Maintenance

Grows in a variety of soils. Low maintenance. It spreads easily by rhizomes, so give lots of space or pull sprouts to fit the space. Best grown in moist prairies, meadows, and butterfly gardens. Can be grown in containers. Great for attracting late season pollinators. Propagation: seed, division, cutting.

Comments

Blooms July-October. Produces multiple branches covered in sprays of tiny, star-like flowers. The stems bear narrow, lance-shaped leaves, with toothed margins. They decrease in size as they go up the stem. Each blossom produces 20-40 white ray flowers surrounding pale yellow disc flowers. The disc flowers turn from yellow to reddish with age. The flowers are followed by a dry seed called a cypsela, attached to filaments that carry it on the wind.
Previous Scientific Name(s): Aster lanceolatus

Clump Division Carefully separate the root clumps and replant them. Large divisions can be planted into their permanent positions whereas smaller clumps should be kept in a cold frame until they are growing well. Take divisions in early spring or fall 1) https://earthone.io/plant/symphyotrichum%20lanceolatum 2) https://plants.usda.gov/DocumentLibrary/plantguide/pdf/pg_sylal4.pdf
Seed Stratification Pre-chill spring sown seeds to improve germination. Fertile flowers mature to a dry cypsela, 0.5 to 1.6 mm long, with a whitish pappus attached for wind dispersion. These seed heads are rounded and look like small dandelion seed heads. 1) https://plants.usda.gov/DocumentLibrary/plantguide/pdf/pg_sylal4.pdf 2) https://friendsofeloisebutler.org/pages/plants/whitepanicleaster.html

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.
