I found both of these plants next to a shed in the Adirondack Mountains in NY. One has small, pink flowers , each attached to a tube where the seed is, and the other has large, blue/indigo flowers on the same tubes. Both have roundish opposite leaves. Both flowers have 5 petals. Will post the rest of the pictures.
