Leaf Type Narrow

Narrow leaf type refers to cannabis plants exhibiting thinner, more elongated leaflets compared to broad-leafed varieties. This classification often correlates with sativa-dominant genetics and plants originating from equatorial or subtropical regions. Narrow-leafed plants typically display longer internodal spacing and more delicate foliage structure. The trait has been documented across various breeding lineages, particularly those with Sativa ancestry or Southeast Asian heritage. Growers and breeders frequently observe narrow leaves alongside specific growth patterns, though environmental factors and individual plant expression can influence leaflet width.

Breeders working with narrow-leafed genetics often select for this trait when developing sativa-leaning hybrids or when seeking to preserve regional landrace characteristics. The narrow leaf phenotype is commonly used as a visual marker in breeding programs to identify and maintain specific genetic backgrounds across generations.
