Quercus imbricaria
Shingle Oak is a medium-sized, deciduous tree of the red oak group. It grows in conical form with a rounded canopy. It accepts pruning well and can also be used as a shrub. It is monoecious; greenish-yellow flowers bloom on separate male and female catkins in April as leaves emerge. The acorns ripen every second year, and provide food for birds and wildlife. Fall foliage is variable, sometimes yellow-brown to red-brown. Browned leaves persist on branches into winter and can help serve as a windbreak and provide winter shelter for beneficial insects. Oaks are host to numerous insects throughout the year, which in turn provide food for birds. Shingle Oak also provides nesting space, cover, and shelter for wildlife. Use it as a street tree or shade tree for your yard, neighborhood park, or in natural areas. It may be pruned to use as a hedge or privacy screen.
