I have a few thoughts already, of course.
I'd like to put in bleeding heart (Dicentra spectabilis) and columbine (Aquilegia) in the section behind the sidewalk, which both remind me of the gardens at my childhood home. I could see the bleeding hearts near the front door and the columbine spread out between there and the driveway. At the very least, we'd need another low groundcover-y plant to make the space look full.
To the left of the front door, I'd like to put something really striking. In my mind I want sunflowers with Zinnias in front, but I can't offer as much sun as they need. What would you recommend for bright, cheerful, rainbow-colored blooms in partial-to-heavy shade?
And near the driveway, I think I'd like to put in a rosemary plant. I'm hoping that the heat coming off the brick and asphalt will help me push its zone a bit.
