Ann, I was going to suggest a Miss Kim lilac (honest..lol), but was unsure just how much sun it would receive. Where in the pic were you thinking of placing it?
Although they do best in full sun, if they receive at least half a day of sun, it should do okay. It probably won't blossom as profusely, but if you want one, go for it!!
You mentioned that you like hydrangeas. They would work well for you with your partial shade, and give you the flowers you want. Here's a link to some hydrangeas you might want to consider,

It's nice to see you here, Diane!
Now I'm wondering how far apart you and Ann live from each other?
Diane, have you contacted a landscape architect to help you with your grounds? Your lot is quite large, isn't it?
Diane, I've only seen a few log homes, and nothing as spectacular as yours. To me, your house is nature, built from nature, and in MHO, the grounds should be a extension of that. Or is it the other way around?
Anything too manicured would detract from the setting and the style, of your home. Plants/trees/flowers that are indigenous to your area would work best. Please remember, that's just my feeling about it. You of course, are free to do whatever pleases you!
The following article explains what I'm trying to get across. You may have already read it since it is from a log homes site.

Here's another link listing wildflowers of Minnesota. You may have many of these already on your lot! Many of them are protected, but here in Ontario many protected flowers are available at the larger nurseries. I'm assuming it is probably the same in Minnesota.

Diane, I have a question for you! Your house sits on a hill or rise, right? Do you have any plans to create a water feature? Perhaps, a small scale version of the waterfalls at Wilderness Lodge? If you do, and have a deck or patio with an eating area that overlooks it, that would be wonderful!! You could even name it....Artist Point!
Anyone else with some ideas/suggestions?
