U.S. Status
Endangered, Listed 9/28/1988
Description
The large-fruited sand-verbena has stems up to 20 inches tall covered with sticky hairs. It has round clusters of pink-purple flowers up to 4 inches across.
Life History
Rosettes appear in the fall, and the plant flowers from March through June. The flowers open late in the afternoon, and have a sweet odor that increases toward evening. At night, moths help this plant reproduce by spreading pollen from plant to plant. Yaupon and grape are plants which provide food for the moth larvae, so the presence of these food plants in the habitat is important. The entire above-ground portion of the plant dies back during the heat of the summer.

The large-fruited sand-verbena is endangered because many areas of sandy soils have been cleared of native vegetation and planted to pasture grasses. Construction of housing developments and oil wells has also destroyed or changed its habitat (open areas of deep sandy soil).
Habitat
It lives in sandy openings in post oak woods.
Distribution
This plant is distributed in Leon, Robertson, and Freestone Counties.
