Rockii-Hybrids have the beautiful color pattern in the center of the flower due to crossbreeding with the wild form P. rockii. Compared to the suffruticosa varieties, the Rockii-Hybrids grow much faster and more vigorously. Rockii-Hybrids also have a strong tendency to form basal shoots. This can result in quite wide bushes over the years, up to 1.8 meters in height. Rockii-Hybrids usually flower around the end of April, depending on the weather. They usually flower after the suffruticosa but before most of the Lutea-Hybrids.
In addition to Rockii-Hybrids, our Woody Peony assortment includes Lutea-Hybrids, European suffruticosa, Japanese suffruticosa and Wild Species. On this page you will only see Rockii-Hybrids now. For more information about woody peonies in general and useful tips for culture and care, click here.
