Lespedeza: The Mystery of Lespedeza potaninii

If you’ve stumbled across the name Lespedeza potaninii in your plant research, you’re not alone in wondering about this elusive member of the lespedeza family. Here’s the thing though – this particular plant name exists in something of a botanical twilight zone, making it quite the puzzle for gardeners seeking reliable growing information.

The Name Game Challenge

While lespedeza is indeed a well-known common name referring to a genus of leguminous plants, Lespedeza potaninii appears to be either an extremely rare, misidentified, or invalidly published species name. In the botanical world, this happens more often than you might think! Plant names can get mixed up, misapplied, or exist only in limited references without proper scientific validation.

What We Do Know About Lespedeza

The Lespedeza genus includes many wonderful plants, commonly known as bush clover or lespedeza. These plants are typically:

  • Attractive flowering perennials or shrubs
  • Members of the legume family (they fix nitrogen in soil!)
  • Often valuable for wildlife and pollinators
  • Adaptable to various growing conditions

The Geographic Mystery

Without verified information about Lespedeza potaninii’s native range or distribution, we can’t provide a reliable geographic overview or native status. This uncertainty makes it impossible to recommend the plant based on native gardening principles.

Should You Plant It?

Here’s our honest recommendation: until more reliable information becomes available about Lespedeza potaninii, it’s better to choose well-documented lespedeza species instead. Why gamble with an uncertain plant when there are fantastic, proven alternatives available?

Better Lespedeza Alternatives

Consider these well-established lespedeza options instead:

  • Native Bush Clover (Lespedeza violacea) – A fantastic native option for North American gardens
  • Korean Lespedeza (Lespedeza stipulacea) – Annual species good for wildlife
  • Shrubby Bush Clover (Lespedeza bicolor) – Showy purple flowers, though not native

The Bottom Line

While the mystery of Lespedeza potaninii remains unsolved, don’t let that discourage your lespedeza dreams! The genus offers plenty of wonderful, well-documented species that can bring beauty, wildlife value, and nitrogen-fixing benefits to your garden. Sometimes in gardening, the best choice is the one you can actually find reliable growing information about.

When in doubt, consult with local native plant societies, botanical gardens, or extension services. They can help you identify the best lespedeza species for your specific region and garden goals. Happy gardening!
