I pulled a singular black swallow-wort plant (Vincetoxicum nigrum) from my yard last week. It had already flowered and developed its identifying cylindrical seed pods. I thought it must have been dropped by a bird somehow but read that the seed pods open up like milkweed pods and its seeds are scattered by the wind. In fact, it’s a relative of milkweed. This vine plant can take over an area, much like Asian bittersweet. However, because it’s a relative of milkweed, Monarch butterflies might lay their eggs on it and die. I put it in the trash.
I enjoy bicycling around the area and decided to scan the roadsides for this plant. I never saw it until walking close to my house and there it was on the roadside. You’ll have to read about it. Places in New York State are covered with it and it’s spreading. If you happen to see it in your yard, I suggest you don’t let it spread. Thanks!
