In this revised edition of her popular Wildflowers of Texas, native-plant expert Geyata Ajilvsgi gives lay readers the most comprehensive field guide currently available on the state’s abundant wildflowers. With the addition of 105 species, the book now contains information on 462 of the most common wildflower species found in the state’s major vegetation zones — from the mountains in the west to the swamplands in the east, from desert to piney woods to coastal plain, from the Panhandle to the semitropical Rio Grande Valley. Each entry reflects the most current scientific knowledge about the plant, such as recent changes in taxonomic classification.

Designed for ease of use in the field, the guide is organized by color — the most obvious characteristic of flowers. The species are thus grouped into four sections: white-green, yellow-orange, red-pink, and blue-purple. Within each color section the species are arranged alphabetically by family, then genus and species. Information about each species includes its bloom period, range and habitat, botanical description, and other helpful facts. A special note in each entry explains the plant’s therapeutic, culinary, or other traditional uses as well as its landscaping value. Alternate common names and the origin and meaning of the plant’s scientific name are also provided, giving readers insight into the rich history and lore of botany.

To simplify the identification of wildflower species in the field, a full-color photograph of each flower appears on the page facing the entry. The book’s stunning photography is the work of not only the author but also some of the best-known nature photographers around the state.

A color map of Texas shows the state’s major vegetation zones, corresponding to the range codes used in the text. This enables the reader to determine at a glance the geographic range of a particular species. Other supplementary material include botanical and plant glossaries and bibliography.

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.
