Holly is an evergreen tree belonging to the genus Ilex of the Aquifoliaceae family, reaching up to 13 meters in height. It originates from the subtropical regions and has a widespread distribution in China. The holly remains green all year round, is relatively cold-resistant, and does not shed its leaves in winter, hence its name. Holly bears small red or black berries, is highly resilient, and is commonly used for urban greening, courtyard gardens, and other decorative purposes. It grows in evergreen broad-leaved forests and at the forest edges on slopes at altitudes of 500 to 1000 meters.
