The Fresno chili pepper (/ˈfrɛznoʊ/ FREZ-noh) is a medium-sized cultivar of Capsicum annuum. It is similar to the Jalapeño pepper but contains thinner walls. The fruit starts out bright green changing to orange and red as fully matured. A mature Fresno pepper will be conical in shape 2 inches long and about 1 inch in diameter at the stem. The plants do well in warm to hot temperatures and dry climates with long sunny summer days and cool nights.
