The Post Oak, or Iron Oak, (Quercus stellata) is a species of oak in the white oak group, known for its durability and resistance to rot, fire, and drought. It is commonly found in dry, sandy, and nutrient-deficient soils, often at the edge of forests, on ridges, or fields. Distribution: Q. stellata is widespread in the eastern and Midwestern United States, both inland and along the coast. It ranges from Massachusetts to Florida along the eastern coast, extends westward to Texas, and reaches as far north as Iowa. Identification Features: The tree typically grows 33-49 feet tall, with some specimens reaching up to 98 feet. It is easily recognized by its unique cross-shaped leaves with three perpendicular lobes, resembling a Maltese cross, and a densely hairy underside. The tree has a rugged appearance due to its distinctive branching pattern. Its acorns are 5/8 to 3/4 inches long and mature in their first summer.
