As the Center for Plant Conservation custodian for endangered plants in South Texas, the Botanical Garden plays an important role in assuring that these regional plants do not face extinction. One such plant includes the Prostrate milkweed, Asclepias prostrata, a member of the dogbane family that is known from just three counties (Zapata, Starr and Hidalgo) in deep South Texas and adjacent Mexico.
Just a few populations are known to occur in Texas, with most of these occurring on public lands in Zapata and Starr counties. Because of their cryptic and ephemeral nature, these plants are often overlooked, or not seen during surveys.
In order to conserve this species, the rare plant conservation and research section of San Antonio Botanical Garden, working with the Center for Plant Conservation, maintains a living collection of prostrate milkweed. Each season seed is collected, cleaned and then stored for future use. To date, no wild collected seed has been deposited in our seed bank. Access to additional private land in deep South Texas is needed to ensure the survival of these plants in Texas. - Michael Eason, Director of Plant Conservation and Research, @sabotgarden
