Ilex opaca - American Holly
The height of American holly or Christmas holly ranges from 25 ft. to as tall as 60 ft. in the warmer parts of its range. The stout, stiff branches of this pyramidal evergreen bear dark green, non-glossy, spine-tipped leaves. New growth finally pushes off the old leaves in spring. Bright red berries occur on the female plants. A shorter, multi-trunked form may grow in lower-light situations. The bark is a light gray color.The evergreen fruiting branches from wild and planted trees are popular Christmas decorations. Many improved varieties are grown for ornament, shade, and hedges. You must have both a male and female plant to have berries, or at least have the opposite sex growing wild somewhere nearby. The male must be the same holly species as the female and bloom at the same time. This is a very slow-growing tree. The whitish, fine-textured wood is especially suited for inlays in cabinetwork, handles, carvings, and rulers, and can be dyed various shades, even black. Many kinds of songbirds, gamebirds, and mammals eat the bitter berries of this and other hollies, but the fruits are poisonous to humans.
