I am interested as well. I was going to ask how your roses made it through the winter but from the news it looks like winter is still there. Lol

I have my Prairie Peace in full sun. My understanding is Prairie Peace is a hybrid spinosissima, or scotch rose. I noticed a row of established scotch roses grown in a shady alley in town and they have done fine and flower moderately well.

This is a very late response, but I have some PP in full sun and some gets a little more shade. The plants in partial shade don't seem to flower as much but the plants themselves still got quite large. It is a very tough rose, so it'll survive fine I think, it just won't go all out blooming.

Thanks everyone for your input. I was hoping that the Spin genes would give Prairie Peace some shade tolerance.

I know for a fact, that John Davis is very shade tolerant. Mine is covered in flowers in June, with about 3-4 hrs of sun.....
