Most I've ever grown was something like 17 varieties one season, between the bell and hot types.
Here's what happens on the Modoc when you try to grow peppers. Put these out the night of June 16th. 38F on the thermometer in the morning, at about 5' above ground level. Frost at ground level.
This little one with a black pot and gallon of water next to it just got stunted. It's still growing but less than a foot tall still.
Here's what they looked like the night before. Last frost in 2020 was on 17 June and the weather service didn't have a frost warning that night. I put the water jugs out to help just in case. Futile attempt as just about every plant frostburned. Tomatoes in there too. Couple of them were replaced, a couple are coming back now finally.
I replaced a bunch, and have one Carolina Reaper plant that hopefully will do OK. The heat we had stressed them some too, they're starting to come on now.
