Narrow Leaflet Strain
Narrow leaflet strains are cannabis cultivars characterized by thin, elongated leaf blades compared to the broader leaflet morphology found in many modern hybrids. This trait is often associated with sativa-dominant genetics and equatorial landraces, where narrower leaves may have provided adaptive advantages in high-light environments. Breeders frequently observe this phenotype in heirloom lines from regions like Colombia, Thailand, and Mexico. Modern narrow-leaflet cultivars may carry these classical traits through intentional crosses or retain them from parent stock. The classification remains useful in breeding documentation for tracking morphological lineage and predicting growth patterns in hybrid development.

Narrow leaflet morphology is valuable to breeders working with sativa genetics or attempting to preserve landrace characteristics in stabilized lines. Growers and breeders use leaflet width as a phenotypic marker to identify and select for sativa-influenced traits during early vegetative assessment.
