If you’ve stumbled across the name subterranean vetch (Vicia sativa amphicarpa), you might be scratching your head wondering what exactly this plant is all about. You’re not alone! This particular taxonomic designation is something of an enigma in the botanical world, with very limited information available in scientific literature.

Unfortunately, key details that gardeners typically want to know—like native range, growth habits, preferred growing conditions, and wildlife benefits—are not well-documented for this specific taxonomic name.
