History & Culture

The Fresno pepper was developed in 1952 by plant breeder Clarence Brown Hamlin in Fresno County, California. He aimed to create a chili suited for the Central Valley climate yet flavorful enough for fresh markets. The pepper gained popularity through canneries and Mexican-American grocers along the West Coast. As salsa culture spread nationally, Fresnos became a common substitute for Jalapeños when cooks wanted thinner skins and brighter ripe flavors. Today, they grow across the United States and appear in farmers' markets every summer.

Botany & Growing Notes

Fresnos thrive in warm, sunny gardens. Start seeds indoors 8 weeks before the last frost and keep seedlings at 24°C for rapid growth. Transplant when nights stay above 13°C. Plants reach about 60 cm tall and produce continuously if picked often. Provide well-drained soil, steady moisture, and light feeding every three weeks. Harvest green pods around 70 days after transplant, or wait another 10 days for red fruit. Containers of 15 liters or more work well on patios.
