Groundnut, Virginia
Arachis hypogaea subsp. hypogaea var. vulgaris
vegetableVirginia peanuts are a large-podded variety of cultivated groundnut known for their big kernels and excellent flavor, ideal for roasting and candy making. This legume develops its edible pods underground after the flower stem elongates and pushes into the soil. Virginia peanuts are warm-season annuals that require a long, frost-free growing season of 120-150 days.

Germination & Seedling
2-3 weeksSeed germinates in 7-10 days; cotyledons emerge and develop 2-4 true leaves. Seedlings are delicate and light green.
Keep soil warm (70-80°F) and consistently moist but not waterlogged. Thin seedlings to proper spacing. Ensure full sun exposure to prevent leggy growth.
Vegetative Growth
4-6 weeksPlant develops a bushy, compact growth habit with compound leaves and a deep taproot. Stems remain herbaceous and produce lateral branches.
Apply balanced fertilizer or light nitrogen (peanuts fix nitrogen but light feeding helps). Maintain consistent moisture and temperature above 65°F. Monitor for early pests.
Flowering & Pegging
6-8 weeksSmall yellow flowers appear in leaf axils (blooming starts 4-6 weeks after planting). After pollination, the flower stem (peg) elongates, bends toward soil, and penetrates into it where pods develop.
Ensure adequate calcium via gypsum application. Keep soil moist and loose to allow pegs to penetrate easily. Do not let soil crust over. Maintain steady warmth (75-85°F).
Pod Development & Filling
6-8 weeksPods develop 1-2 inches below the soil surface, typically containing 2-3 large kernels per pod in Virginia types. Pods become filled and shell hardens.
Water deeply during this critical stage but taper off as harvest approaches. Maintain mulch to keep soil cool and moist. Avoid excess nitrogen which delays maturity.
Maturity & Harvest
Ready to harvest when appropriate, typically 120-150 days totalFoliage yellows and dries; leaves drop. Pods fully mature, shells papery and brown. Kernels fully developed with pink or red seed coats (Virginia type).
Reduce irrigation 2-3 weeks before harvest. Check pod maturity by digging test plant: inner pod cavity should have brown vascular bundles. Harvest by pulling entire plant.

Common Pests
-
Plant resistant varieties; harvest at proper maturity; dry pods properly to <10% moisture; maintain good field sanitation; avoid stress conditions
-
Use resistant varieties; remove infected leaves; ensure good air circulation; avoid overhead watering; apply fungicide if severe
-
Handpick; use insecticidal soap; apply neem oil; encourage natural predators
-
Monitor with sticky traps; spray insecticidal soap; apply neem oil during flowering
-
Increase humidity by overhead irrigation early morning; apply miticide if populations high; encourage predatory mites
-
Rotate crops; use resistant varieties if available; practice solarization; avoid planting in infested soil
Uses
Roasted snack and peanut butter
CulinaryVirginia peanuts are prized for roasting whole due to their large kernels and rich flavor. They are also processed into creamy or chunky peanut butter, a staple protein-rich food worldwide. [source]
Candy and confections
CulinaryThe large kernels of Virginia peanuts are ideal for use in peanut brittle, peanut clusters, chocolate-covered peanuts, and other sweet treats where individual nut size and appearance matter. [source]
Heart health and protein source
MedicinalPeanuts contain resveratrol, monounsaturated fats, and plant-based protein linked to cardiovascular health and sustained energy. They are nutrient-dense legumes recommended in balanced diets. [source]
Peanut oil production
HouseholdPeanuts are cold-pressed or expeller-pressed to create cooking oil valued for its neutral flavor and high smoke point, suitable for stir-frying and deep-frying. [source]
Nitrogen fixation and soil amendment
CraftAs a legume, peanuts fix atmospheric nitrogen via root nodules, enriching soil naturally and reducing fertilizer needs for subsequent crops. Plant residue can be tilled back as green manure. [source]

Harvest Tips
Harvest when foliage turns yellow-brown (120-150 days). Dig carefully with a fork to lift the entire plant; shake off soil and allow pods to air-dry for 2-3 days in the sun. Pod maturity indicator: pull a test plant and check if inner pod cavity has brown vascular bundles (dark lines). Pods should crack slightly when bent. Cure dried plants indoors for 2-3 weeks before removing pods, or cure in warmth (100-110°F) for faster drying. Proper curing ensures good flavor and long storage.
Fun Facts
- 🌱 Peanuts are not true nuts but legumes that mature underground—after flowering, the flower stem (called a 'peg') pushes down into the soil where the pod develops, a process called 'geocarpy.'
- 🌱 Virginia peanuts are the largest-kerneled commercial peanut variety and are named after Virginia, a major peanut-producing state in the United States.
- 🌱 A single peanut plant can produce 10-40 pods, and each pod typically contains 2-3 kernels; Virginia varieties often produce 2-3 large kernels per pod compared to other types.
