Went to HD yesterday looking for milkweed and was shown some plants that turned out to be butterfly weed. It was so hot I really didn't pay attention to the difference. They look nice and healthy but just reading about them will have to change where I was going to put them. Since they don't get as tall as the milkweed plant I have. My lone milkweed has had about a dozen cats on iit at one time or another. They are there one time and then gone the next. Don't know what's happening to them.
