Tree Indiana Native Quercus phellos [Willow Oak] Somewhat tolerant of city conditions. Oak wilt and scales, and many other oak tree pests, though none considered very serious. Low maintenance, long-lived tree. Use Northern sources in Indiana.

Hybridizes easily with other oaks (be careful of source).

Fall color not attractive (best to mow it down in the fall).
