dog-strangling vine, Vincetoxicum rossicum
Dog-strangling vine's quarter-inch flowers are certainly an interesting sight. But not a welcome one. This invader is a twining vine that can seriously interfere with the growth of other herbs. In Michigan, it has only been found in counties with major freeways. One can picture its wind-born seeds hitching rides, starting on coasts and spreading inward along the arteries. Ugh! Reminds me of the strange unidentified patch on my elbow, which has also been spreading. Damn the invaders! Dog-strangling vine, also called European swallow-wort, has been reported from CT, IA, IN, MA, MI, MO, NH, NJ, NY, PA, BC, ON, and QC. Waterloo Recreation Area, Washtenaw Co MI, 5/28/12.
