Among those yellow wildflowers that are starting to bloom in the Hill Country is Engelmann daisy (Engelmannia pinnatifida). Engelmannโ€™s salvia (Salvia engelmannii) will bloom soon. Engelmannโ€™s prickly-pear (Opuntia engelmannii) is one of our common cactuses. Other Hill Country natives are Engelmannโ€™s milkweed (Asclepias engelmanniana), Engelmannโ€™s dock (Rumex hastatulus), and Engelmannโ€™s spike-rush (Eleocharis engelmannii).

The scientific and common names of many other native plants of Texas commemorate George Engelmann. โ€œEngelmannโ€ vies โ€œLindheimerโ€ for the most common person name used in Texas native-plant names. That is fitting. The unique collaboration of Engelmann and Ferdinand Lindheimer during the mid-1800s made Texas flora known โ€˜round the world.

George Engelmann, like Lindheimer, was born in Frankfort, Germany. He was the eldest of 13 children in a well-to-do family. He claimed to have become interested in botany around the age of 15. Though Engelmann was seven years younger than Lindheimer, they were members of the same botanical society of Frankfort youths.

Engelmann studied in universities at Heidelberg, Berlin, and finally Wurzburg, where he received an MD in 1831. The next year he immigrated to the US, probably to invest an uncle’s money. He showed his continued interest in botany by first going to Philadelphia to visit the noted English botanist and zoologist, Thomas Nuttall, who had been curator of the Harvard Botanical Garden for ten years.

Engelmann apparently was curious about the less-explored areas inland. He went to St. Louis and from there made a solitary journey on horseback through the wilderness of southwestern Missouri, Arkansas, and western Louisiana, searching for geological specimens and new plants. Reportedly, he contracted a dangerous fever in the swamps of Arkansas, but was nursed back to health by a black family.

He then joined relatives and other German intellectuals who were living and working on a 360-acre Engelmann farm at Belleville, Illinois, southeast of St. Louis. This is the same farm to which Lindheimer headed after he landed in New York in 1834. The renewal of the Engelmann-Lindheimer friendship during their stay on this farm was to have a profound influence on Texas botanical studies.

After a couple of years on the farm, Engelmann moved back to St. Louis and established a flourishing medical practice. He remained interested in botanical research. He was the first to recognize that certain American wild grapes were immune to the plant lice that were devastating grape crops in Europe. After a botanizing trip to Arkansas, Engelmann published a monograph on the strange parasitic plant called dodder or angel hair (Cuscuta sp.).

Engelmann helped found the St. Louis Academy of Sciences, and he encouraged the wealthy businessman Henry Shaw to establish Shawโ€™s Botanical Garden and School of Botany, which became the Missouri Botanical Garden. Engelmann studied flora in the Tennessee Appalachians, the Colorado Rockies, New Mexico, and the West Coast. Among other things, he became an authority on the cactus family.

For many years Engelmann sent money, books, and supplies to Lindheimer in Texas. Lindheimer sent extensive plant collections to Engelmann, who, in turn, sent many Texas specimens to Europe to be described. In 1845, Asa Gray and Engelmann published โ€œPlantae Lindheimerianae,โ€ which made Ferdinand Lindheimer famous in America and abroad.

It is largely thanks to Engelmannโ€™s collection of Lindheimer letters, preserved at the Missouri Botanical Garden, that we have insight into the passion and drive of the New Braunfels resident who would become known as the Father of Texas Botany.

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 fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
