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. The distinctive wavy, edged, lobed leaves can reach up to 15cm long, they are produced on long stalks and display attractive autumn colouration, changing from dark green to orange and brown. 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.
