Salvia?

Don't think Salvia, the foliage would be arranged decussate(?), like a cross ( looked from above).
Could be joe py weed (Eupatorium), is there any near by?

kind of early for joe pye to be budding up>>and don't think veronicastrum. hmmm

I wondered about both of those, also, but didn't think they fit, either. I'd wait until they prove themselves by blooming. You can always deadhead to keep them from reseeding. And a shovel will get rid of them if they are too big to yank. Maybe someone can still ID them for you. Good luck.

Looks like it's spreading pretty good too. Might be a good plant to keep an eye on!
