I want to say Bug Bane, Cimicifuga racemosa, but I'm not sure the bees like it yet. Hasn't bloomed yet.
I have some Blazing Stars, Liatris, planted in partial shade under a tree. The bees love them. Liatris in shade tends to bloom a month later than it would normally.
Joe Pye weed, Eupatorium, can be planted in partial shade too, it actually grows taller in the shade but has a higher risk of falling over. So prop it up. A few Eupatoriums are actually compact in size too.
Aster cordifolius, Aster divaricatus, and Aster macropbyllus all love shade. I don't believe I own these but I know bees enjoy Asters very much.
