Hill Country: Right seed, right location by David Touchon

I never thought that I would write an article about seeds but then I had a thought while walking the margins. We have a massive seed bank within the soil just waiting for the right moment. We know the home ranges so why not go local with the seed harvest? It’s free!

Late summer is turning quickly turning into Autum and the native plants have kicked fruit/seed production into high gear. It is important to note that I will only reference plants that are native to the Texas Hill Country.

The goal of every plant in the Texas Hill Country is to produce a seed, distribute it by any means possible and increase their range. The plant life cycle is six words: Seed, Root, Stem, Leaves, Flower and Fruit, repeat six times. Seasonal variations can occur, but we aim for the Spring rise, Summer Growth and Fall harvest. (see Dark Season and Light Season articles)

Many plants have developed highly specialized seed distribution methods, and the primary method comes in the form of being eaten! Many seeds require mechanical scarification or gastric acid interaction to germinate so the sweeter the fruit the better! Birds have firm control of this process, just ask the Ashe Juniper and Sugar Berry.

Other woodland fruit offerings might include Anaqua, Persimmon, Carolina Buckthorn, Gum Bumelia, Possum Haw, Escarpment Black Cherry, Mustang Grape, Virginia Creeper and Mexican Plum. A special mention will go out to Bois d’Arc (Horse Apple) since it was a favorite food item of Mastodons, Mammoths, Ground Sloths and many other Megafauna now extinct.

If you are not sweet enough to eat you will need to grab a ride. The “travelers” have developed highly specialized seed coats that allow them to stick, cling, poke and claw into an animal’s fur for distribution. Some of the Hill Country favorites might include Beggers Lice, Cockle Burr, Bed Straw, Spear Grass, Sand Spurs, Nut sedge and my favorite Devil’s Claw. Pro tip: Main and Tail detangler!

Nuts: Armored seeds that are typically very tasty and usually defeated by squirrels. These nut bearing trees are often referred to as “Mast” crops and work the statistical probability of re-seeding. These trees produce a massive number of nuts but only a few will avoid being fed upon, browsed or cleared. (see Brush Use Theory Article). The short list of these trees might include Pecan, Black Walnut, Mountain Laurel, Texas Buckeye, Mexican Buckeye and all Oaks. Special mention to the Bald Cypress and cone production.

The airborne seed category is wildly varied and capable of traveling great distances. Many airborne seed species are light by design which allows them to become aloft through silky parachutes, wooly masses, wings or wafer like discs. Some of the common airborne travelers might include Milkweed, Cottonwood, Cedar Elm, Big Tooth Maple, Baccharis and Sycamore. Airborne seeds can be considered Water borne in many cases.

Native grass seed readily roams but tends to “radiate” from a well-established center point. Grass seeds will show twice a year, late spring and fall, which is helpful within your management plan. The stars of the Texas Hill Country grass community are Switch grass, Canada Wildrye, Lindheimer Muhly, Indian Grass, Side Oats Grama, Little Blue Stem, Gamma Grass and battle tested Inland Sea Oats!

“Right seed, right location” is the time-honored mantra of all land managers so harvest some native seeds this Autumn, make note of the parent seed source, observe growth habits and plant! The fall projects are almost here and never missing a chance to create wildland connections! See you in the Prairie!

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.
