Bur Oak - Quercus macrocarpa
One of the fastest growing oaks, growing as much as 30 inches per year as a rule. Illinois is the prairie state and Bur Oak is the prairie oak. Very tolerant of heavy clay soil, high pH, and open areas. Bur Oak is bimodal, growing in the uplands as well as the bottomlands. This indicates it is a very adaptable tree. Bur seems to prefer heavier soils to sandy ones, and it definitely needs full sun. Very asymmetrical in youth, it becomes more symmetrical as it matures.
