Noteworthy Characteristics

Quercus stellata, commonly called post oak, is a medium-sized deciduous oak of the white oak group that typically grows 35-50’ tall with a rounded crown. It is called post oak because its durable wood has been used for fence posts. It is commonly found on lower mountain slopes and coastal plains in the southeastern and southcentral U.S. In Missouri, it typically occurs in dry soils on rocky upland slopes, woods and glades or in moist soils along streams (Steyermark). Insignificant yellowish-green flowers in separate male and female catkins appear in spring as the leaves emerge. Fruits are oval acorns (to 3/4” long), with bowl-shaped cups extending 1/3 to 1/2 the acorn length. Acorns are an important source of food for wildlife. Rough, often leathery, dark green leaves (4-8” long) with 3-5 rounded lobes have a cruciform appearance due to large wide-spreading central lobes. Fall color is variable, ranging from uninteresting to quality shades of yellow and brown.

Genus name comes from the classical Latin name for oak trees.

Specific epithet means starlike, in probably reference to the leaf shape, which is actually more cruciform than starlike.

post oak is generally considered to be a low-maintenance, long-lived tree.
