Thai is a name given to most landrace strains that are derived from an unspecified region in Thailand. Thought to be pure Sativa cultivars, Thai strains first gained fame as being the flower of choice for Thai sticks in the 1960s and 1970s due to the long, impressive size of its buds. Consumers would take the stickiest flowers, skewer them on stems, and tie them in place with string, usually referred to as “Rasta Hair.”

Many seed banks carry either pure Thai seeds or their own in-house phenotypes. Most contain a citrusy flavor, likely due to higher limonene content, while consumers favor the flower for its pleasing taste and reported energizing effects.
