What Makes Survival Garden Seeds Different - non-GMO heirloom seeds

Knuckle Purple Hull Cowpea Seeds from Survival Garden Seeds deliver a productive, reliable bush-type cowpea ideal for warm-season gardens. Named for their large, richly colored purple pods, these plants produce plump, succulent peas with a distinctive purple “eye.” Known for their dependable yields and easy-growing nature, Knuckle Purple Hull cowpeas offer gardeners a versatile, nutrient-rich crop that shines whether eaten fresh or preserved for later use.

Heavy Yields and Excellent Flavor:
This long-loved variety is prized for its abundant harvests and creamy, tender peas. When fresh, the cowpeas display a vibrant green tone accented by a purple eye, offering both visual appeal and rich, satisfying flavor. They maintain their taste and nutritional value exceptionally well when frozen, canned, or dried, making them a dependable option for year-round meals and pantry storage.

Bush-Type Convenience:
Knuckle Purple Hull cowpeas grow on compact, bushy plants that require minimal support and are easy to manage in both garden beds and larger containers. Their sturdy growth habit, combined with strong productivity, makes them a smart choice for gardeners who want a low-maintenance, high-reward legume.

Why Customers Love Knuckle Purple Hull Cowpeas:

  • Bush-type plants that produce heavy, reliable yields
  • Large purple hulls filled with plump, tender cowpeas
  • Sweet, creamy flavor suited to fresh eating or preserving
  • Retains quality well when frozen, canned, or dried
  • Nutritious legume rich in protein and ideal for warm climates

How to Grow:
Sow seeds directly in the garden after the last frost once soil has warmed. Choose a full-sun location with well-drained soil. Water consistently during early growth, then reduce watering as plants mature, as cowpeas are naturally drought-tolerant. Harvest when pods are well filled and peas are still tender for fresh eating, or allow pods to mature fully on the plant if preserving for later use.
