Mexican Buckeye
Ungnadia speciosa
Mexican Buckeye (Ungnadia speciosa) is a small, deciduous Texas native tree or large shrub appreciated for its light pink, fragrant blooms in early spring and its adaptability to a wide range of soil and weather conditions. It is commonly used in wildlife gardens, understory plantings, or as a small ornamental tree in drought-prone areas of Central and West Texas.
This species thrives in full sun to partial shade and grows best in well-drained soil, showing a strong tolerance for alkaline soils and poor rocky conditions. It is highly drought-tolerant once established and deer-resistant, making it a reliable performer in dry landscapes. The seeds are contained in hard, glossy brown pods that rattle when shaken—an appealing feature in naturalistic gardens.
Mexican Buckeye typically reaches 10 to 15 feet in height and width, forming a rounded, multi-trunked shape. When planting in groups, allow 8 to 12 feet of spacing. In addition to its attractive flowers and pods, it develops yellow fall color, offering seasonal interest beyond its spring bloom.
While sometimes confused with Red Buckeye (Aesculus pavia), Mexican Buckeye is not botanically related. Red Buckeye has red flowers, larger leaves, and prefers slightly more moisture, whereas Mexican Buckeye has pink flowers, smoother leaf texture, and greater drought tolerance. Additionally, their seed pods are shaped differently, and Mexican Buckeye's bark is lighter and smoother.
In USDA Zones 7–9, Mexican Buckeye is cold-hardy and typically requires no special winter protection. It responds well to light pruning in winter to maintain its shape or open up its structure.
