Ilex aquifolium (Holly, or European Holly to distinguish it from related species, may also be called Christmass Holly or Mexican Holly) is a species of holly native to western and southern Europe, northwest Africa and southwest Asia.

It is an evergreen tree growing to 10-25 m tall and 40-80 cm (rarely 1 m or more) trunk diameter, with smooth grey bark. The leaves are 5-12 cm long and 2-6 cm broad, variable in shape; on young plants and low branches, with three to five sharp spines on each side, pointing alternately upward and downward; on higher branches of older trees with few or no spines except for the leaf tip, often entire.

The flowers are dioecious, white, four-lobed, and pollinated by bees. The fruit is a red drupe 6-10 mm diameter, containing four pits; although mature in late autumn, they are very bitter due to the ilicin content, and so are rarely touched by birds until late winter after frost has made them softer and more palatable.
