White acorn tree7/25/2023 As a result, most successful oak seedlings are usually found areas which receive full sunlight during part of the day. White oak is moderately intolerant to shade. Its common associates are other oaks, hickories, ironwood, black cherry, white ash, aspens on drier sites and maple, basswood, and bitternut hickory on more moist sites. It prefers soils which are moderately well drained or better and slightly acidic. It also occurs on moist sites, but usually is found in greater abundance towards the ridges and drier sites. In its range, white oak is one of the most abundant trees, often dominating the drier upland forested areas. White oak is native to most of Iowa except far western Iowa and the Northwestern corner of the state. The bark on mature trees is light ashy gray in color, separating into small scaly plates on old trees, bark may be furrowed with rectangular blocks. Buds are clustered at the tips, blunt to oval in shape and usually reddish brown to brown in color. Twigs are moderately stout, red often with a purplish tinge. Surface color is dull green and paler below. The lobes are rounded without bristle tips and vary in length from leaf to leaf but are rather uniform on the same leaf. They are 7 to 9 lobed, 5 to 9 inches long with short petioles. White oak leaves are simple and arranged alternately on twigs.
