Vinca Vinca Vinca!
Great ground cover, pretty little purple flowers, survives in our clay soil in the shade. I would also add daffodils this fall. Naturalizing daffodils, so you don't have to replant for awhile. And, I would definitely do the hostas (maybe a light variegated type) coming up out of it... Maybe with Astilbe, and, and and... (I'm going all psycho border collie here) and, and, the impatients are perfect!
Whatever you do, don't do the blue glass orb. You won't see anything else.
Okay! If I can tell you what to do again, let me know! I love telling people what to do! lol
