Marshmellow is a hybrid strain with unknown lineage, but most breeders agree, it's an OG Kush cross. Marshmellow is assumed to be a descendant of bubblegum, but its lineage remains shrouded in secrecy for now. Marshmellow is described as having a sweet, nutty aroma. Many users describe the flavor as sweet honey, and nutty earth. A relaxing body high puts the user in a tranquil state, eventually lulled into sleep, making this cultivar a great choice for muscle spasms or insomnia. Dominant Terpene : Caryophyllene.
