Red Oak
(Quercus rubra)
plant distribution
Height:
A ten year old tree can grow up to 5-6m.
Leaf and Bark Type:
Bark is brownish gray, becomming dark brown on old trees. The leaves are alternate, lobed, oblong-ovate to oblong. The leaves, when mature, are a dark green or yellowish green. In the autumn they turn red or a brownish color. Even though the leaves are bitter, they are eaten by deer, squirrels, and birds.
Where does it grow and in what conditions:
Although very popular in the Northeast United States, the tree is known for its cold hardiness. The acorns on the red oak will not germinate without a minimum of three months' exposure to temperatures below 40 degrees fahrenheit. They do well in West Texas and can tolerate drought.
Pollinators:
The flowers are wind and bird pollinated.
Nuts:
The nut is an acorn that takes about two years on the tree before development is complete. It is partially covered with a cap, that changes from green to greenish-brown to then brown.
Uses:
The red oak is an ornamental tree but also is valuavle for the wood it produces. It is one of the most important oaks for timber production in North America. It can be used for flooring, furniture, interior trim, etc. Because the wood grain is so open, it is subject to flooding, therefore not suitable for boats or exterior trim.
