Description:

Scrub Oak, or Bear Oak, is a small, shrub-like, deciduous tree in the red oak group. It is monoecious; separate male and female catkins appear on the same tree. Its smooth leaves have 3-7 bristle-tipped lobes. Fall foliage is reddish-purple. Biennial acorns are bitter and reportedly only eaten by bears. It provides nesting space, cover, and shelter for wildlife. Oaks are host to numerous insects, which in turn provide food for birds. Scrub Oak is a host plant for butterfly and moth larvae (caterpillars), including Sleepy Duskywing (Erynnis brizo) and Eastern Buckmoth (Hemileuca maia). Use it as a street tree or shade tree in your yard, neighborhood park, or natural area.
