What it is
Poblano Pepper (Capsicum annuum) is in the Solanaceae (Nightshade) family. Mild, heart-shaped chiles perfect for roasting and stuffing (chiles rellenos). Dried, they become anchos.
How to grow it
It wants full sun, water it even, and give it rich soil. Target a soil pH around 6.0-6.8. Space plants about 18 in apart. Expect roughly 65-80. Warm-season annual.
How it's used
Poblano Pepper is used: roasted, stuffed, dried (ancho).
🔎 How to identify it
- Bushy plant
- White flowers
- Large dark heart-shaped pods

How to grow & propagate poblano pepper
Everything I've worked out about starting this one, keeping it alive through a Texas year, and turning one plant into many — free.
How to propagate poblano pepper
Tomatoes, peppers, eggplant and their cousins are warm-season crops started inside 6–8 weeks before your last frost, then transplanted out once nights stay above 50°F. Tomatoes are the exception to most rules — you can bury the stem deep or root a side shoot (a 'sucker') in water to clone a plant mid-season. Potatoes skip seed entirely and grow from seed potatoes — chunks of tuber with an eye or two.
Growing poblano pepper in Texas
Give it full sun and rich soil. Match the spot to the plant and most of the battle is already won.
Time your planting to our long warm season and watch the frost dates at both ends; the live weather tool on this site is built for exactly that.
Keep moisture even, especially while it's young — deep, less-frequent soaks build better roots than a daily sprinkle.
Harvesting
Figure on roughly 65-80 before you're harvesting. Harvest at peak and keep harvesting — most vegetables produce harder the more you pick, and one left to over-mature tells the plant its job is done. The part you're after: ripe fruit.
Making more for free
Every seed we sell is open-pollinated, which means you can save your own from the best plants and it'll grow true next year. Let a few of your strongest plants finish and go to seed, dry it fully, and store it cool and dark. That's the whole point of heirlooms — buy once, grow forever.
