Quercus robur
English oak

Culture: Usage of this species is somewhat limited in the northern portions of the Midwest by the lack of cold hardy selections in the trade. This species performs best in acidic or neutral soils that are moist and well drained. It is moderately easy to transplant balled and burlapped.

The leaves of this species are usually gray in color in the late summer due to the presence of the powdery mildew fungus in humid climates. The mildew is unsightly but appears to have only a minor effect on the plant health. Other problems on this species are uncommon.

Usage: Because of its large size, this species is best suited to large landscapes, parks and golf courses. Given my choice, I would use the native species in preference to this European species, however large and beautiful specimens are possible. A variety of cultivars are available, including fastigiate, weeping, improved standard forms and hybrids with other oaks. 'Clemons' (trademarked Heritage) is a standard form from Earl Cully with good mildew resistance, a central leader and uniform crown.
