Among the most beautiful plantings in the arboretum is the large azalea garden. A perennial garden is bordered by a formal hemlock maze. The arboretum is home to 20 rare American chestnut trees, the subject of research. A 22-acre nature preserve, open daily dawn to dusk, is home to many birds, including 20 types of warblers. The park has a 1,700-foot Famous and Historic Tree Trail.
Trees are descendants of ones at battlefields, historic homes, and one germinated in space.
