Forecast: flowers followed by clouds of Clematis

**ARCHIVED POST **

Clematis drummondii, commonly known as Old Man’s Beard or Texas Virgin’s Bower, is known not so much for its blossoms as it is for the showy clouds of the fruits of the female plants. Usually found as a vine along fences or climbing on shrubs, the opposite leaves are the most distinctive feature in the Spring.

Later come the flowers, which are either male or female and found on separate plants. The flowers have no petals, but have sepals that form a cross or “X” below the stamens and pistils. The flowers are subtly different at first, with the female flowers showing a dense cluster of pistils in the center that are slightly taller than the surrounding infertile stamens. In the male flowers, the stamens radiate in a uniform manner, forming a hemisphere.

Clematis drummondii can be found in several places in and around my neighborhood, some of which are in walking distance of the community center. These photos were taken  near an intersection with the toll 45 frontage road in Williamson County.  Read more about Clematis.

About the Region

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
