Member News: Promoting Native Milkweeds

By Greg Pearson, Clear Lake Chapter

Swamp Milkweed (Asclepias incarnata), from NPSOT Native Plant Database.

My interest in Monarchs and milkweed started following a trip my wife and I took to visit the Monarch wintering grounds in Mexico. After the trip, my wife and I added milkweed to our garden, but unfortunately, the only variety available at the time was Tropical Milkweed, Asclepias curassavica. After learning about all of the negative issues associated with tropical milkweed, we decided to replace it with native milkweed. Easier said than done.

After checking around, we found it was nearly impossible to find native milkweeds like our native Butterflyweed, Asclepias tuberosa. So, I embarked on a journey to grow our own. My first few naïve attempts were total failures. So, I took a step back, learned the basics of growing milkweed, and then worked on the method that I currently use. I started growing enough for our garden, but considering the need for it, I have since scaled up.

This year, I grew 500+ plants that I donated to our chapter plant sales, outreach giveaways, and other events. I also began leading workshops on growing milkweed through the Clear Lake Chapter and at nurseries as a means to further increase the supply. There is such a need for education about the importance of native milkweed, among both gardeners and professionals who work in the trade.

At one outreach function I met a nursery professional who was looking for a supply of native milkweed. They had been unable to source it from their suppliers and can’t been able to grow it on their own. After several conversations, we agreed that I could give a short workshop on growing native milkweed to their customers. I also volunteered to train their staff and help guide them through their first growing season (taking a NICE partnership up a notch)!

I encourage you to try any or all of these approaches to help increase the supply of native milkweed and help reduce or eliminate the use of tropical milkweed in Texas landscapes. I’m sure there are other local nurseries out there who would like to grow native milkweed. We should share our expertise.

If you’re interested in learning more about how to grow native milkweed–whether it’s for your own purposes, to share with your fellow chapter members, or to help educate your local nursery–please feel free to reach out to me. I’ll be happy to help you on this very important mission.

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.
