Black-Eyed Pea is an annual grown for its pods, ready to pick about 70 days after sowing. It's hardy across USDA zones 3 through 12 and handles dry spells once it's established. Its summer flowers are a moderate draw for honeybees and native bees, even though the pods are the prize. A heavy nitrogen-fixer, it draws nitrogen from the air and feeds it back to the soil — turn it under or leave the roots in place, and the next planting inherits a richer bed.

What Black-Eyed Pea is
Black-Eyed Pea grows as an annual and reaches around two feet at maturity. It blooms purple in summer.
How to grow Black-Eyed Pea
Black-Eyed Pea grows in USDA zones 3 through 12 and is ready to harvest about 70 days after planting. Black-Eyed Pea does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4 to 8.8, on well-drained ground. It needs around 2,000 growing degree days to mature and a growing season of at least 30 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant black-eyed pea in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Black-Eyed Pea prefers pH 4 to 8.8 (USDA PLANTS Database). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band. It fixes its own nitrogen, so skip the high-nitrogen feed and instead dust the seed with a matching rhizobium inoculant at sowing.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at maturity
Black-Eyed Pea is ready about 70 days after sowing (SARE; USDA-NRCS). Pick the pods young and tender, before the seeds inside fully swell.

Where Black-Eyed Pea thrives
On hardiness alone, black-eyed pea grows across most of the country — its range (USDA zones 3 through 12) is unusually wide. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

Frequently Asked Questions
Can I grow Black-Eyed Pea in my zone?
Black-Eyed Pea grows in USDA hardiness zones 3 through 12 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
How long does Black-Eyed Pea take to grow?
Black-Eyed Pea is ready to harvest about 70 days after planting (SARE; USDA-NRCS). Your local frost dates and soil temperature move that window earlier or later.
When should you plant Black-Eyed Pea?
Most growers plant black-eyed pea after the last spring frost, once the soil has warmed, leaving enough of the season for its 30-day frost-free need. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Black-Eyed Pea need?
Black-Eyed Pea needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Black-Eyed Pea need?
Black-Eyed Pea prefers soil pH 4 to 8.8, on well-drained ground (USDA PLANTS Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Black-Eyed Pea attract pollinators?
Yes — black-eyed pea's flowers are a solid nectar source for honeybees and native bees (Xerces Society, Pollinator Partnership).
Is Black-Eyed Pea safe for pets?
Black-Eyed Pea is not known to be toxic to dogs or cats based on available data (ASPCA). Always supervise pets around new plantings.
