The Mysterious Medicago lupulina var. willdenowii: A Botanical Enigma

If you’ve stumbled across the name Medicago lupulina var. willdenowii in your gardening research, you’re not alone in scratching your head. This particular variety of what appears to be related to the black medick family is something of a botanical mystery, with very little information readily available to home gardeners.

What We Know (And Don’t Know)

Here’s the honest truth: reliable information about Medicago lupulina var. willdenowii is remarkably scarce. While the genus Medicago includes well-known plants like alfalfa and black medick, this specific variety doesn’t appear in most standard gardening references or native plant databases.

The limited data available doesn’t clearly indicate:

  • Common names for this variety
  • Native range or geographical distribution
  • Whether it’s considered native, introduced, or invasive in any regions
  • Specific growing requirements or care instructions
  • Wildlife or pollinator benefits

A Word of Caution for Gardeners

When encountering a plant with such limited available information, it’s generally wise to proceed with caution. Without clear data on native status, invasive potential, or growing requirements, it’s difficult to make informed gardening decisions.

Better Alternatives to Consider

If you’re interested in members of the legume family that offer similar potential benefits, consider these well-documented alternatives:

  • Native clovers appropriate for your region
  • Wild lupines (where native)
  • Native vetches
  • Partridge pea (Chamaecrista fasciculata)

These alternatives have well-established growing guides, known benefits to pollinators and wildlife, and clear native status information.

The Bottom Line

While Medicago lupulina var. willdenowii might sound intriguing, the lack of reliable information makes it a risky choice for most home gardeners. When in doubt, it’s always better to choose well-documented native plants that you can grow with confidence, knowing their benefits and requirements.

If you’re determined to learn more about this variety, consider contacting botanical gardens, university extension services, or specialized plant societies who might have access to more detailed taxonomic information.
