I grow persificolia (peachleaf) both white and blue. I love it. Seems to do nicely in sun or part shade. Self seeds abundantly but is easy to control and you can always collect the seed and put it where you want it - I just move the new plants! I dont start perennials from seed but with this kind of plant it doesnt take long to have too many! 3-4 feet high, looks best with a number of plants in a cluster. You might also try Canterbury Bells or Cup and Saucer Dont plant Glomerata - it spreads way to easily unless you want to cover a lot of ground quickly.

Here is a pic from my garden the white is to the left of the birdfeeder and there is some blue in the background.
