If you’ve stumbled across the name Tephrosia subtriflora in your plant research, you’re likely wondering what exactly this mysterious species is all about. Well, you’re not alone! This particular member of the legume family (Fabaceae) is one of those plants that seems to fly under the radar, with limited information available even in botanical circles.
What We Know (And Don’t Know) About This Plant
Tephrosia subtriflora belongs to a genus of plants commonly known as hoary peas or fish poisons, though this specific species doesn’t appear to have a widely recognized common name. The genus Tephrosia includes over 400 species worldwide, many of which are valued for their ability to fix nitrogen in the soil and attract beneficial insects.
Unfortunately, detailed information about T. subtriflora’s native range, growing conditions, and garden performance is quite limited in available literature. This could mean several things: it might be a recently described species, have a very limited natural range, or simply hasn’t been extensively studied or cultivated.
