Dark Green Phenotypes

Dark green phenotypes represent cannabis plants with notably elevated chlorophyll density and reduced anthocyanin expression, resulting in deep forest-to-black-green foliage throughout the growth cycle. These phenotypes appear across multiple strain families and are influenced by both genetic predisposition and environmental factors including light spectrum, temperature, and nutrient availability. Breeders have documented dark green expression in lineages such as Pakistani Hash Plant, Black Domina, and various Afghani-derived cultivars, where the trait often correlates with dense trichome development and compact plant architecture. The trait is considered relatively stable when selected across generations, though expression can intensify or mute depending on cultivation conditions. Dark green phenotypes are commonly associated with plants expressing recessive chlorophyll genes and are fr

Breeders working in hash-plant and landrace-preservation categories often select for dark green phenotypes as a visual marker for desired resin profile and plant vigor. The trait's stability makes it useful for establishing phenotypic consistency across seed runs and for maintaining distinctive visual identity in commercial breeding lines.
