Description:

Glandularia bipinnatifida, known as Prairie Verbena in Texas, has a number of other common names including Dakota Mock Vervain and the poetic Spanish Moradilla, meaning “Little Purple One.” It is found widely in Texas and ranges to Central America. It prefers grassy, prairie habitats in nature. Prairie Verbena is in the large verbena family, which also contains Texas native favorites Frogfruit (Phyla nodiflora) and Texas Lantana (Lantana urticoides). Prairie Verbena is a short-lived, short-statured deciduous perennial growing to one foot tall and one and a half feet wide with widely dissected medium green leaves.

Flowers and Seeds:

Prairie Verbena has a long flowering season, from March through October, with the heaviest blooms in the spring. Its flowers, usually in purple hues, are borne in clusters with each flower having five petals. Plus, it readily re-seeds.

Planting sites:

Prairie Verbena thrives in partial shade to full sun in a range of soil pH and soil types. It prefers dry to somewhat moist sites and, very importantly, must be well-drained.

Watering Instructions:

Water Prairie Verbena well when planting it or its seed. It is drought tolerant except in severe dry spells.

Additional Comments:

Prairie Verbena is a favorite plant seen along Texas roadways and in fields during its blooming season. It is well suited for home gardens, especially those not regularly irrigated. The “Little Purple One” attracts butterflies and bees, with its flowers providing a nectar source. In addition, it is deer resistant. Prairie Verbena is easy to grow and can be propagated by cuttings or by seed. Consider planting Prairie Verbena instead of non-native Perwinkle, Petunia, or Begonia. Companion species include Zexmenia (Wedelia texana), Mealy Blue Sage (Salvia farinacea), milkweeds like Antelope Horn (Asclepias asperula), Gayfeather (Liatris mucronata) and Sundrops (Calylophus berlandieri).

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.
