Monterrey Oak

Quercus polymorpha

FAMILY: Fagaceae (Beech Family)

A resilient evergreen native Texas tree that provides year-round foliage and structure to the landscape. Native across the Southern Texas Plains, Monterrey Oak (Quercus polymorpha) thrives in local conditions while supporting the surrounding ecosystem. Its dense, persistent foliage provides year-round thermal cover, privacy screening, and evergreen architectural structure. During spring, the plant produces green flower clusters. Flowering gives way to ornamental nuts that ripen through summer and autumn. It plays a vital ecological role as a larval host plant for Central Texas butterflies, including Skippers, Hairstreaks, and Admirals. The species provides essential habitat and food, supporting Birds, Deer, and Small Mammals. Thriving in clay, loam, poor drainage, rocky, and sand, Monterrey Oak demonstrates outstanding hardiness once established. It requires minimal supplemental water and adapts seamlessly to drought conditions.
