proof of variation within a theme,the purple one im almost sure is a mutation(THE PURPLE ONE), but the red one may or may not be a mutation and may or may not be a cross, because red tends to be a dominant gene color and is present within all chocolate and other color peppers as well and the red gene can become dominant at any given time
my friend has noticed this with Congo chocolate Habs that i think where isolated,some plants exhibited red pods
that purple one is a beautiful plant and deserves to have seed saved from it for future generations, im sure there may even be a few on here that would be interested in some if you where willing to part with them
thanks your friend Joe
