Okay, BC, noted that no confirmation on the black seed (code name 'man-am' ) just yet. I'll attempt to grow them to find out.
The 'mystery pack' thing is fun, I'll check germination of the others with cups. I love to test stuff. But I'm serious, if they sprout, they may have to grow in the 'wilderness.' My garden space is already overmaxxed, so I can't grow much that is unknown. My wife-unit already thinks I'm pepper crazy and way overboard already...
Your plants look great. When did you start growing them?
These are pictures of my two mystery plants.
#1
#2
#2 is my biggest plant and is growing great. #1 does not look very good. I hope it will keep growing.
I In my last update i wrote #1 looks like my Trinidad Scorpions. Now the look different. So i think, it's something else. It looks a bit like my Aji Limo Rojo now. But i guess (and hope) it's some totally different variety.
#1 is a chinense and #2 is a baccatum I believe. If I were to guess at all I would say that #1 is a Peruvian White hab just because my plants that grow white pods tend to have those chlorosis-like problems with early growth like you're having. My Fatalii Whites had the same problem this year and fixed themselves. Back off on the watering a bit and it should recover. Good luck!
