Campanula persicifolia perhaps.

Yes, that was my guess as well.

Leaf margins aren't crenate. Myosotis laxa?

compare to Penstemon basal foliage?

I compared to P. hirsutus and P. digitalis, and their leaves look spathulate, while these leaves are more linear/lancolate. One other possibility is Coreopsis lanceolata. That species seeds around very well.

Shooting from the hip, the basal foliage sure looks like my silene virginica.

It resembles so many things, probably we will have to wait for the flowers.
