For the pepper experts: I have a Cayenne Pepper plant that has a large pepper on it (~7-8") but it's not ripening. It's been a couple weeks since I've seen any change in size but it hasn't shown any change in color. Another pepper on the same plant has turned a birght red, as it's supposed to do. I planted it next a to Jalapeno plant so is it possible that that flower cross-pollinated and will therefore not turn red?
