Maintenance

A hardy, drought tolerant shade tree. Relatively fast growth rate. Adapts to a variety of soils. Prune only as needed to raise canopy for walkways. This species flowers in fall, so refrain from major trims in late summer. Fall foliage will turn yellow except in the southern part of its range. No need to rake the small leaves, they provide compost for the tree. Susceptible to Dutch elm disease. Propagation: seed.

Comments

A large tree with an oval-rounded crown and scaly bark. Young trees have corky wings on their branches. Dark-green leaves are small and rough textured. Inconspicuous flowers appear in clusters of three to five, and hang in the axils of the leaves. The fruit is a round, flat, winged samara. Larval host: Mourning Cloak, Question Mark. Replaces non-natives: Chinese Tallow Tree, Chinaberry.

Seed Stratification Fall-ripened seeds may be stratified for 30-60 days at 36-40 degrees. Collect seeds by raking from the ground soon after they fall or by stripping them from the branches. Air-dry a few days before storing. https://www.wildflower.org/plants/result.php?id_plant=ULCR

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our four host chapters (New Braunfels, Lindheimer, Guadalupe, and the Hill Country chapters) are located in one or both of the ecoregions above. However, the eastern portion of Guadalupe County also falls within the Post Oak Savanna ecoregion. Annual rainfall averages 35 to 45 inches, with higher averages to the east. A wide variety of hardwood trees are found, including several species of oaks, elms, and in the Bastrop area, loblolly pine (Pinus taeda). Grasses and forbs dominate in the open savannas, with most common grass being little bluestem. Ranching, agriculture, and fire suppression have allowed woody species to encroach on the once-open savannas.
