Best Peppers to Grow in North Dakota

Zone 4 gardeners face unique challenges when growing peppers, but don't let the shorter season discourage you from growing these heat-loving plants. With an average last frost around May 10 and first frost by September 25, you're working with approximately 135 growing days – enough time for many pepper varieties if you choose wisely and use smart growing techniques. The key is selecting varieties bred for shorter seasons and cooler climates, rather than trying to coax long-season varieties to mature before frost.

When selecting peppers for Zone 4, prioritize varieties with days to maturity under 80 days and look for descriptors like 'early,' 'northern,' or 'short-season' in variety names. Sweet peppers like California Wonder and Cubanelle are reliable choices, while hot pepper enthusiasts can succeed with Early Jalapeño, Hungarian Hot Wax, and even some habaneros if started early enough indoors. The varieties listed here have proven themselves in northern gardens, offering good yields and flavor even when the growing season ends abruptly.
