What it is
Chiltepin (Bird Pepper) (Capsicum annuum var. glabriusculum) is in the Solanaceae (Nightshade) family. The wild mother of all peppers — a tiny, fiery native chile that birds spread, beloved across South Texas and shrugs off heat and drought.
How to grow it
It wants full sun to part shade, water it low once established, and give it well-drained soil. Target a soil pH around 6.0–7.5. Space plants about 24 in apart. Expect roughly Peppers in 90–120. Tender perennial (root-hardy).
How it's used
Chiltepin (Bird Pepper) is used: ripe red peppers.
🔎 How to identify it
- Small leaves on a wiry bush

How to grow & propagate chiltepin (bird 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 chiltepin (bird 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 chiltepin (bird pepper) in Texas
Give it full sun to part shade and well-drained soil. Match the spot to the plant and most of the battle is already won.
This one thrives in heat that flattens other plants, so it earns its space through a Texas summer. Get it established before the worst of July, keep water steady, and it'll produce when little else will.
Once it's rooted in, this is a low-water plant — overwatering does more harm than drought here. Water deeply to establish, then back off and let it prove how tough it is.
Harvesting
Figure on roughly peppers in 90–120 before you're harvesting. 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.
