Broad Leaf Vs Narrow Leaf
Broad leaf and narrow leaf designations describe the width and shape of cannabis leaflets, a trait controlled by multiple genetic factors. Broad leaf plants typically display wider leaflets with shorter internodal distances, while narrow leaf variants show elongated, slender leaflets and often taller plant architecture. These morphological differences have been observed across many geographic origins and modern cultivars, suggesting polygenic inheritance. Breeders working in this category have historically used leaf shape as a marker for breeding goals, though the trait remains independent of cannabinoid or terpene profiles. Both phenotypes appear in established heirloom lineages and contemporary seed collections worldwide.

Leaf morphology influences light capture efficiency, airflow, and disease susceptibility during cultivation—factors breeders consider when adapting strains to different growing environments. Selection for broad or narrow leaf traits has been used alongside other agronomic markers to develop regionally adapted cultivars.
