Thank you very much, to everybody that answered my weed i.d. question. But now I have to decide if what I believe is physalis virginiana is a native wildflower or a potentially invasive weed! I think I will let the plant's fruit develop its full fall color and then remove them before any seed can fall to the ground. Now I have another weed I would like identified, if possible. This one is very similar to common motherwort, but much more prolific. Last year and especially this year it has spread to an unbelievable extent! I don't think it develops the really dangerous spines of the common motherwort, although it has the same formation of "flowers along the stem. Here is a photo of the leaf of each of them
The leaf on the left is the horrendously invasive one, and on the right is common motherwort.
Leaf color not as dark as the photo.
