Leaf Shape
Leaf shape is a fundamental morphological trait in cannabis that varies significantly across cultivars and landraces. Variations range from narrow, sativa-like leaflets to broad, indica-typical foliage, with many modern hybrids displaying intermediate phenotypes. Leaf morphology is influenced by both genetic ancestry and environmental conditions during vegetative growth, making it a useful but not definitive classification marker. Breeders and cultivators track leaf shape as part of phenotype documentation, though it correlates imperfectly with cannabinoid or terpene profiles. Leaf shape also affects light penetration, airflow, and canopy management decisions in cultivation.

Breeders document leaf shape as a visual phenotypic marker when stabilizing lines and recording F1 hybrid characteristics. Leaf morphology can influence cultivation strategy and is often cross-referenced with growth rate and branching patterns when selecting parent material.
