There is absolutely no question that there are two very distinct varieties of Red Congo. It is not even an argument but rather a documented fact. I have submitted a photo of the African landrace variety.
To be fair, there should be two completely unique categories for this name. You can't even put them in the same group, as they are so unique and unalike.
Developed and grown to perfection this fair red lady was recently produced by temple of calyx, a Canadian consortium of master growers. As you can see, it clearly contains zero indica and is as true a sativa as it gets. The potency soars in this one, promising close to 30% thc.
The scent, while deceptively familiar, is a true delicacy for the experienced connoisseur. The end flav is actually completely unlike the scent she gives off. This is no Mexican red hair, nor is it a bred result to achieve a specific trait; but rather an exotic sativa the likes of which many will never know as red Congo, as the more common variety can hardly be cross referenced with the African landrace for any other reason than perhaps fragrance.
The good news is, this variety being so whispy and red, you would have a very hard time confusing one with the other. What I have noticed is, that most strains our southern USA friends have often appear to be the hybrid, sadly one of the key problems with a name is that it rarely tells us much about the strains true history and actual status in the world today.
The African variety could easily be dismissed as a very average, typical mild sativa from yesteryear, but in fact, it is a gem that without knowing someone who's actually got the real deal, is often very rare to find. It reminds me of the memorable, blow your socks off sativas we found back in the early 80s when premium landrace still dominated the high end market.
Look for this one at your favorite Canadian supplier. Most recently spotted in Van and Ontario, I was lucky enough to get some and cherish every puff.
