The Fatalii is a cultivar of the chilli pepper Capsicum chinense developed in southern or central Africa from chilies introduced from the Americas. It is described as having a fruity, citrus flavor with a searing heat comparable to the habanero, to which it is related and from which it may have derived.
 
The Scoville Food Institute lists the Fatalii as the sixth hottest pepper with Scoville units ranging from 125,000 ~ 325,000 units. The plants grow 20 to 25 inches in height, and plant distance should be about the same. The pendant pods get 2.5 to 3.5 inches long and about 0.75 to 1.5 inches wide.
