porcelain vine takes washington dc

porcelain vine is a horrible invasive plant in the eastern united states that smothers native plants and is sold in nurseries for its decorative qualities. sure, the berries start as an awesome turquoise and eventually turn to a more awesome purple, but this plant pulls down trees, people! in the dc area, it was actually recommended as a decorative verticle plantscape to cover sound barrier walls around the beltway: stupid paid advisor! birds love the beautiful berries and spread them throughout the area: now they threaten to take over rock creek park. only the weed warriors care.
