I have not grown this plant. Other common names for this deciduous, low-growing ground cover or subshrub are fern acacia, texas acacia, prairie acacia, Texas prairie acacia, whiteball acacia and prairie guajillo. It grows in full sun to partial shade and can be found on calcareous grasslands, rocky slopes and open woodlands. In Texas, it can be commonly found in the eastern two thirds of the state with it being it less common in west Texas. There are 3 identified varieties in Texas: var. hirta (A. hirta) - grows in east and central Texas; var. texensis (A. texensis) - grows in south Texas and the Trans-Pecos where it overlaps with var. chisosiana and var. chisosiana - found in S. Brewster and Presidio counties.
The fern-like foliage that folds together when touched, at night or with strong vibations. The small white round flowers appear from summer into the fall and are followed by 2- to 3-inch seed pods. It can spread laterally from its roots and the stems do not have thorns. Livestock and white-tailed deer enjoy browsing upon it. It is similar in appearance to Illinois bundleflower, Desmanthus illinoensis, but the leaf and fruit structures are different. It has a very deep growing taproot as do other acacias.
To control its growth and/or keep it compact, mow or trim it in the winter when it dies back. It can be used for soil erosion control and is a suitable plant for xericapes, wildscapes and rock gardens.
