ihuntbucks,
Check out the link that Greg put up there, it has a small article about the bhut jolokia. Supposedly, they are about 4 times hotter than the Red Savina, which was the leader until this one showed up, and almost 10 times hotter than a Habanero. Whether that is all hype, I dont know yet. To my knowledge, it is not a hybrid, but native to India.
If you remind me later in the year, after I get a couple of peppers, I can mail you a couple of seeds for you to try for yourself next year.
I don't know how wide spread they are in the nurseries. I am sure the seeds had to be special ordered early on and started by the nursery back in Feb. I also don't know if any of the Seed magazines had any for sale this year either.
