Narrow Leaf Plant Nlp

Narrow Leaf Plant (NLP) is a morphological classification rather than a terpene profile, referring to cannabis plants expressing thin, elongated leaflets—a trait commonly associated with sativa-dominant genetics and certain equatorial landraces. This phenotype is frequently observed in breeding lines with reported Southeast Asian or African ancestry. NLP plants typically exhibit longer internodal spacing and extended flowering periods compared to broad-leaf phenotypes. Breeders and cultivators distinguish NLP expressions because leaf morphology can influence light penetration, airflow, and cultivation requirements. Historical cannabis taxonomy often used leaf width as a primary classification marker, though modern genetic analysis shows this trait can appear across diverse genetic backgrounds.

Breeders working with NLP genetics often select for this trait when targeting sativa-like growth structures or tropical adaptation characteristics. Maintaining NLP lineages requires deliberate phenotype selection across generations, as leaf morphology can segregate in hybrid crosses.
