All of today’s strains inevitably derive from pure, ancient cannabis plants found throughout the world and referred to as “landraces.” Landraces occur naturally and adapt to a particular region, over a long period of time, without any external influences.
Marijuana landrace strains are ones that are indigenous to a specific location. That means that they are naturally occurring in that area, and they have never been cross-bred with any other strain of marijuana. They are generally a very old strain, having been inbred throughout history over and over again. They are pure, and each plant is highly similar to each other. Generally speaking, a landrace will either be completely indica or completely sativa.
Landrace strains used to be the most sought-after strains in the world, offering a vast array of different strain options to people who traveled the world in search of new strains of marijuana.
