Country of origin: Simone Giuliani Plant: Holy Oak
Holy Oak, the evergreen oak, holm oak or holly oak is a large evergreen oak native to the Mediterranean region. It takes its name from holm, an ancient name for holly. It is a member of the white oak section of the genus, with acorns that mature in a single summer. It was first introduced to the United Kingdom in the 16th century.
Quercus ilex is a medium-sized tree 20–27 metres (66–89 ft) tall with finely square-fissured blackish bark and leathery evergreen leaves. The old leaves fall 1–2 years after new leaves emerge. The leaves are dark green above and pale whitish-grey with dense short hairs below. The leaf shape is variable (depending on age and growing conditions), the adult leaves are entire, 4–8 centimetres (1.6–3.1 in) long and 1–3 cm (0.39–1.18 in) broad, while those on the lower branches of young trees are often larger (to 10 cm or 3.9 in long), and are toothed or somewhat spiny – possibly as protection from grazing animals. In this, the foliage resembles that of the common European Holly Ilex aquifolium, and this resemblance has led to its common and botanic names. The name ilex is originally the classical Latin name for the Holm Oak, but was later also used as a botanical genus name for the hollies. The flowersare catkins, produced in the spring; the fruit is an acorn, which matures in about six months.
