When I was back up in Michigan last May I noticed that there were lots of people who had planted clumps of the same dwarfs at the front of their houses, especially in the area between the sidewalk and the street. It looked really nice.
I have had no luck with getting dwarfs to rebloom down here in NC, so I can't say which would be best. I am sure Tom can tell you which of his rebloom in WI.
