Coker Arboretum (5.3 acres) is an arboretum within the North Carolina Botanical Garden on the campus of the University of North Carolina, Chapel Hill, North Carolina. It is open daily without charge. The arboretum was established in 1903 by Dr. William Chambers Coker, the university's first professor of botany, who loved East Asian species and added many throughout the 1920s into the 1940s, including conifers and one Metasequoia, as well as daffodils and daylilies.
