The pepper you are seeking would be any one of the following :
Bhut Jolokia (aka ghost chile)
Trinidad Scorpion
Seven Pot
Naga Morich

Those pepper's are extremely hot and not a pepper to play around with. They have an extremely long growing season. I live in Texas and my bhut jolokia's took almost 7 months from when they germinated to bloom. This was during a normal growth pattern. I currently have 3 plants. I had some blooms fall off during our heat wave in Texas and hope to have some blooms by mid-late September.

Good luck on searching out seed for this, and if you are growing from seed - be extremely patient. I'd recommend requesting a pod or two from someone rather than seeds as seeds would take way too long to grow peppers - unless you are willing to wait until next year for peppers to grow out.

I have some Bhut Jolokia Peppers. I did not bag blossoms, so if you
grow out seeds it could be crossed or not. I also have Fatalli pepper
and Jamaican Hot chocolate Habanero.

I have red Bhut's ready to go. I also have two rare habanero's( the white and spicy mustard) both are pure fire and torture.
