King Of The North is my favorite.

I like Purple Beauty but it's small. It turns from green to purple to bright red.

I like Staddon's but it doesn't always produce well here because of our weather.

Certain strains of Chocolate are excellent. I get mine from Fedco because I can count on the strain they offer to produce well.

I really find that hybrids do best. Great luck with Fat& sassy for a red bell, and great with golden summer for a yellow. This season I tried my first purple bell, used 'Tequila'(starts out purple, then ripens orange-red), and they were a customer stopper on the table. In a mixture with yellow and red, had great sales.
