Quercus rubra leaf

Quercus rubra is grown in parks and large gardens as a specimen tree. It is not planted as often as the closely related pin oak as it develops a taproot and quickly becomes difficult to transplant, however modern growing pots have made starting seedlings with taproots easier than in the past Quercus ilicifolia × Quercus rubra → Quercus ×‌fernaldii Trel. is a rare oak hybrid known from MA, ME. It shows intermediacy in leaf blade outline and pubescence, terminal winter bud pubescence (they are sparsely pubescent), and fruit size (see identification key for details) The Northern Red Oak is botanically called Quercus rubra . The Tree is a deciduous tree, it will be up to more than 30 m (99 ft) high. The leaves are sinuate and the flowers are green-yellowish. The tree likes Sun to half-shade at the location and the soil should be sandy to loamy to strong loamy An adaptable, widely planted oak with a rapid growth rate, red oak will reach a height of 60 to 70 feet and a spread of 40 to 60 feet when open-grown, and is native to rich woodland areas where it will grow to 90 feet tall. Branches and upper trunk are marked with long, light grey longitudinal lines which remind some people of ski trails

Quercus is the Latin name for Oak. rubra translates as red, referring to the red fall color, red petioles, or reddish interior wood. The common name of Northern Red Oak implies that there is, in fact, a Southern Red Oak (Quercus falcata), which is the predominate member of the Red Oak group in the mid-South Quercus rubra: Northern Red Oak3 Aphids cause distorted growth and deposits of honeydew on lower leaves.
