Looks like a variety of hibiscus.

Appears to be a Rose of Sharon (Hibiscus syriacus).
Rose of Sharon. I have a good many of them in my yard also. Bumblebees love them, my honeybees don't pay much attention to them.
I have a similar bush in the back yard, the leaves are the same but the flowers are pink/purple and more frilly. The honeybees to work it pretty good, but I think that might be a function of dearth, not preference.
Great photos! Thanks!
I wonder if all that powdery pollen keeps mites off like powdered sugar does?

I agree with Coyote. It looks like a hibiscus, but can't really tell without seeing the whole plant.
