Horizon bell pepper

[NarnianGarden]

Since falling for gardening, I've been trying to grow a couple of pepper plants each year... This season, I'm attempting Horizon (along with a mini & a red one), which someone kindly gave me seeds for last year.
From reading on-line, I'm getting it's a thick walled sweet variety, an OP. (I'm happy to see there is a yellow/orange variety other than the famous California Wonder which is available all over!)

Can anyone tell me a bit more and their experiences with this? Not much at Tatiana's database either, about the history, background etc.. I'd love to know a bit about this, and what makes it special/worth mentioning.

After search, I realized I had started a similar thread in January 2014
Is this a sign of getting old?
