The American holly (Ilex opaca) grows to a height of 40–50' and a spread of 18–40' at maturity. This tree is considered both an evergreen tree and an ornamental tree. It keeps its foliage year-round. The leaves stay green year-round. The American holly tree has been popular since the beginning of American history, having served the Native Americans with wood for many different applications and berries that were used for buttons and barter. It was said to be a favorite of George Washington, and more than a dozen hollies he planted are still evident today. It is also widely known as the basic raw material for Christmas wreaths. The first scientific observation of the American holly tree was recorded in 1744. The foliage of the American holly provides cover for songbirds and mammals, and after frost settles in, the fruit becomes a choice food for grouse, quail, wild turkeys and other songbirds. The flowers are also attractive to bees.
