Straight from the man...

Actually it is a mystery, sprouted up in some parsley I grew in some recycled starting trays, I let it grow and it turned into the awesome brown podded pepper I call CPR. At first I thought it was from chocolate Primo seeds that someone sent & that didn't sprout, but after backtracking them it turns out that none of the seeds had sprouted and the original was crossed and became something different. Its obviously a cross from either Primo or Reaper therefore the name! Its going into f4 this season & has retained the same look, it is a bit hard to germinate but hopefully future generations will breed that out.
