Are you referring to the plant with the dark splotches on the leaves as orange butterfly weed (Asclepius tuberosa)? Mine doesn’t look like that at all, that plant is not Asclepias but looks like Persicaria, however, I‘m no expert.

The two plants in your picture are not the same.

I want to say that last summer one of those two had the orange flowers of Asclepias. My girlfriend bought the house in June of 2019, so everything is still a guessing game. And I'm not there right now, she's just sending me pics...

They look like 2 weeds to me.

Well, there may have been Ascelpias tuberosa there at one time, but it is not there now.

Sorry, bit neither of the larger plants is Butterfly Weed. Bottom is a Smartweed, Persicaria species. Top looks like a weedy Erigeron.
