Since Mr. Taylor was considerate enough to name the thing CPR (Chocolate Primo Reaper), lets just run with that to skip the whole is the reaper is a rebranded primo argument. We'll call it the PR to describe the shape. I know there is a yellow PR because I grow it. I -think- there is an orange PR, but have not grown it. If someone has seeds for orange and needs yellow, lets trade. Anyway, the yellow turns almost orange as it goes to rot. I imagine the orange gets orange long before rotting but figure it might get more redish as it rots.
I don't think it is a stretch to think a seed source counted CPR seeds after YPR (see what I did there? seeds and one got stuck to his finger. So maybe it is a yellow PR that got mixed in. Just a thought. So lets see if we can count the PRs
CPR
YPR
RPR
OPR
Thumbs up to Mr. Taylor for giving us the new way to describe the shape. I do grow reaper and primo of different colors as different lines, but I am culling for the same attributes so each year they look more and more alike. I think other folk have been doing the same.
