Porcelain berry is among an array of invasive vines to swallow Pittsburgh, along with wisterias, wintercreeper, wild grape, bittersweet, mile-a-minute, and English ivy. It is these same vines that strangle trees, drag them to the earth, and provide channels for pests and disease to their branches. In winter, the Deads writhe their way around that turret, up the house’s sides, and through the bramble of the house’s yard. Think of the vines that swath Nassau Hall, the Old Graduate College, East Pyne, Holder, and Foulke. The vines on Nassau Hall, on the other hand, will remain as green and lively as the ivy on the houses I walk my dog past in Pittsburgh.
