A few more pics might help and an indication of size, but as ladybird says, most of us aren't familiar with US plants.
I'm finding it hard to believe that those 2 are the same plant tbh.
The top one resembles Achillea grandifolia in leaf, that has a strong smell. It's not a shrub, though could be mistaken for one if you only see it in full growth.
The second is not an achillea of any sort
