Since peonies are one of those plants that can tolerate a tiny bit of cold weather you can plant them slightly earlier in the year than other plants that might not handle the cold.

The last month that you can plant peonies and expect a good harvest is probably September. You probably don't want to wait any later than that or else your peonies may not have a chance to grow to maturity. Starting your peonies indoors is a great way to get them started a couple of weeks earlier.
