Quercus rubra – Northern Red Oak


Botanical Name: Quercus rubra

The Northern Red Oak (Quercus rubra) is a popular and adaptable medium to large sized deciduous tree. It is native to the eastern and central United States, as well as southeastern and south-central Canada. The growth habit is rounded but somewhat irregular, with an open, spreading crown. It grows to a height of 50-75 feet tall with a spread of 50-75 feet.

The Northern Red Oak tree is a member of the group of red oaks. Characteristic sharp bristles grow on the leaf lobes of these oaks. They also have acorns that develop after two growing seasons and mature in the spring.

The flowers are catkins – both male and female flowers grow on the same tree. They are yellowish-green, inconspicuous, and bloom in late spring. The fruits are acorns that grow up to ¾ -1 inch in size and sit on a flat cup. The Northern Red Oak may not produce a big crop of acorns until it reaches 40 years old.

The leaves are a glossy, deep green with light undersides and can grow up to 8 inches long. They have 7-11 lobes that taper to a sharp point at the end. In the fall, the leaves turn a brownish-red color.

The Northern Red Oak likes to grow in fairly dry conditions. It can withstand city conditions and works well as a street tree when there are no overhead height restrictions, such as power lines.

It can develop chlorotic leaves when it is planted in soils that are too alkaline. It can be susceptible to oak wilt but in general is a tough and long-living tree.
