Heirloom Cowpeas & Southern Peas: The Heat-Loving Powerhouses

Cowpeas (Vigna unguiculata) are the resilient survivors of the summer garden, offering a level of drought resistance and soil-building power that few other crops can match. At Firefly Farm & Mercantile, we curate a diverse selection of heirloom seeds from this versatile family, known variously as Southern Peas, Field Peas, or Crowder Peas. Whether you are growing classic Black-eyed peas or the spectacular, gravity-defying Asparagus Beans (also called Yard Long Beans), our non-GMO varieties thrive in the warm, sunny stretches of the Driftless Region summer. Not sure where to start, Whippoorwill is our top seller.Ā 

A Triple-Threat Harvest: Snap, Shell, or Dry

The beauty of the cowpea family lies in its culinary flexibility. You can harvest the young, tender pods to use as "snap" beans—especially our Asparagus Bean varieties which can reach lengths of nearly three feet! Alternatively, allow the pods to fill out for fresh "shellie" peas, or let them dry completely on the vine for a protein-rich winter staple. Beyond the kitchen, cowpeas are world-class nitrogen-fixers, working with soil bacteria to naturally fertilize your garden beds for future crops.

Quick Cowpea Growing Facts:

  • Planting Window: Wait for the heat! Direct sow only after the soil has warmed to at least 70°F (typically late May or early June in Wisconsin). They are very frost-sensitive.
  • Growth Habit: Our collection includes both compact bush types (Crowder peas) and vigorous climbers (Asparagus beans). Asparagus beans require a sturdy trellis at least 7 feet tall.
  • Drought Tolerance: Once established, cowpeas are incredibly resilient in dry conditions, making them a reliable choice for variable Midwest summers.
  • Soil Preference: Not picky! They thrive in poor soil and actually help improve it by fixing nitrogen.
  • Expert Tip: For the most tender Asparagus/Yard Long beans, harvest them when they are about the thickness of a pencil. While they can grow much longer, they are sweetest and most succulent at this stage!
