Quercus ilex Holm oak, Holly oak, Evergreen oak

A selection with a steeper and more uniform manner of growth. Fairly fast-growing, with low branches that stand at an angle of 45°. The short trunk is greyish-brown and has fine grooves. Parts of the bark flake off in platelets. Young twigs are thick, hairy and olive-green. Older twigs are bare and grey. The obovate leaves are deeply and regularly lobed. The large lobes are also lobed or carry blunt serrations. The leaves are glossy dark green, the underside lighter. They are 10 - 20 cm long, sometimes longer when the tree grows vigorously. Width 7 - 12 cm. The acorns are one third to a half enclosed by the cupule: the latter is densely covered with narrow, contiguous, hairy scales. The cupules and the leaves are very characteristic of the species.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2024.

Quercus ilex is average growing and can eventually reach a height of 20 - 25 m, depending on the site and climate conditions.

The right time to plant Quercus ilex is during the dormancy period. In Western Europe, Quercus ilex with root balls can generally be planted from mid-November to late April, although this depends strongly on the climatic conditions and the species of tree.
