Several of them sound really distinctive with green accents. Green accents seem to be a very popular thing in peonies lately! I'd love to see them in real life. It's so hard to tell what's too similar to spend the energy/time/money to track down from just a few photos. There are field pics of Triphena Parkin on Facebook, looks really pretty.
You're right, Tracey. I'm perfectly content with my peonies when they're growing and in bloom, it's just harder when it's cold out and everything's brown and dead...
