The native plant attraction – late fall bloomers bring out the butterflies

This week our yard is busy with all sorts of butterflies, from large monarchs and giant swallowtails to tiny skippers and hairstreaks. This may be the most butterflies weโ€™ve had all year.

Perhaps so many of those fluttering beauties are nectaring in our garden because the cupboards are bare in the neighboring yards without native plants.

In our yard, many of the drought survivors among our native and near-native plants have burst into bloom after the recent rains. This brought on the butterflies and bees!

The strongest butterfly magnets in our backyard are the fragrant clusters of white flowers on the thoroughwort or โ€œwhite mistflowerโ€ (Ageratina havanensis). This shrub is endemic to the eastern and southern Edwards Plateau and adjacent areas, and it is common in Kendall County.

Blue mistflowers (Conoclinium coelestinum) and a similar blue-flowered cultivar also are attracting a lot of butterflies. Apparently, any mistflower would be a star attraction in a butterfly garden.

Today I counted a dozen different kinds of butterflies and two kinds of moths crowding onto our thoroughworts.

One of our most drought-tolerant plants, flame acanthus (Anisacanthus wrightii), is blooming again, and the pipevine swallowtails seem to appreciate that.

The yellow-flowering goldeneye (Viguiera dentata) is another drought-resistant native that draws butterflies to our yard in the late fall.

Some butterflies are attracted to the pink flowers of palafoxia (Palafoxia callosa), which comes up naturally in our backyard and currently is in full bloom. A miniature purple verbena (cultivar) is getting its share of butterflies, too.

Most of the late-fall color at our house is thanks to all those savlias that survived our hot, dry summer. Salvia greggii made a great recovery from the drought and now is blooming bright-red, pink, and white.

Mealy sage (Salvia farinacea), shrubby blue sage (Salvia ballotaeflora) and giant blue sage (Salvia azurea) are three Hill Country natives that are blooming profusely this week, adding different shades of blue to our garden.

Mountain sage (Salvia regla), native to the Big Bend, is blooming red.

As is usual for this time of year, several of our Mexican salvias are flowering. Mexican sage (Salvia mexicana) has large dark-blue flowers and forsythia sage (Salvia madrensis) produces long spires of yellow blooms.

The long-blooming Salvia darcyi is putting on red flowers yet again. Mexican bush sage (Salvia leuchantha), one of the most easily grown salvias in the Boerne area, is producing showy spires of blue blooms.

Two other blue salvias are flowering again after suffering from the drought. Indigo spires (accidental hybrid) and Salvia guaranitica (South American) are making a late-fall comeback in our yard. They are survivors, even in the driest of years.

With certain native and native-compatible plants, even late-fall gardens can be colorful and full of butterflies.

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.
