>>1084148A little warning though, my potted Jalapenos don't do that well compared to other C.Annuums in pots or their brethren in the bed, so use a pot as big as possible, like the one with your Bulk Jolokia for maximum growth and yield.
If you want some pepper seeds leave some throwaway email here to exchange info and I'll send you some. Already mentioned some variants, but I have plenty of tested seeds from a few more as well.
The four other peppers you have a C.Annuums, the Bulk Jolokia is, as
>>1084399already said, an oddity between C.Chinense and C.Frutescens. Check pic related about crossing probability. It's also worth noting it does not exactly work like that, the 0.5m will do squat. Peppers are self-pollinating, but there are still insects and such a short distance can easily be bridged by a gust of wind.
And of all five common cultivars, C.Chinense and C.Annuum are the ones that cross the easiest with each other. But you can never be sure and most crossing isn*t that radical.

Don't worry too much about crossing though. It's not that important unless you sell seeds professionally.
