Have you seen this invasive weed in your area? Black swallow-wort (BSW) is an aggressive weed that’s harmful to native plants, butterflies, birds, and more. BSW has shiny green leaves that come in pairs, thin green pods, and small dark purple flowers that grow in clusters.

BSW can often be found around fences and shrubs in late May and early June. If you see BSW, dig it up by the root and seal it in a trash bag.
