  • The word quercus is the classical Latin name of oaks, said to be derived from Celtic fine and tree.
  • Oaks can reach a height of 125 ft (38 m), with large diameters.
  • The sapwood of oak is white to very light brown, while the heartwood is light to dark brown in the white oak group and reddish brown in the red oak group. Oak wood has a course texture; it is heavy, straight-grained, hard, tough, very stiff, and strong. Fast-grown oak, with wide rings, is stronger and heavier than slow-grown oak.
