Northern Red Oak

(Red Oak)

Quercus Rubra

A large, long lived, stately shade tree native to New Brunswick. The most abundant oak found growing in parks, gardens and along streets across the province. Attractive shiny, dark-green, bristle-tipped, lobed leaves and acorns that provide valuable food for local wildlife. Trees have both male and female flowers on the same tree and are wind pollinated. Yields better seed crops when more than one tree is present through cross pollination. Can produce hybrid seeds if planted near other oak species from red oak group. Prune in late winter or early spring to avoid transmission of pathogens.
