Dutch breeder Royal Queen Seeds created the auto-flowering Royal Haze, not to be confused with Royale Haze, as a combination of Amnesia Haze and Kush with some ruderalis thrown in. Royal Queen set out to take the very popular sativa Haze variant and shorten its growing cycle by introducing an indica while using a ruderalis for its autoflowering properties. 

The top reported aromas of the Royal Haze strain are lemon, spice, and skunk. It is said to taste of cedar, pine, and citrus.
