Durmast Oak

(Sessile Oak, Irish Oak)

Quercus Petraea

A large, long-lived, iconic shade tree native to Europe that is the national tree of Ireland. Very similar to the English Oak but often has a more upright trunk with straighter branches. Attractive glossy, green, lobed leaves and large acorns that provide valuable food for local wildlife. The acorns are edible to humans if the tannins are leached out. Trees have both male and female flowers on same tree and are wind pollinated but set seed better when more than one tree is present. Takes about 20 to 30 years to set seed and can produce hybrid seeds if planted near other oak species from white oak group.
