Bur Oak
Quercus macrocarpa
A majestic tree that grows best in deep limestone soils of riverbanks and valleys but it will adapt to many different environments. It has a long taproot which makes it hard to transplant but also very drought-tolerant. It is also fast growing and long-lived. Bur oak is noted for its very large leaves and acorns: the leaves are from one-half to one foot long, and acorns can be as large as 2 inches long and wide, enclosed in a cup with fringe on the edge. It casts deep shade.
