Pardon my fingers; the wind was blowing and I was trying to steady the plant enough for a photo. There is just one of these plants all by itself in this field, but it’s considered highly invasive, so I wonder if there will be more next year. An unusual color. A twining vine. Milkweed family. Introduced from Europe in the 19th century.
Pale Swallowwort, Dog-strangling Vine (Cynanchum rossicum)
