Quercus alba - White oak
Description: White Oak is a large, wildlife-friendly, deciduous tree of the white oak group. Mature White Oak trees are wide and spreading. It is monoecious; greenish-yellow flowers bloom on separate male and female catkins in April. It tolerates occasional flooding and drought, and has medium-high wind resistance. Acorns provide a valuable food source for birds and wildlife. White Oaks are host to numerous, inconspicuous insects, which in turn provide food for birds. It is a host plant for butterfly and moth larvae (caterpillars), including Edwards Hairstreak (Satyrium edwardsii). White Oak provides nesting space, cover, and shelter for wildlife. Use White Oak as a shade tree for your large yard, neighborhood park, or naturalized area. It can be used as a street tree, but needs room to spread.
