Purple Phenotype Descriptors
Purple phenotype descriptors refer to visual markers—anthocyanin pigmentation in flowers, leaves, and stems—observed in cannabis plants under specific environmental conditions, particularly cooler temperatures during flowering. These traits are inherited polygenetically and influenced by both genotype and phenotypic expression. Breeders distinguish between stabilized purple lines (where pigmentation appears consistently) and environmental responders (where color emerges only under stress). Documentation of purple phenotypes helps maintain breeding records and supports selective work toward colorful cultivars. The trait exists across numerous genetic backgrounds and is not linked to cannabinoid or terpene profiles.

Breeders working with purple phenotypes track anthocyanin expression as a visual marker for line stability and environmental responsiveness. Selecting parent plants that reliably produce purple coloration under controlled conditions allows breeders to develop more predictable cultivars for commercial and research contexts.
