My experience with shrubs is pretty slim, so I don't have any advice for you except this - the Mo Botanical Gardens plant finder is very very helpful. Plug in your requirements and you'll get just what you need:

Besides all the encyclopedic info, comments from users are always pertinent, as well.

What have you tried so far? That isn't very much sun but a shade loving shrub might not like the afternoon midwest heat.
Annabelle hydrangea will take more sun than other hydrangeas and one of my favorites. I have one on the northwest corner of my house and it doesn't mind the afternoon sun. It's also close to a downspout. I think it would do well in your first spot.

Still trying to think of something a little smaller for the second spot.

Thanks for the referrals. I love the botanical gardens website finder!!!

Christie, how big is your annabelle?

My Annabelle is 4' x 4' right now but I think when it's in full bloom later this summer, it will be at least a few inches taller and wider.
Mobot has a "Plants of Merit" list too that is wonderful especially since you live in the same area and some of their plant descriptions have a link to "bloom data" that shows when and how long the plant was in bloom. They have a great website.
