An Illustrated Guide to the Native Plant Garden by Susan Carpenter
Bur Oak (Quercus macrocarpa) is relatively fast growing tree of open sites, on a wide range of soils. The buds and leaves have rounded tips and the large acorns have a conspicuous fringed cap. Acorns germinate the season they are produced (but often the squirrels find them first). This species is drought, ozone and salt resistant. Its spreading horizontal branches and substantial twigs give the tree a beautiful shape—summer or winter.
