Seedling
2-3 weeksSeeds germinate in 7-10 days in warm soil (70°F+). First leaves emerge as cotyledons followed by true compound leaves.
Keep soil consistently moist but not waterlogged. Thin seedlings if overcrowded. Warm soil is critical.
Vegetative Growth
3-4 weeksPlant develops bushy foliage with compound, trifoliate leaves. Stems become sturdy and plant reaches 12-24 inches tall depending on variety.
Provide full sun exposure. Support with stakes or allow to sprawl. Minimal fertilizer needed due to nitrogen fixation.
Flowering
2-3 weeksSmall white, pink, or purple flowers appear along the stems. Flowers are followed by developing pods.
Consistent moisture is important during flowering to prevent flower drop. Continue full sun exposure.
Pod Development & Filling
3-4 weeksPods elongate and swell. Purple coloring develops on hulls. Peas inside mature from soft to firm.
Reduce watering frequency; let soil dry slightly between waterings. Monitor for pests.
Harvest Readiness
2-4 weeks of active harvestingPods reach full length (6-7 inches) with firm, cream-colored peas inside. Purple hull coloring is prominent.
Pick regularly to encourage continued production. Harvest in early morning when pods are firm.

Harvest Tips
Harvest pods when they are 6-7 inches long and still tender, before they become too mature and tough. The purple hull coloring indicates readiness. Harvest early and often to encourage continuous pod production. Pick in the morning when plants are cool. Can be harvested fresh for shelling or allowed to dry on the plant for dry peas.
Fun Facts
- 🌱 Purple hull peas are an African heritage crop deeply rooted in Southern US foodways, particularly important in the culinary traditions of enslaved and Black communities.
- 🌱 These peas belong to the cowpea family (Vigna unguiculata), which originated in Africa and are more heat and drought-tolerant than snap peas or garden peas.
- 🌱 The purple hull coloring is a natural pigment (anthocyanin) that develops as the pod matures and can indicate peak tenderness for harvest.
