How to tell it

A small, hard leaf, often spiny along the margin, dark green above and grey-white beneath. Dark bark cracked into small squares. A rounded, dense crown.

What it is confused with

Cork oak

Quercus suber

Harmless confusion

The bark settles it in two seconds: cork oak's is spongy and gives under pressure, holm oak's is hard and cracked.

What it is for

The holm oak acorn is sweet and edible, roasted or raw, a tradition that survived in Portugal into the 20th century in years of hunger. Today it is mostly the base of Alentejo free-range pork.

Traditionally used as food. This is not permission to eat it.

The law says

Legally protected in Portugal, like cork oak. Felling and cutting require authorisation.
