Lavender Phenotypes

Lavender phenotypes represent a distinct visual and structural classification within cannabis breeding, characterized by purple, violet, or blue-tinted foliage and flowers—typically triggered by anthocyanin pigment expression under specific temperature or genetic conditions. This classification emerged prominently in modern breeding through crosses involving parent strains with documented purple traits, though phenotypic expression varies significantly based on growing environment, particularly cooler night temperatures during flowering. Lineage records frequently report lavender phenotypes in families descended from strains like Purple Urkle, Granddaddy Purple, and various Afghani-influenced cultivars. The trait is not tied to a single genetic locus; rather, multiple alleles and environmental factors interact to produce the characteristic coloration. Breeders working in this category of

Breeders use lavender phenotypes as a visual marker for lineage verification and as a breeding target for cultivar differentiation in competitive markets. Stabilizing purple expression across multiple generations requires selective crossing of purple-expressing parents and environmental trial data to predict phenotype reliability.
