I've also got Black Congo and Brown Congo in there too. LOL Both from Peppermania. Is anyone growing Royal Gold - C.Chinense peppers? Are they supposed to have a lot of that purple red color on the leaves? Mine does but so does a couple other different plants that I think the southern exposure and 70-80 degree days has something to do with. The Royal Golds have Chinense,heart shaped leaves but Black pearl colored with olive drab mixed in. The seeds came from Peppermainia too. Cool looking 2 inch plants going on their 3rd or 4th set of leaves. I think I'll sprout another one and see if it's the same. If they stay that way the pods will really stand out when they get ripe.They'll glow against the dark background. I tried taking pics but the camera I have doesn't get clear pics of something that small-close ups are blurred. I'll take some more in a few weeks.

I wouldn't eat any ornamental from a store. Since they aren't sold for eating but as an ornamental the nursery can use all kinds of stuff on the plant that you can't use on edibles.Systemic and other poisons that stay in the plant a long time etc. Grow seeds from it and then eat the peppers from that plant. Ornamentals are OK to eat but a lot of them are super hot with little flavor or not hot at all with no flavor. Only way to find out what yours tastes like,unless it's organically grown is to grow your own and try a few pods.

Overwintering is probably a pretty big challenge for a new pepper grower. You could do as you say, just try one and see what happens with the plan to start seed in winter. Would be best though to get an established plant from somewhere if possible as your experience with starting seed so late will not really teach you how to grow peppers as timing is everything with peppers. I time mine to have a major flowering in May/June before the summer heat kicks in which can cause abortion of flowers. This allows me to harvest near end of July, after which another major flowering happens when past the worst of the heat that ripens before frost. If I'm lucky, I'll get more then that, but I can't depend of flowers formed in July to germinate due to high temperatures.

The issue is that most peppers categorized as "super hot" are of the chinense species. Thai chiles and cayennes are from the annuum family which have the taste you're looking for but don't typically get nearly as hot as "super hots" Thai Hot Dragon is a variety you might like. It's very hot, not fruity, grows well and is quite prolific. Also I've heard the Charleston Hot is a very hot cayenne type but I've never tried one personally.
