Mexican Buckeye

Ungnadia speciosa

FAMILY: Sapindaceae (Soapberry Family)

A resilient native native Texas tree that provides year-round foliage and structure to the landscape. Native across the Central Great Plains, Chihuahuan Deserts, Cross Timbers, East Central Texas Plains, Edwards Plateau, Gulf Coast Prairies and Marshes, Southern Texas Plains, and Texas Blackland Prairies, Mexican Buckeye (Ungnadia speciosa) thrives in local conditions while supporting the surrounding ecosystem. During spring, the plant produces delightfully fragrant, pink flower clusters. Flowering gives way to ornamental capsules that ripen through summer and autumn. It plays a vital ecological role as a larval host plant for Central Texas butterflies, including Henry's Elfin. Thriving in caliche, clay, dry, limestone, loam, rocky, sand, and well drained, Mexican Buckeye demonstrates outstanding hardiness once established. It requires minimal supplemental water and adapts seamlessly to drought conditions. It features high deer resistance.
