Jerry, I think you didn't get very well what's the situation
I think you've seen the post from Ontosoroh on the pitcherplants.com forum. A few years ago he found at a local market this great form of N. rafflesiana, with a red and black peristome. He nicknamed his plant "blood red", but that's just a nickname, given to a single specimen. So unfortunately you can't just ask for a rafflesiana "blood red" in a forum, hoping to have his same plant
IF in the future he will be able to take cuttings, hopefully the plant will spread in cultivation. Otherwise you can only hope to find somewhere else a plant with that same characteristic, but consider that it's the first time in 25 years that I see a rafflesiana with such a peristome! Anyway, who knows...
