In an earlier version of this article, we misidentified this as the native Virgin’s Bower (Clematis virginiana). That is a very similar relative; this plant is the Asian Autumn Clematis (Clematis terniflora), which is becoming more and more common along fences and twining through hedges in the city.
For a description of the species, see the Clematis terniflora reference page.
