‘Patterson’ (C. mollissima) is an M. Nave selection from seed collected at the Nanjing Botanical Garden (provided by Nanjing Botanical Garden scientist Liu Liu). The selection has morphologies that differ from those of other C. mollissima trees cultivated in the United States, like its wide leaves. ‘Patterson’ also has a spreading, orchard-type architecture; however, it grows quite vigorously. The cultivar is highly productive despite setting fertile catkins, and its nuts vary in size (from medium to large) and become very sweet when cured (Miller, 2017; Nave, 2017). Greater evaluations in the East and Midwest are needed. ‘Patterson’ ramets were introduced to the UMCA repository in 2020.
