Northen Red Oak 

The northern red oak is a medium-sized, rounded tree. When the tree’s leaves first begin to grow in the spring, they are of a bright pink-red color and may make the tree look as if it’s in bloom. These leaves have 7-11 lobes which are sharply pointed at the ends and turn bright red in the fall. The acorns on this tree are barrel-shaped with thin caps, and are among the first of the oak acorns to ripen, providing an early harvest for birds and mammals.
