Also known has holly oak, this evergreen tree is native of the Mediterranean region and belongs to the beech family, Fagaceae, that also includes chestnut. The tree grows up 40-70′ tall and wide from a taprot and has many low hanging branches and a dense rounded crown. The bark is gray to black and the leaves are lanceolate to ovate, up to 3″ long, and dark glossy green with downy gray undersides. When young the leaves have toothed margins like those of holly, but as the leaves age the margins become entire. Small greenish yellow male and female flowers appear in spring on the same plant. The female flowers are in small clusters while the male flowers are in pendulous catkins. The fruit is a 1.5″ wide acorn enclosed in a cap that has downy scales and covers 1.3-1/2 the acorn. The fruit ripens in the fall. Holm oak is a good choice for a shade tree and street tree, and can be pruned into a hedge. It is tolerant of saline soil and wind so can be used in a coastal garden. The genus name, Quercus, is the classical Latin name for oak. The specific epithet, ilex, is the classical name for holly, and refers to the resemblance of the oak’s leaves to holly leaves.
