South Dakota in USDA Zones 3–5
South Dakota spans Zones 3–5. Variety lists below are organized by zone — start with your zone for the most accurate recommendations.
Growing Peas in South Dakota
Zone 4 gardeners have a sweet spot for growing peas, despite the challenges of late frosts and shorter growing seasons. The cool springs and moderate summers create ideal conditions for these cool-season crops, which actually prefer temperatures between 55-70°F. Your late May 10th frost date means you'll need to be strategic about timing, but the payoff is worth it – peas grown in cooler climates often develop better flavor and stay productive longer than those in warmer zones.
When selecting pea varieties for Zone 4, prioritize cold tolerance, disease resistance, and days to maturity. Look for varieties that can handle light frosts and cool soil conditions, as you'll often be planting when soil temperatures are still in the 40s. Heat tolerance is equally important since you'll want varieties that won't bolt immediately when summer temperatures climb. The varieties listed here have proven themselves reliable performers in Zone 4's unique conditions.
Your 135-day growing season is actually generous for peas – long enough for succession planting and even fall crops. The key is choosing a mix of early varieties like Sugar Ann and Kelvedon Wonder for quick harvests, mid-season workhorses like Green Arrow and Lincoln for main crops, and heat-tolerant varieties like Wando for extended harvests into summer.

Zone 4 Growing Tips for South Dakota
Start your first pea planting 4-6 weeks before your last frost date, which puts you in early to mid-April for Zone 4. Peas can germinate in soil as cool as 40°F, though they'll emerge faster when soil reaches 50°F. Don't wait for perfect conditions – peas actually prefer cool, moist soil and can handle light frosts down to about 28°F once established. For insurance, keep row covers handy for unexpected late cold snaps.
Succession planting every 2-3 weeks through early June will give you continuous harvests. Plant your last crop about 10-12 weeks before your first fall frost (mid-July for most Zone 4 areas) for a fall harvest. This timing lets you take advantage of cooling September weather, when peas often produce their sweetest pods. Fall-planted peas frequently outperform spring crops since they mature in ideal cool conditions rather than struggling against increasing heat.
Zone 4's biggest challenge is the transition from cool, wet springs to hot summers. Mulch heavily once soil warms to keep roots cool, and consider planting taller varieties on the north side of your garden where they'll get afternoon shade. Don't skip the inoculant when planting – the beneficial bacteria help peas fix nitrogen and establish better in cool soils.
