Facts

Fuzzy pride-of-Rochester is a shrub related to Hydrangea that takes its common name from its fuzzy, scrabrous leaves and twigs. The bark, which peels in large sheets, is unmistakeable. Sprays of white, showy flowers (some varieities produce double corollas) mature into dry, brown capsules that can persist through winter.
