Leaf Shape Classification
Leaf shape classification refers to the morphological categories used to describe cannabis plant foliage, ranging from narrow-leaflet sativas to broad-leaflet indicas and intermediate hybrids. Breeders and cultivators document leaf structure as a fundamental phenotypic marker, as leaf morphology correlates with broader growth patterns, environmental adaptation, and genetic lineage. Narrow-leaflet varieties are often associated with equatorial sativa genetics and tend toward extended flowering cycles, while broad-leaflet types frequently derive from indica ancestry adapted to shorter seasons. Intermediate leaf shapes commonly appear in modern hybrids. This classification system remains foundational in breeding records and plant identification, though individual plants within a strain may express phenotypic variation.

Breeders select for specific leaf morphologies to stabilize growth architecture, flowering time, and environmental tolerance. Leaf shape serves as a visual marker for tracking F1 hybrids, backcrosses, and phenotypic stability across generations.
