Chlorophyll Expression
Chlorophyll expression refers to the visible pigmentation patterns in cannabis foliage, ranging from standard green to purple, red, or near-black coloration. These phenotypic variations arise from genetic factors—particularly anthocyanin and carotenoid production—interacting with environmental conditions like temperature, light spectrum, and nutrient availability during growth. Chlorophyll expression is a cosmetic trait with no direct relationship to cannabinoid or terpene content, though breeders often document it as a marker for phenotypic consistency. Understanding chlorophyll variants helps cultivators and seed developers predict plant appearance and identify stable genetic lines across generations.

Breeders working in this category track chlorophyll variants as visual phenotype markers to stabilize cultivar identity and population genetics. Purple, red, and variegated expressions are often selected for market differentiation, though breeding focus remains on underlying genetic stability rather than pigment alone.
