Mammoth Jalapeño F1, Hot Pepper Seeds

Mammoth Jalapeño F1 — The Industry Standard for Size, Yield & Uniformity

When commercial growers need a jalapeño that performs season after season with unwavering consistency, they reach for Mammoth F1. At nearly 5 inches long and 1¾ inches wide, these pods are dramatically larger than any standard jalapeño — thick-walled, deeply green, and produced in heavy yields on vigorous plants all season long.

With 2,500–3,000 Scoville units, the heat is approachable without sacrificing that classic jalapeño flavor that belongs on everything from nachos to smoked brisket. Slice them fresh, pickle a batch, or smoke them low and slow — Mammoth delivers every time.

A Note on F1 Hybrids

Mammoth Jalapeño is an F1 hybrid variety, meaning seeds are produced by crossing two carefully selected parent lines. This delivers exceptional uniformity and vigor not found in open-pollinated varieties. Seeds saved from F1 plants will not reliably reproduce the parent traits — fresh seed is recommended each season for consistent results.

Growing Notes

Start indoors 8–10 weeks before last frost. Sow seeds ¼ inch deep in fertile, well-draining soil. Transplant outdoors after all frost danger has passed, spacing plants 18 inches apart in full sun. Water consistently and deeply. Harvest green for classic jalapeño flavor, or allow to ripen red for a slightly sweeter, hotter pod.
