Flower Color

Flower color in cannabis refers to the visible pigmentation of buds and floral structures during bloom, determined by anthocyanins, carotenoids, and chlorophyll ratios. Colors range from green and white to purple, pink, and black, influenced by genetics, temperature stress during flowering, and nutrient profiles. Phenotypic expression varies significantly even within single cultivars, meaning identical genotypes can display different colors under different growing conditions. Lineage records frequently report color inheritance patterns, with some strain families reliably producing purple or red hues across generations. Breeders document flower color as a secondary trait for cultivar identification and market differentiation, though it remains genetically complex and environmentally plastic.

Breeders working in aesthetic cultivar development track color expression across parent plants and offspring to stabilize desirable hues. Consistent color phenotypes serve as visual markers for phytochemical profiles, though color alone does not determine cannabinoid or terpene content.
