Burgundy Pigmentation

Burgundy pigmentation refers to deep red, maroon, and wine-colored anthocyanin expression in cannabis plant tissues—most visibly in flowers, leaves, and occasionally stems. This trait develops under specific environmental conditions, particularly cool temperatures and light exposure, though genetic predisposition determines the intensity and range of color expression. Anthocyanins are water-soluble pigments also responsible for red and purple hues in many plants; in cannabis, they accumulate alongside chlorophyll as temperatures drop. Burgundy pigmentation is distinct from purple or violet phenotypes, typically exhibiting deeper, more brownish-red tones. Documentation of this trait appears frequently in breeding records for cultivars derived from Afghan, Hindu Kush, and certain North American heritage lines. The expression is non-essential for plant viability and does not directly influe

Breeders working toward burgundy phenotypes typically select parent plants expressing strong anthocyanin production, then expose seedlings to cooler nighttime temperatures during late flower to encourage color development. This trait is often combined with other visual markers in stabilization programs targeting aesthetic consistency across seed batches.
