Interesting piece of detective work on the blog, thanks for posting it, Andrey! I must have missed the article the first time around. I never grew Enjoya out beyond the disappointing M2 yellows (M=mine: at least that's how I've used it when saving dubious seed from an unknown source, tickled to see M instead of F in the article as well.) While choosing this year's pepper seeds, I found I still have quite a few of the original seeds saved from the striped grocery store pepper tucked away in my box. I grew out the nice big yellows, but a bit too long season for me.
Has anyone noticed if the striped Enjoyas are still showing up in the markets anywhere?
