This arching shrub is an escape from cultivation that grows west of South Bend, Indiana, along the edge of a woods near the Grand Trunk Railroad. It also grows in roadside thickets at several locations: northeast of Lydick, Indiana along Pine Road, in LaPorte County on CR 350 N, and south of Syracuse, Indiana along State Road 13. It does not seem obnoxiously invasive at any of these sites, but the fruits are so prolific that it probably could become a pest. The specific epithet is also spelled "bungeanus." The leaves turn pink in autumn, but apparently not this year.
