Yes, this stuff is all quite confusing and would take a fair amount of time/writing to lay out. There is in fact a regular Moruga Red and Moruga Yellow, which seem to be a habanero line (large pods / nice flavor). These were sent at the same time the 7 Pot and Scorpions were. I have every original seed packet ever sent so no doubt on any of the lineage in my eyes! Then there is the 'original' Trinidad Scorpion Moruga Blend Red, which ironically came from an old friend of mine in TOBAGO. I will not say anyone ever claimed it to be a hybrid between a Scorpion and 7 Pot because they didn't. That was taken as gospel over the years, but not confirmed by the grower. It certainly is a possibility though given the attributes. I am 99.9% sure this variety was obtained from CARDI test fields (in other words, I got damn lucky to get it).
I know I had real CARDI material because my friend knew very well what the real Trinidad Scorpion was and my stuff matches CARDI's photo selections. I kept the TSMB label as that is exactly how this variety came to me from Tobago. I was told this was a crazy hot, super bumpy scary looking pepper.
The 7 Pot Jonah and Trinidad Scorpion Butch T are different animals, yet pretty stable ones. If I had to make a statement, I'd say the TSMB Red and Sara's original 7 Pot Red from Trinidad are very close, but the latter will spin off more pod shapes than the TSMB. Texture and heat are extremely similar and many times if a group of pods were laid across a table, many would struggle to find the differences.
I could go on and on....does Trinidad Scorpion Moruga Blend YELLOW truly exist? lol......... Well, a 7 Pot Yellow was sent in '08. Douglah sent in '08. I think the TSMB yellow was simply a selection of the 7 Pot Yellow and named differently. This selection process occurs often though so it doesn't necessarily mean it was done to deceive anyone. CARDI may grow a lot of stuff and work on stabilizing landraces, but I doubt they are in tune with every hybrid like some 'addicts' of super hots are.
Obviously, many variations exist such as the 7 Pot Long LG I grew and sent around years back. I always found that one fascinating as it seemed to have some Naga traits, but not a true Naga.
With all the new crosses being put out at an astounding rate, it may be easy to forget what the originals ever were.
