With this crazy weather this year if you have tree peonies start checking the buds. At the start of December two of my plants started opening buds. Luckily with in a day or so it got real cold. This past week and it looks like next week also we will be in the upper 40's and 50's. Just the right temps to break dormancy. If you see your tree peony buds opening you might want to provide additional shade or mulch. If the buds expand too much you can lose your flowers. This is especially a problem with chinese tree peonies from the central plains region, the type most frequently imported to this country.
