I planted 3 SB7Js plants from the same seed source,
described as "Red Mushroom" pheno. They all have 3 different characteristics. 2 plants produced pods that started out green & ripened to kind of a dull red. One was very hot. One has almost zero heat. One of them was a dark plant with purple stems & leaf veins & produced pods that went from purple to pale yellow. No heat. Interesting the shape of all 3 plants are pretty uniform with such variance in color & pungency.
To further confuse things, I planted seeds from another SB7J plant described as "supposed to be red, but mine were yellow," but planted those much later. Those pods haven't ripened yet.
