Sorry about the bad photos... It's a woody shrub with a main stem that spreads to 3-4 outward branches once it gets 3' tall. The stems are about a 1/4 to 1/2 inch thick at the base. 3-4' tall. Pink flower clusters in May (zone 5). Part shade. Leaves are like a wisteria, but rounded and not a vine. Looks like it has runners underground, or perhaps babies from the main plant.
