This Asian species, occasionally cultivated for its raspberries, was first collected in 1961 by C. W. Laskowski from “bluffs of Lake Michigan” in Berrien Co. without, however, a clear indication of whether escaped or merely persisting from plantings. It was found again, as a true escape, by W. S. Martinus in 2013 on sand dunes in Ottawa Co.

This is a distinctive species with the first year stems arching, often rooting at the tip, and covered with conspicuous, purplish glandular hairs as well as scattered small prickles. It is locally a significant pest in some eastern States.
