The jalapeno is the most popular hot pepper in America, and for good reason. Its plump, 3-inch pods start glossy dark green and ripen to bright red, delivering a medium heat of roughly 2,500 to 8,000 Scoville units with a crisp, grassy bite. It is endlessly useful, from fresh salsa and stuffed poppers to pickling and smoking into chipotles. Easy to grow and wildly productive, the jalapeno is the perfect first hot pepper for any garden.

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 small cage or stake for the bushy, fruit-laden plants. Pick pods dark green from about 70 to 75 days, or leave them to ripen red and sweeter.
Best tip
Jalapenos are one of the easiest peppers for beginners, but a couple of tricks make a difference. Start seeds indoors early and set plants out only once nights stay above 55F, then keep the water steady, because drought stress makes pods hotter and can trigger the harmless pale corking lines. In hot regions like Texas or Florida a little afternoon shade during heat waves helps blossoms set, and picking pods often keeps the plant cranking out more.
Jalapenos are the ultimate all-purpose hot pepper. Use them green for crisp, grassy heat in salsa, guacamole, nachos, and stuffed poppers, or pickle them for tacos and sandwiches. Let the pods ripen red for a sweeter, richer flavor, and smoke and dry them to make your own chipotles. Remove the seeds and ribs to dial the heat down for a milder kick.
How long do jalapenos take to grow?
Jalapenos are usually ready to pick dark green at about 70 to 75 days from transplant. Leave them on the plant another two to three weeks and they ripen to bright red, becoming a little sweeter and often slightly hotter.
How hot is a jalapeno?
Jalapenos land at a medium heat of roughly 2,500 to 8,000 Scoville heat units. Removing the seeds and white ribs tames much of the burn, while stress from heat and dry spells can make the pods hotter and cause the pale corky lines called corking, which is harmless.
Should I pick jalapenos green or red?
Both are great. Green jalapenos give the familiar crisp, grassy bite for poppers, salsa, and pickling. Red, fully ripe pods are sweeter and richer and are what is smoke-dried to make chipotles. Picking often keeps the plant producing more.
How big does a jalapeno plant get?
Plants are compact and bushy, usually 24 to 36 inches tall, and are heavy producers. A small cage or stake keeps a fruit-laden plant upright, and jalapenos also do very well in containers on a sunny patio.
