It is a long, 8-inch pod that is tapered, with a horn-like shape. The pods mature from green to either red, orange or yellow, depending on the variety grown. I’ve included photos of the different varieties here. They are best picked when they have turned a deep red, yellow or orange. These plants were developed to bear fruit during cooler conditions, so they are excellent for higher zones with shorter growing seasons. They are suitable for outdoor or indoor growing. Here is the yellow variety. Here is the red variety. I typically use them as part of the Cajun Holy Trinity of onions, celery and peppers (as opposed to bell peppers). They are also great for making stuffed peppers. Also see:
