Granjeno provides food in dry conditions

**ARCHIVED POST **

Most native plant specialists encourage adventurous newbies not to compare the taste of native fruits to the exotic ones at the grocery store, but to appreciate the native fruits for their own unique tastes. An exception to this is Celtis ehrenbergiana, known as “granjeno”, “spiny hackberry” or “desert hackberry” throughout its native range.

San Antonio area horticulturist and native plant author Patty Leslie-Pasztor compares the taste of Granjeno to cantaloupe during her ethnobotany walks. Indeed, one of the qualities that endears it to those who harvest its fruit is that it is so much easier to get cantaloupe taste by popping a few small Granjeno fruits as if they were mints, than to prepare a melon.

The mature height of Granjeno is taller than humans, although in thickets Granjeno may reach in any direction to get adequate sunlight. Its intermingling with native shrubs and small trees adds so much protection for small native wildlife.

Celtis ehrenbergiana forms an understory with Agarita, Coma, Brasil; under elm, juniper, mesquite, Texas persimmon, between Salado Creek and Pecan Valley Lake in Southside Lions Park. This tree responded to dieback in the maintained right-of-way by spreading high into the surrounding thicket; creating strong protection.for wildlife.

The spines do not deter birds and humans from harvesting fruits as much as they can deter mammals from climbing the trunk. Jackrabbit and coyote are some of the animals that quickly devour any fruit that falls to the ground. The fruit is particularly attractive to birds in semi-arid regions, including cactus wrens and green jays. The spines make the plant an important component of thickets and understory where native birds seek shelter. Celtis ehrenbergiana is the larval host of Libytheana carinenta “American Snout” butterflies.

Native range of Celtis ehrenbergiana includes many Mexican states, from Chihuahua to Oaxaca; and California, Arizona, New Mexico, Texas; and Florida (where it is listed as “endangered”).

This small tree is a member of the elm family and hackberry genus. The smooth gray bark which appeals to humans is matched with spiny branches which sometimes discourage the casual observer from getting near. The ability of Granjeno to thrive in dry conditions makes it valuable for controlling erosion.

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.
