American Holly

Delaware designated American holly (Ilex opaca Aiton) as the official state tree in 1939. Also called Christmas holly or evergreen holly, American holly is regarded as one of Delaware's most important forest trees.

The tree has dark, thorny-leaved foliage and red berries. In Delaware, the tree can reach 60 feet in height and a trunk diameter of 20 inches.
