Conditional — Some Areas
field pea (zones 2-10) has limited zone overlap with Tennessee (6a-7b). Only zones 6-7 in the state are suitable.
Your yard isn't the whole zone.
Field Pea is grown as an annual, so your winter zone isn't the deciding factor — your frost-free window is, and slope, trees, and low spots move the last-frost date across a single yard. Enter your address and we'll score field pea against your parcel's actual frost dates, sun, and soil.

When to Plant Field Pea in Tennessee
The frost window
Across Tennessee, the last spring frost clears between Mar 20 and Apr 20, and the first fall frost lands between Oct 10 and Nov 5 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 173-day window you can count on — up to 230 days on a mild site in a kind year.
Frost tenderness
Field Pea is frost-tender — its listed minimum temperature is 39.2°F (USDA PLANTS Database) — so set plants out after the last frost has cleared your local site, not the state's earliest date.
Days to maturity vs. the window
At 70 days to maturity (USDA PLANTS Database), a planting right after last frost ripens with 103 days to spare even in Tennessee's tightest frost scenario — room for a later start or a second sowing.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Field Pea wants 60+ frost-free days; a typical Tennessee site sees ~220 (NOAA Climate Normals). That leaves comfortable headroom for succession planting.
Growing degree days
Field Pea needs ~1000 GDD (base 50°F) to ripen. The state median runs ~4200 GDD (USDA NRCS county aggregates), so Tennessee's typical season clears that easily.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Field Pea likes near-neutral soil (pH 4.5-8.3). That's the common-ground band across Tennessee's silt loam and clay loam — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Tennessee site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider
Zone compatibility tells you about winter cold survival — but Tennessee growers also need to think about:
Heavy clay soils in the Nashville Basin
Basin clay is fertile once it drains — a raised bed handles that immediately, and yearly compost makes it permanent.
High humidity promotes disease in summer
Morning base-watering, breathing room between plants, and resistant varieties — the humid-summer basics from your extension.
Variable spring weather with late frost risk
Let your local frost normals set the schedule — Tennessee springs reward the growers who wait out the last cold snap.
Pollinator + Wildlife Value
Field Pea draws pollinators (low value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.
Tennessee Cooperative Extension
For Tennessee-specific cultivar recommendations, planting calendars, and pest pressure for field pea, the canonical source is UT Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Field Pea native to Tennessee?
No — the USDA PLANTS Database lists Field Pea as introduced rather than native in the Lower 48, so it is not part of Tennessee's native flora. It grows here as a garden plant; pairing it with a few Tennessee natives keeps local pollinators fed too.

Common Questions About Growing Field Pea in Tennessee
When can I plant Field Pea in Tennessee?
Tennessee's last spring frost clears between Mar 20 and Apr 20, and the first fall frost lands between Oct 10 and Nov 5 (NOAA Climate Normals 1991-2020). Field Pea is frost-tender — its listed minimum temperature is 39.2°F (USDA PLANTS Database) — so wait until the last frost has cleared your specific site before planting out.
Can Field Pea mature before first frost in Tennessee?
Yes — Field Pea matures in 70 days (USDA PLANTS Database), and Tennessee's dependable frost-free window runs 173 days (NOAA Climate Normals 1991-2020), leaving 103 days of margin. Plant just after last frost and it ripens ahead of the first fall frost.
What hardiness zone is Field Pea grown in across Tennessee?
Tennessee spans USDA hardiness zones 6a-7b (USDA ARS PHZM 2023). Field Pea carries a range of zones 2-10, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Tennessee site have?
A typical Tennessee site sees ~220 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Field Pea needs 60+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Field Pea native to Tennessee?
No — the USDA PLANTS Database lists Field Pea as introduced rather than native in the Lower 48, so it is not part of Tennessee's native flora. It grows here as a garden plant; pairing it with a few Tennessee natives keeps local pollinators fed too.
How should I amend the soil for Field Pea in Tennessee?
Field Pea prefers pH 4.5-8.3 and well (dry spells) drainage (USDA PLANTS Database). That sits in the common-ground band across Tennessee soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Field Pea actually grow on my specific land in Tennessee?
