The Nut Trees were established in 1982 in the far southwest corner of the 40 acres. Three men, the late Archie Sparks, the late Al Ferguson, and Ward Mally, are closely associated with this collection. They planted some of their favorites and own introductions of black walnut (Juglans nigra), shagbark hickory (Carya ovata), chestnut (Castanea), and hazelnut (Corylus americana). The cultivars in this collection are selected for large edible nuts. Other selections of these species with smaller nuts may be more suitable as shade trees and are found elsewhere on the grounds.
