How about creeping phlox? I have some creeping phlox that's gone from a little 3" square to about 2 feet in 3 years here for me, so it should get huge for you guys pretty quick. And all my plumbago is in 100% full sun, no shade. Campanula? I love campanula.. I have some that are growing nicely and some that are kinda stunted. Another good thing I love is tradescantia, especially Sweet Kate. The Concord Grape gets too big, but my biggest Sweet Kate is only about 1' square, which is a nice fill size. I'm thinking about trying more Veronica (Speedwell) as well as that seems to grow very nicely for me here. And all my spireas stay about 1-2' square.. the oldest is.. 5? years old and is only 2' around. Guess that the difference between zone 9 and zone 5. Grow season here is, at best, 4 months long (May - Sept) before autumn starts up.
