A garden ornamental that has made its escape into the wild, this vine has not yet become an invasive pest here, but is fairly common now in vacant lots and other unexpected places in the city. It covers itself with little white flowers (usually four-parted, but with a fair number of five-parted variants) in late summer, with occasional blooming branches up to frost. These plants were growing wild on a bank in Beechview, where they were blooming in early September.
