Shrub for shady area

I have an area on the north side of my house that I'd like to plant some shrubs. Something that will get between 3-5 feet or so. Flowers would be a huge plus, or evergreen, pretty fall color or some other attribute.
I thought about hydrangeas but I dont know if they need sun to bloom? I get summer temps into the high 90's or 100, and our winters get to 0. I am in zone 6. I would also prefer something that did not get an invasive root system. I bought some weigelas but I am afraid they need more sun? Azaleas would be nice, but they aren't large enough. I'm out of ideas, any suggestions, please!

Off the top of my head:
Hydrangeas can bloom in bright shade, but bloom better with more sun.
But the shade would help protect them from the afternoon wilting sun.
There are azaleas which will get 3-5ft tall,
so I don't think the height requirement eliminates them.
Several viburnums do well in shade, but they would all be too big,
even the supposedly 'compact' ones.
Pieris is also a possibility, but I haven't had much success with them around here.
There's a short little deutzia called Nikko which is shade tolerant and blooms nicely.
But it's only 1-2ft tall.
There's also a cute little osmanthus called Sasaba, which does well for me in a shady spot.
It's mainly a foliage plant; I think it's very cute.
Then, of course there are boxwoods, including some nice variegated options
which do fine in bright shade.
Carol Mackie or Briggs Moonlight daphnes do well in shade also.
Finally, there are several dwarf nandinas which do fine in shade; nice fall color.

I have an old fashioned basic Weigela planted under maples etc, dappled all day shade and it blooms pretty well.

Dirca palustris is a dandy little native shrub that likes cool soil and is very shade tolerant. At my old place I planted one tight against the north side of garage. It's now about 4' tall and 5' wide. Dainty yellow flowers in early spring with warm golden-yellow fall color. It's supposedly difficult to propagate, and it can be difficult to find and expensive to purchase.

I also had Calycanthus floridus 'Athens' in this location and it did quite well. It may get too big for what you're looking for, but it has interesting and very fragrant flowers.

I've become smitten with Tsuga canadensis cultivars, which are numerous and available. In addition to a seedling, I've got Moonfrost, Gracilis, and Jeddeloh, all of which are in moderate to heavy shade and doing quite well. Plus, the deer have left them alone. Knocking on wood...

The Oakleaf Hydrangea does well and blooms in shade and also the Fothergilla for flower spikes in spring and great foliage in the fall. The Maple Leaf Viburnum also delivers a lot for a shade plant.

Well I think I will use hydrangeas and some nandinas. I bought a couple of rhododendrons on clearance, hopefully those will grow in shade for me. Thanks for your suggestions!
