Japanese wisteria is distinguished by the many (15 or more) narrow leaflets making up each leaf and by long, relatively narrow flower clusters, the blossoms opening in succession. 'Kyushaku' is the probable name for a Japanese selection with bicolored, mostly pale lavender flowers in incredibly long tresses, alleged to reach nearly four feet (they have been about half that in containers). Sun, reasonably well drained soil, moderate watering during active growth. Wisterias tolerate a surprising degree of summer drought. Hardy to 0 degrees F or below.
