Deb K. sent me a text with some information from Fine Gardening magazine. She sent a link to the article for sharing here. I think you will find it very interesting:
As well, she sent Jennie’s response, to her sending the article link to her. It includes which ones are in our demo gardens: Jennie’s comment:
” Interesting! Did you think of me when you saw the pawpaw flowers? We have most of those in the demo gardens. Pipevine and that genus of wild buckwheat are not native to MI, although some pipevine has escaped cultivation and “gone wild” in the state. In the demo gardens we have a relative, wild ginger, and a closely related butterfly, the spicebush swallowtail that is similar in appearance to the pipevine swallowtail. (and we have spicebush). The weed called wild buckwheat around here is in another family related to buckwheat, but as its latin name, Polygonum convolvulus suggests, it looks more like a morning glory (Convolvulus), except for the flowers. There is some of that along the chainlink fence at the demo gardens but we try to keep it down.”
