Tephrosia is a genus of flowering plants in the pea family, Fabaceae. The generic name is derived from the Greek word τεφρος (tephros), meaning "ash-colored," referring to the greyish tint given to the leaves by their dense trichomes.[2]
Uses
Many species in the genus are poisonous, particularly to fish, for their high concentration of rotenone. Tephrosia species have historically been used by indigenous cultures as fish toxins.[3] In the last century, several Tephrosia species have been studied in connection with the use of rotenone as an insecticide and pesticide.
Tephrosia is also one of the many beneficial legume trees that can be used in a permaculture food forest (also forest gardening) system as a source of living 'chop and drop' mulch.
