You might try a single flowering fuchsia triphylla like 'Gartenmeister Bonstedt' or Fuchsia boliviana also likes a little shade. Not too sure if they mind acid soil.

Actually it sounds like a nice place for rhodos.

Haven't had any luck with fuchsia in our long hot humid summers here. And the rhodos only bloom in the spring. So will have to find something else. But aren't fuchsias gorgeous! Such intriguing blooms!

You could consider clethra or sweetspire. This is a sweetly fragrant, summer blooming shade tolerant shrub that hummers love. Other possibilities are loropetalum, hardy fuchsias (not the foo-foo annual hanging basket kind) and Cape fuchsia, Phygelius species.

Cleome spinosa (Spider flower). My hummers love 'em. It grows 5-6 ft tall, loves the heat & humidity of the South, and blooms from early June until the first moderate frost. It will reseed like a weed. (I have some seeds if you want them.)

Black and Blue salvia would be real good. It blooms early and then until our first frost here in southeast Alabama. A big favorite of hummingbirds.

If you lived close enough to me I could give you plenty B&B in the early spring.

I really like the cleome too but in our zone the B&B has a longer bloom time. I do not ever want to be without either.
