I planted tree peony ‘Joseph Rock’ in 2017. Purchased from Klehm’s Song Sparrow Nursery, which is unfortunately shutting down this year. My plant had three blooms this year, each as magnificent as the one in this photo. Although peony flowers are incredibly showy, there is something very refined and elegant about them as well. The blooms are short-lived however. I think each of the flowers on ‘Joseph Rock’ lasted about 3-4 days this year. My plant started blooming on May 20. Note: I took this photo in the late afternoon and so the colors are a bit dull.
