Last year I grew the "Long Red Slim Cayenne" variety, which produced well, and I had far too many plants... I wasn't crazy about the taste or heat and got sick of them quick. I've honestly had jalapenos that were hotter. Which leads me to wonder... are there *any* cayennes that are worth growing again? As in, for heat and flavor? I like the look of that big, fat cayenne on Wikipedia's article on cayenne peppers, but for all I know it could be the same as the one I had, except for shape and size... then again, hell, I'd be tempted to grow that one purely for looks if it consistently produced pods that looked like that!
