SIU 150th logo

This tree is one of the 150 trees initially included in the arboretum to coincide with the campus's 150th anniversary celebration.

Scientific Name:
Quercus stellata


Native to:
Eastern and central United States, and found in all the coastal states from Massachusetts to Texas, and as far inland as Nebraska

Mature Height and Width:
35-50 feet by 35-50 feet

Additional Notes:
Post oak exhibits exceptionally great resiliency under soil and climate conditions too dry for other oak species.  Some of the longest-lived trees across the harsher portions of the landscape, ranging from the woodlands of Texas through the Appalachian ridges to the coastal barrens of New Jersey, are post oaks.  Post oaks typically grow slowly and often have a rough and stunted appearance that seems fitting, given their innate toughness.
