Colubrina texensis, commonly known as Texas colubrina, is a deciduous to semi-evergreen shrub or small tree native to limestone regions of Texas and northeastern Mexico, valued for its drought tolerance and finely textured branching structure. Mature plants typically reach 8 to 15 feet in height, though under favorable conditions they may grow as tall as 20 feet, with a spread of approximately 6 to 12 feet wide forming a rounded to irregular crown. The trunk is usually short and multi-stemmed, with individual stems measuring 2 to 6 inches in diameter, developing gray to brown bark that becomes slightly fissured with age. Leaves are small and glossy, generally ¾ to 2 inches long and ½ to 1 inch wide, oval to elliptic in shape with finely serrated margins, creating a delicate appearance along slender twigs that often measure only ⅛ to ¼ inch thick. In late spring through summer, clusters of inconspicuous greenish-white flowers appear in axillary cymes about ½ to 1 inch across, later producing small rounded seed capsules roughly ¼ inch in diameter that split open when mature. The root system is moderately deep and spreading, commonly extending 6 to 10 feet outward, allowing the plant to thrive in rocky, well-drained soils and withstand extended dry periods. When fully mature, Colubrina texensis occupies a landscape footprint roughly 8 to 14 feet across, functioning effectively as a native screening shrub, wildlife plant, or small ornamental tree suited to xeric and limestone-based landscapes.
