All are upright growing summer annuals. Stems are coarse and well branched except in thick stands. Leaves are trifoliate, the leaflets varying in shape from linear to ovate. Crotalarias are adapted only to warm climates with a long growing season. They are resistant to the rootknot nematode and are valuable to reduce the nematode population in infested soils. They do well on soils of low fertility and are most used to turn into the soil for soil improvement. C. spectabilis contains an alkaloid poisonous to livestock. The other three species can be used for pasture or silage though palatability is low. According to the 1960 census, seed was harvested in 1959 from 2,657 acres in this country, and sufficient seed was produced to plant around 35,000 acres.
