Banana Kush is a cultivar with at least two origin stories. The breeders at Cali Kush claim their Banana Kush is a cross between the widely-known OG Kush and a male Banana. This genetic combination formed a cultivar with a creamy banana flavor and the sedative effects OG Kush is known for. Crockett Family Farms tells another tale. The breeders there claim that Banana Kush descended from a particular phenotype of OG Kush named Ghost OG, which was crossed with a Skunk x Haze hybrid. Ghost OG reportedly had boasted stable genetics for nearly nine years at the time of breeding, while Skunk x Haze has enjoyed a stellar reputation since the 1970s. Banana Kush was so named simply for its mild banana aroma. Regardless of its origin, Banana Kush certainly carries California OG Kush genetics and features banana flavors and scents.
