Hello, there. I bought a "Hummingbird Butterfly Mix" from Millington Seed Co. Amongst the flowers that I think I can identify are some gorgeous-looking little things that look like miniature snapdragons. They are magenta, purple, fuschia, pink, and yellow/purple. I think they are toadflax, so I sought some information on them. I found various sites that listed them as noxious weeds! One site even said they put out runners! Egads!! Does anyone have any experience with these?
