The Mystery of Tephrosia nitens

Tephrosia nitens belongs to the genus Tephrosia, which is part of the legume family (Fabaceae). However, finding reliable information about this specific species proves to be quite challenging. The name doesn’t appear in most major botanical databases or native plant resources, which raises some interesting questions about its current taxonomic status.

This could mean several things: the name might be a synonym for another accepted species, it could be a very localized or rare plant that hasn’t been extensively documented, or it might be an outdated name that’s no longer in use by the scientific community.

While we can’t provide specific details about Tephrosia nitens, we can tell you that the Tephrosia genus includes several native North American species that are worth considering for native gardens. These plants, commonly known as hoary peas or rabbit’s peas, are typically:

  • Herbaceous perennials or small shrubs
  • Members of the legume family, which means they can fix nitrogen in the soil
