CRITIQUE

English oak is a long-lived oak with a broadly rounded to spreading habit with a short trunk. It is an excellent specimen tree or can be planted in a grouping in large open landscapes. The acorns form a valuable food source for several small mammals and some birds but trees may take up to 20 years to produce fruit.
