This East Asian shrub does not seem to have spread far from cultivation in eastern states. In Ky. there are colls. from GRAN (KNK), JEFF (KNK) and WHIT (EKY) that may represent true escapes (M; Clark et al. 2005), but no reproducing populations are yet documented in the wild. A coll. from LYON (APSC) was a plant persistent after cultivation.
