Black Swallow-Wort: Unwanted in Newton

Armed with seed pods that look like chili peppers, shiny green leaves that come in pairs, purple star-shaped flowers, and grappling spaghetti-like roots, this invasive non-native vine threatens monarch butterflies and songbirds and displaces native plant communities vital to insects, birds and other urban wildlife. Known to frequent chain-link fences, it is also found in woodlands and shrubs throughout Newton & surrounding neighborhoods – it has invaded and is spreading fast!
