Sesbania herbacea (syn.Sesbania exaltata) is a species of flowering plant in the legume family known by the common names coffeeweed, Colorado River hemp, and bigpod sesbania. It is native to the United States, particularly the southeastern states, where it grows in moist habitat. It can be found elsewhere as an introduced species. It is a woody herb growing to 3 meters or more in height. The leaves are made up of many pairs of oblong leaflets. The inflorescence is a small raceme of pealike flowers with yellow or purple-spotted petals.
Erect, annual or briefly perennial, herbs, shrubs or small trees. Indumentum simple. Stipules and stipels usually present. Leaves paripinnate. Leaflets opposite or subopposite. Flowers in axillary racemes. Calyx campanulate, teeth subequal, shorter than tube. Corolla glabrous, the standard petal with variously shaped appendages. Stamens diadelphous, 1 free, the others with filaments which are joined below to form a sheath (the filament sheath) which encloses the style, and which are free above. Pod usually long, dehiscent, beaked, sometimes winged, transversely septate.
