This entry has yet to be reviewed and approved by L2G editors.
A rounded canopy, oval acorns and deeply lobed, frilly leaves set 'Dissecta' apart from other English oak selections. A deciduous tree native to Europe and western Asia, it has bark that is ridged and furrowed, rich brown to gray-black in color. The leaves are oval but look shredded or eaten by caterpillars, as only long and narrow lobes exist. As the leave emerge, the pendent male flower spikes, called catkins, line the ends of branches. Soon after the pollen shedding ends, the small female blossoms open at the bases of new leaves on young twigs. Once pollinated, the female flowers develop into oblong oval fruits called acorns, singly or in clusters up to five. The leaves in autumn are held quite late on the branches, and rarely create any display of impressive color. Large birds, such as ducks, crows and quail, will use the acorns as food, as well as many rodents and small mammals.
Plant fernleaf English oak in a fertile, moist, well-drained soil for most robust growth. It prospers in sunny locations. Amazingly, this species is very tolerant of both dry and very alkaline soils, too. It is best suited for large lawns or meadows. In severe winters there is often significant twig dieback and mildew frequently affects the foliage during the growing season in regions with warm, humid summers.
