Lindheimer Senna is an upright perennial that reaches three to six feet in height. It can be found in dry, rocky limestone soils of the Edwards Plateau and the South Texas Plains. The velvety leaves are divided into four to eight pairs of leaflets. Each leaflet is one to two inches long and 3/8 to 3/4 inches wide. The flowers are 1 1/4 inches in diameter and consist of five yellow-orange petals. Lindheimer Senna blooms from June to October. It is known to be a strong laxative when the leaves are brewed into a tea. It can also be toxic if eaten by livestock and the symptoms are diarrhea, weakness, dark urine, and death. Most animals that are poisoned by Lindheimer Senna do not recover. |
