Quercus bicolor habitat P. Showers habitat

Floodplains, swamps, and other poorly drained sites. The undersides of the leaves in this species are usually more densely stellate-tomentose than in Q. prinoides, Q. montana, and Q. muehlenbergii, feeling rather velvety to the touch. The very whitish aspect of this surface on normal leaves is the basis for the epithet “bicolor;” however, shaded leaves or those on juvenile plants may be green and sparsely pubescent beneath. Especially on open-grown trees, the lower branches tend to hang downward and to persist when dead. An apparent hybrid with Q. prinoides, Quercus × wagneri Gaynor, has been described from Livingston and Washtenaw Cos.
