How to Grow Cayenne Pepper From Seed

Updated July 2026

Cayenne is the classic pepper for serious, lasting heat. Its long, thin, wrinkled pods ripen to a brilliant glossy red and pack a sharp punch of roughly 30,000 to 50,000 Scoville units. Best known dried and ground into cayenne powder and crushed red pepper flakes, it is also the backbone of countless hot sauces. Prolific and easy to grow, a single plant yields enough fiery pods to season your kitchen for a full year.

Quick start

Start seeds indoors about 8 weeks before your last frost, kept warm at 75 to 85F. Harden the plants off, then transplant them out 18 to 24 inches apart once nights stay above 55F. Give full sun, steady water, and a stake or cage for the pod-laden plants. Pick pods fully red from about 70 to 80 days, then dry them for powder, flakes, and hot sauce.

Best tip

Cayenne is a productive, sun-loving pepper that rewards a long, warm season. Start seeds indoors early and transplant only after nights stay above 55F, then give it full sun and steady, deep water so the plant can ripen a big crop of pods fully red for drying. In hot regions the plants flourish; in cooler or short-season areas pick your warmest spot and be patient, since the best heat and color come from letting the pods ripen all the way on the plant.

Uses

Cayenne is the classic pepper for heat that lasts. Let the long, thin pods ripen bright red, then dry and grind them into homemade cayenne powder or crushed red pepper flakes, or simmer them into fiery hot sauce. Use the fresh pods to add a sharp kick to stir-fries, marinades, and pickles. A single plant yields more than enough to season a full year of cooking.

Frequently asked questions

How long does cayenne take to mature?

Cayenne pods take about 70 to 80 days from transplant to turn from green to their signature bright red. For drying and grinding into powder, let the pods ripen fully red on the plant before you pick them.

How hot is a cayenne pepper?

Cayenne is hot, roughly 30,000 to 50,000 Scoville heat units, well above a jalapeno or serrano. It brings a sharp, lingering heat that is why it is the classic pepper for hot sauces and dried cayenne powder.

How do I dry cayenne peppers for powder?

Harvest fully red pods and dry them whole in a dehydrator, a low oven, or by stringing them on a thread in a warm, airy spot until brittle. Once fully dry, grind them into homemade cayenne powder or crushed red pepper flakes.

How big does a cayenne plant get?

Cayenne plants grow bushy and productive, usually 24 to 36 inches tall, and load up with dozens of long, thin pods. Stake or cage them, because the sheer number of pods can weigh the branches down late in the season.
