Chiltepin pepper plants

The peppers nobody domesticated, and the ones birds planted.

By Debra Austin

What a wild pepper is

Everything else on this site was shaped by people choosing which plant to save seed from. These were not. Chiltepins grow on their own across northern Mexico and into south Texas, and the plant you buy is the plant that evolved, not a selection of it.

The chiltepin is the wild form of Capsicum annuum, which makes it the ancestor of the jalapeño, the bell pepper and most of the supermarket shelf. The other wilds we carry are different species entirely: chacoense out of the Bolivian Chaco, flexuosum and friburgense out of Brazil's Atlantic forest.

Chiltepin, tepin, pequin

Tepin and chiltepin are the same plant. Chiltepin comes from the Nahuatl chiltecpin, and the pod is a small round berry, roughly pea-sized.

Pequin is not the same thing. The pod is longer, closer to an oval or a small cone, and the plant is usually taller and more upright. Both are wild annuums, both are fierce for their size, and seed sold under either name is frequently the other one.

The birds did this

Birds cannot taste capsaicin and mammals can, which is the entire point of the chemical. Birds eat the fruit whole, the seed passes through intact, and the plant travels. Mammals chew seed to pieces, so the plant spent a few million years making itself unpleasant to them.

That is why wild pods sit upright on the plant and ripen bright red. They are advertising to something with wings.

How hot a chiltepin is

Wild pods hit fast and fade fast. The number varies by plant, which is why this page shows the range from the varieties we list instead of one folk figure. A pequin is the longer pod and it is easy to buy by accident. Its page is separate.

Growing them, and being patient

Wild seed germinates slowly and unevenly. Three weeks is normal, longer is common, and a tray that looks dead often is not. The plants stay small and woody, take shade better than a domesticated pepper, and live for years if you bring them in.

The heat is real but it is a flash rather than a build. It arrives fast and leaves fast, which is why a chiltepin goes into a salsa whole rather than chopped through it.

The Chiltepins and Wild Peppers we grow

Questions people ask

Is a chiltepin the same as a tepin?

Yes. Chiltepin, tepin and chile tepin all name the same wild round-podded Capsicum annuum. Pequin is a different, longer-podded wild annuum.

Why is wild pepper seed so slow to germinate?

Wild species have not had that trait bred out of them. Three weeks or more is normal, and germination is uneven on purpose: staggering it is how a wild plant hedges against a bad season.

Are wild peppers hotter than domesticated ones?

For their size, yes, and the heat hits faster and fades faster. The range across the wild varieties we stock is shown above.

Do chiltepins come back every year?

They are perennial and woody. Kept above freezing, under a light or in a bright window, a chiltepin will keep going for years.
