Paeonia rockii, 'Phoenix Hairpin' Chinese rockii tree peony
Name in Chinese and pin yin: 釵頭風 Chai Tou Feng
Notable characteristics: Distinctive purple-magenta blossoms in a unique anemone double form. Extremely fragrant. Foliage is finely cut, making an elegant display even after the bloom. Rockii tree peonies are native to Gansu Province, in northwestern China and are extremely tolerant to a wide temperature range. Summers in Gansu can reach 100 degrees easily, and winters are below zero. In Connecticut, we have found rockii hybrids to be some of our favorite tree peonies.
