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

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
