What is Crotalaria?

Crotalaria is a leguminous flowering plants genus. Rattlepods is the Crotalaria common name. The plant belongs to the legume Fabaceae family and Faboideae sub-family. Crotalaria species include about 500 shrubs and herbaceous plants.

Most Crotalaria varieties are native to Africa. About 400 plant species native to Africa grow in wet grasslands, especially depressions, flood plains, fields and roadsides, along rivers and swamps, and deciduous bushland. Certain Crotalaria species are used as ornamental plants.

Crotalaria Etymology

Also known as rattlebox, the name rattlepod was derived from the nature of the seeds to loosen as they mature in the pods. The loose seeds make a rattling sound whenever the pods are shaken. The name was obtained from an Ancient Greek word for 'castanet'. Crotalaria is similar to the rattlesnakes genus Crotalus.

Australian Crotalaria species are cultivated as grain crops. They thrive in soils poor in nutrients, dry environments and agricultural systems with low inputs. The Crotalaria plant species in Australia grow upright, bear flowers and fruits on the edges of branches, and neither shatter nor tend to dehisce. The seeds are either moderate or large for easy harvesting.

Sunn hemp or Crotalaria juncea is grown in the subtropics and tropics regions for lightened fiber, green manure and fodder. It's also a potential source of cellulosic ethanol for generating biofuel.

Popular Crotalaria Species

  • Crotalaria pallida
  • Crotalaria spectabilis
  • Crotalaria pumila

  • Crotalaria ochroleuca
  • Crotalaria brevidens

Crotalaria ochroleuca and brevidens are grown in western Kenya. They are consumed by luos, luyhas and kisii tribes. Apart from doing well in poor soils and being disease resistant, the two Crotalaria species are used as cover crops. They point to the fact that tribes in Kenya began cooking vegetables as a nutritious source of nutrients.
