One of the most popular chilis in Mexico! 3- to 6-inch heart-shaped fruit is usually of gentle heat, at around 2000 Scovilles. Used green, after roasting and peeling, it is the classic pepper for chili rellenos. Dried, the fruit turns a rich dark red-brown and may be ground into an authentic red chili powder. Plants reach 2 feet or so and require a long season.
