Oak trees come from acorns. Acorns are nuts produced by oak trees that drop to the ground in early autumn. Although not generally eaten by modern humans, acorns are beloved fare of squirrels and chipmunks.
Oak tree types can be identified by their leaves, their acorns and bark, their habits, and the places where they grow. The sessile oak has leaves that are dark green on the top but pale and hairy beneath and that usually have five lobes.
To identify oak trees using leaves, examine the leaf branching on the corresponding tree, determine if the leaf is simple or compound, and look for lobes on the leaf's edge. Also, check to see whether the lobes are pointed or rounded, observe the sinus depth, and look for leaves that are shaped oddl
One of the largest, fastest growing and most resilient oak trees, the red oak tree thrives even in imperfect soil and polluted air. It reaches a height of 60 to 80 feet, and its branches span 40 to 60 feet across.
Oak trees can be found in almost every state in the United States. Oaks tend to grow very well in the hot, humid climates in the south, but some oaks, including the Northern red bur and the white oak, have a growing range that extends to the coldest climates in the north.
The growth rate of oak trees varies depending on the species. Oak trees may be classified as deciduous or evergreen trees and grow at very slow or quite rapid paces. Some oak trees take nearly a century to reach their full heights, while others mature in half that time.
Several commonly planted trees have white bark, including varieties of birch, sycamore and poplar. Among these trees, however, the look of the bark and trunk and their particular shade of white can differ greatly. Thus, an inspection of both, as well as the trees' leaves, can help with identificatio
When identifying different oak tree leaves, five factors come into consideration. Look at the tips of the lobes, number of lobes on the leaves, color changes in fall, overall size of the leaves and the geographical location.
Oak trees are known for reaching massive heights, have spirally-arranged, broad leaves and produce fruit in the form of acorns. Most oaks are deciduous trees that are free of pests and diseases.
While there are over 400 types of oaks, some of the varieties in the United States include black oak, white oak, northern read oak and live oak. The fruit of oak trees is the acorn, and the leaves form in an alternating pattern.
