Very interesting article. I have a wild morning glory growing all over my yard. When I saw the leaves of this milkweed, I got a little scared that I had it not morning glory. But after reading the article I know I have a morning glory. But I'm always out looking for interesting plants or seeds for my garden and I know now not to touch this plant.
I hope you have ONLY native species of morning glory. The milkvine is a very important native species for pollinators. Some popular but non-native morning glory species are worthless to our native pollinators.
