Quercus lyrata, also known as overcup oak, is a medium-sized deciduous tree native to lowland wetlands in the southeastern United States. The tree produces lyre-shaped leaves and acorns largely enclosed in a cup. Overcup oak is valuable for its wood, similar to that of other white oaks, and used for various purposes. The tree is a dominant species in the forest cover type Overcup Oak-Water Hickory and is often associated with water hickory, willow oak, Nuttall oak, and red maple, among others. Overcup oak thrives in warm and humid climates with adequate precipitation. Despite being notorious for various defects caused by insects like wood borers, overcup oak also suffers from heart rot caused by injuries, particularly those resulting from fire. Female and male flowers appear in April and May, and the tree bears acorns, which ripen between September and October. Overcup oak is a wonderful addition to any garden or landscape, thanks to its distinct features and unique habitat requirements.
