What looks like a thistle but isn’t?

**ARCHIVED POST **

Basket flower can be mistaken for a thistle when you first see it. The flower has a similar profile and color. But luckily it lacks the prickly characteristics.

Basket flower or Centaurea americana is pretty enough to make the cover of the popular field guide Wildflowers of Texas by Geyata Ajilvsgi.

Its rich green leaves are simple and alternate, somewhat pointed. Summer blooms can be three inches or more in diameter. A creamy center is dramatically accented by lavender to purple outer edges. The numerous disk flowers are showy and so are the bracts that form what looks like a woven basket enclosing the buds and holding the flower head, hence the common name.

American basket flower is an imposing plant even when solitary. Its leafy stem often branches near the top bearing a number of blooms and buds. The whole plant can measure three to five feet tall. However when basket flower is massed as I often see it in areas collecting some run-off water, it is spectacular and makes one catch their breath.

In the wild I mostly see it in openings at the edge of the woods.

Basket flower came into my garden as seeds in the soil when I transplanted some salvias from an abandoned site. It’s an annual and seeds are available in many nurseries and green plants sometimes in nurseries. It’s a fragrant butterfly attractor. Although the literature says it likes full sun and dry soil, my experience is that it does better with a little shade.

Each of the pink corollas is attached to a developing seed.   When the seeds can be easily removed from the disc of the mature seed head by pulling gently on the fluff attached to the seed, they are ready to be harvested.

Here is an interesting little fact — if you touch the stamens they retract. According to Zoe Kirkpatrick in Wildflowers of the Western Plains, “when roving, probing insects make contact with them, they contract instantly, pushing pollen out over the insect to be carried to the next blossom.”

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.
