Anaheim pepper, aka New Mexico or California pepper, is a mildly hot, thick-walled pepper, used for making chili rellenos and when dried, is often the variety used for making strings of dried peppers common in New Mexico. Peppers can be used green, but they will turn a bright red when fully mature. With nighttime summer temps in the Pacific NW typically dropping below 75 degrees at night, Anaheim pepper plants will provide a fairly continuous supply of fruits throughout the summer months.
