Maybe Solanum carolinense. I get them here quite a bit in Western NY. I don't see any thorns on this one which would be unusual for Solanum carolinense but we could not see the underside of the leaves - one of its thorniest locations. This is a common weed in one of my vegetable beds and I find quite a variety in their thorniness. Also the thorniness varies with age too. Young plants seem less thorny than the veterans coming back from roots I haven't managed to pull completely out. Compare and see what you think.

Looks like my South African Foxglove.....Ceratotheca triloba....expect mine grew to about 4.5' tall. If so they are an annual in our zone.

Nice. Spilt Milk is a favorite with me too. I think you are right on with your two ids.

Funny thing is this garden (on a slope in my front yard) used to be a shade garden - a large tree (mullberry) shaded it effectively. A couple of years ago that tree came down so now its mostly sun. I had planted a bunch of shade loving plants there - things like hostas, ferns, etc. Now those plants have exploded in size, though I have to be careful in making sure things are well watered. These pulmonarias are spreading pretty quickly now, on some level I have to keep an eye on them so they don't invade other spots so much. Thanks for input! Bob
