Gorgeous quilts, Marion!
I would bind the first one with either the dark green leaf fabric or the fabric in the pointy/loopy Celtic frame around the center motif. I think more of the blue would be too much blue.
I did a BQ quilt such as yours (different flowers) and I outlined the flowers. In the large white spaces I did close straight lines, and left the frames unquilted. That worked well for my skill set.
