Originating from Europe, the Sessile Oak is a great wildlife tree, providing habitat to a range of species. It is a large, hardy, deciduous tree species from the Fagaceae family.

It forms a broad, rounded crown with age, flowers are not showy, coloured green-yellow and arranged on hanging catkin structures. The blooms are wind-pollinated, female flowers develop into green acorns, which ripen to brown. Grow in full sun to partial shade, in moist, well-draining soil.
