'Tuck Tail Yellow' is a breeders mix hot pepper population from Kevin Bane in Cooley Springs, South Carolina. Part of his "Project Flamethrower," this extremely hot pepper population comes from a 4-way cross, the result of two unstable crosses crossed together (including 'Moruga Scorpion' x 'Fatalii Gourmet Jigsaw'). The same cross yielded Kevin's 'Alpha 1' population too.
The parent plant of these seeds was the only yellow-fruited plant resulting from the population — and it also had a tail like a scorpion, but folded inward and growing inside the pepper! Kevin said this one has an intense amount of heat, hotter than a ghost pepper at perhaps 1,200,000 Scoville units. The extremely hot peppers are also fruity tasting, and mix well with fruits like mango for hot sauces. Based on Kevin's experience, this population could prove incredibly diverse, or it could stabilize relatively quickly, but it'll take many generations to know for sure. And now you and your heat-loving friends can get in on the "Project Flamethrower" fun!
