Groundnut Virginia
Arachis hypogaea subsp. hypogaea var. virginiensis
vegetableVirginia peanuts are a large-seeded cultivar of the groundnut, known for their substantial kernel size and excellent flavor. These legumes develop their pods underground after flowering, making them a unique crop that requires warm growing conditions and well-draining soil. They are valued for both fresh consumption and oil production.

Germination & Emergence
10-14 daysSeeds sprout and seedlings emerge with characteristic oval cotyledons. Young plants develop their first true leaves.
Keep soil consistently moist but not waterlogged. Maintain soil temperature above 65°F. Protect seedlings from birds and insects.
Vegetative Growth
40-50 daysPlant develops bushy foliage with compound leaves. Stems elongate and lateral branches form. Root system expands underground.
Ensure consistent watering and full sun exposure. Monitor for early pest damage. Avoid excessive nitrogen, which promotes foliage over pod development.
Flowering
30-40 daysSmall yellow flowers appear at leaf axils. After pollination, the flower stem (gynophore) elongates and pushes the developing ovary downward into the soil.
Maintain adequate soil moisture and calcium. Gently hill soil around plants to help developing pegs penetrate. Remove weeds that compete for resources.
Pod Development Underground
35-50 daysThe pegs (gynophores) penetrate the soil, and pods develop 1-2 inches below the surface. Pods expand with developing kernels inside.
Keep soil consistently moist but well-draining. Ensure loose, friable soil for easy peg penetration. Avoid soil compaction. Maintain calcium and boron nutrition.
Maturation & Harvest
Final 2-3 weeks before harvestPods reach full size and inner kernels mature. Plant foliage may yellow slightly. Pods are ready for harvest when inner pod cavity fills and shell hardens.
Reduce watering slightly as harvest approaches. Monitor soil conditions and dig test pods to confirm maturity. Harvest before first frost.

Common Pests
-
Hand-pick affected flowers; use Bt (Bacillus thuringiensis) sprays; deploy pheromone traps; encourage natural predators
-
Remove affected foliage; apply insecticidal soap; use Bt spray; maintain plant vigor
-
Spray with neem oil or insecticidal soap; increase humidity; remove heavily infested leaves
-
Apply fungicide (sulfur or copper-based); improve air circulation; remove infected leaves; rotate crops yearly
-
Maintain proper soil moisture and avoid stress; harvest timely; dry pods thoroughly (below 10% moisture); store in cool, dry conditions
Uses
Roasted snacking & confections
CulinaryVirginia peanuts are the preferred variety for in-shell roasting and are commonly used in candies, peanut brittle, and gourmet snack products due to their large, flavorful kernels. [source]
Peanut butter & spreads
CulinaryGround Virginia peanuts produce creamy, smooth peanut butter with excellent flavor. Their larger kernels yield more product and superior taste compared to smaller varieties. [source]
Cooking oil
CulinaryVirginia peanut oil is a high-quality culinary oil with a neutral flavor and high smoke point, ideal for frying, sautéing, and salad dressings. [source]
Nutritional supplement
MedicinalVirginia peanuts are rich in plant-based protein, healthy unsaturated fats, vitamin E, magnesium, and folate, supporting heart health and overall nutrition. [source]
Animal feed & bedding

Harvest Tips
Harvest when leaves begin to yellow and lower pods are mature (typically 120-150 days after planting, or 30-40 days after flowering ends). Dig carefully to avoid damaging pods; loosen soil around plants, then gently pull. Shake off soil and allow pods to air-dry in the sun for 2-3 weeks before shelling. Virginia peanuts are ready for harvest when the pod interior is fully filled and shells are hard.
Fun Facts
- 🌱 Groundnuts are unique among legumes because their pods develop underground; the flower stem elongates after pollination and pushes the developing ovary into the soil, where pods mature.
- 🌱 Virginia peanuts are the largest-seeded peanut variety and were named after Virginia, though they are now primarily grown in Georgia, which produces over 50% of U.S. peanuts.
- 🌱 Peanuts are actually legumes, not true nuts, and they fix nitrogen in the soil, making them an excellent rotation crop that improves soil fertility for subsequent plantings.
