• Quercus rubra - Northern Red Oak


    "Northern Red Oak is a deciduous tree that may grow 60 to 90 feet tall and is found throughout the Piedmont and mountain areas of NC. It commonly grows on mesic slopes and well-drained uplands, on lower and middle slopes, in coves, ravines or valley floors. Most commonly on N- and E- facing slopes, and on clay, loam, and sandy or gravelly soils.

    "The leaves are alternate with 7 to 11 bristle-tipped lobes. The bark is smooth on young trees but as it ages wide, flat-topped ridges and shallow furrows develop. The shallow furrows form a pattern resembling ski tracts. In spring, yellow-green, cylindrical, male flowers and small, green, female spikes mature. The tree produces a 3/4- to 1-inch acorn with a flat, thick cap that covers about 1/4 the nut. The acorn requires two growing seasons to reach maturity. Northern red oak generally first bear fruits at 20-25 years but don’t produce acorns in abundance until 40-50 years. 

    "This plant is tolerant of urban conditions including dry and acidic soil and air pollution. It sustains the best growth in full sunlight with well-drained, slightly acidic, sandy loam. Use as a shade tree, street tree and in recreational areas." (North Carolina Extension)
