Originally, cannabis ruderalis was considered a wild breed of cannabis. However, in recent years it has been brought indoors to influence new hybrid varieties. Cannabis ruderalis is a low-THC species of Cannabis which is native to Central and Eastern Europe and Russia. It is widely debated as to whether or not ruderalis is a sub-species of Cannabis Sativa. Many scholars accept Cannabis ruderalis as its own species due to its unique traits and phenotypes which distinguish it from Cannabis Indica and Cannabis sativa.
The term ruderalis stems from the root word ruderal. In the plant world, a ruderal species is one that grows in spite of its environment being inhabited by humans or being otherwise affected by naturally occurring disturbances to the area. Many believe ruderalis to be a descendant of indica genetics that adjusted to the harsh climates and the shorter growing seasons of the northern regions where it originates. Cannabis ruderalis is native to areas in Asia, Central/Eastern Europe, and specifically Russia, where botanists used the term “ruderalis” to classify the breeds of hemp plant that had escaped from human and cultivation, adapting to the extreme environments found in these climates.
