Kush refers to a group of cultivars of Cannabis sativa subsp. indica, that originated in the Hindu Kush region. It has been heavily domesticated and interbred since its discovery by Western society, thus none can be sure of its exact ancestry. Due to its indica genetics, kush grows into a short, thick plant, with one main cola (as opposed to C. sativa subsp. sativa strains, which usually produce multiple stalks).
