frost damage to flower buds.
Common Applications-
Excellent vine for large, sturdy, free-standing arbors, pergolas or fences. Can be grown up the side of buildings on large trellises or other structures. May be trained as a specimen shrub or tree.
