Burgundy/red shrub other than barberry?
I'm looking for something in the burgundy/red/purple range, hardy to 4A, other than barberries. Anything? At this point I am flexible as to size and texture. I would also consider a barberry if it were thornless, or if there were weeping varieties (if I just had to!).
I have seen some mounding acer palmatums on Sooner's website, one or two of which are listed as hardy to zone 4, but they are currently sold out, and since I'm mainly in the information-gathering phase, I would love some other ideas/knowledge/thoughts from you all.
