Sesbania drummondii

Fabaceae (Leguminosae)

In Texas, rattlebox ranges from the North Central area into the Coastal Plain, growing on low wet grounds. It also goes into Mexico and east through Arkansas, Louisiana and Florida. Its evenly pinnate dull green leaves fold up in very hot sun. In its northern range the upper branches are likely to freeze down while the lower portion stays alive and woody. Although it is short lived, its showy racemes of yellow and red pea-like blossoms would provide an attractive ornamental planted in wet areas near streams. Inside its four-sided pod, the loose seeds rattle when the bush moves. Rattlebox is known to be poisonous to livestock and humans.
