Wide Leaflets

Wide Leaflet morphology describes cannabis plants with notably broader, shorter leaf blades relative to length-to-width ratios typical of narrow-leaflet cultivars. This trait appears across diverse strain families and is influenced by both genetic background and environmental factors during growth. Breeders often note wide leaflets in indica-dominant and hybrid populations, though the expression varies significantly within and across lineages. The morphological difference affects light interception, transpiration rates, and overall plant architecture. Wide leaflet plants are sometimes associated with Central Asian and Afghan cannabis populations in lineage records, though selective breeding has distributed this trait globally across modern cultivars.

Breeders working with wide-leaflet traits consider implications for canopy structure, humidity management in dense foliage, and phenotypic consistency within breeding lines. Selection for or against wide leaflets depends on cultivation environment and intended plant structure—growers in high-humidity settings may breed away from this trait, while others incorporate it for specific architectural go
