Overview. Burr oak, also spelled bur oak, is a tree with many striking features, including crooked branches, large leaves and big acorns.
Aristocrat ornamental pear trees have smooth branches that grow outward, rather than upright. This results in a tall, oval-shaped tree that averages 24 to 40 feet in height and is less susceptible to wind damage than more spreading trees. The trees grow in USDA hardiness zones 5 to 9 in full sun.
