NICE Summer 2024 Plant of the Season

Texas Bluebells, Eustoma exaltatum ssp. russellianum, depending on where they grow, may grow as an annual, a biennial, or a perennial but in most of its range it is a perennial. Because it is one of the most beautiful wildflowers, it has been picked in such numbers that the wild populations have been unable to reseed in their native habitat. So, the plants are not commonly found except in cultivated locations. The very showy flowers are about 2 inches across and can be blue, purple, pink, yellow, or white. Bell shaped and upright, the flowers occur singly at the ends of long stalks from short branches near the top of the plant. Texas Bluebells plants are 1 – 1.5 feet tall and about 1 foot wide. The leaves and stems are blue-green and covered with a waxy bloom.

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.
