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

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.
