The original Devil’s Tongue is a yellow variety developed by an Amish farmer in Pennsylvania. Later on a red variety emerged. It has a higher heat level than it’s yellow relative and a totally different flavor.
The pepper is a member of the Habanero family and possibly was developed from other Habanero strains and Fataliis. Like the fatalii red, this chile came from it’s yellow relative.
Devil’s Tongue Red plant will sometimes will produce yellow pods and even chocolate pods. Pods mature from light green to dark red and can get up to 3 inches long.
