A mature jalapeño fruit is 5 - long and hangs down with a round, firm, smooth flesh of 25 - wide.  Depending on cultivar, it can have a wide range of pungency, with Scoville heat units of a few thousand to as high as 462,884 (Chiltepín cultivar).  Commonly picked and consumed while still green, it is occasionally allowed to fully ripen and turn red, orange, or yellow.  It is wider and generally milder than the similar Serrano pepper.  The Chile Pepper Institute is known for developing colored variations.
