Two C. annuum from Mexico that nobody confuses on the shelf and everybody confuses in the heat conversation. The Poblano is the large, heart-shaped pod from Puebla. The Jalapeño is the short, thick, cylindrical pod named for Xalapa in Veracruz. Oregon State University Extension gives the Poblano as 3 to 4 inches wide by 4 to 7 inches long and the Jalapeño as 1.5 inches by 3 inches. That size difference decides almost everything about how each is used.
The Poblano is the stuffing pepper. Thick walls and a wide cavity make it the classic choice for chiles rellenos, and roasting loosens its tough skin, which is why it is nearly always roasted before anything else happens to it. Dried, it changes name. The ripe red pod becomes the ancho, and a darker dried form is the mulato.
The Jalapeño is the everyday pepper. Green and raw it is grassy and crisp. Pickled and sliced it sits on nacho plates. Smoked and dried it becomes chipotle. Texas named it the official state pepper in 1995.
Puebla has one more claim on this page. The oldest unambiguous chili remains sit in preceramic layers of dry caves in the Tehuacán Valley of Puebla, and central-east Mexico is the most likely region where C. annuum was first cultivated (Kraft et al. 2014). The Poblano is a modern pepper, not that ancient one. But it grows in the state where the whole story started.
