Citrus

Citrus aroma in cannabis refers to volatile compounds that evoke lemon, lime, orange, and grapefruit notes. These scents are commonly associated with limonene and other terpenes like pinene and myrcene, which occur naturally across many plant lineages. Citrus-forward profiles appear frequently in modern breeding work, particularly in sativa-dominant and hybrid crosses. Breeders often select for citrus character through phenotype hunting and backcrossing to stabilize terpene expression. Documentation of citrus aromatics in cannabis dates back to vintage landraces and heirloom strains, though contemporary cultivars show more pronounced and consistent profiles.

Citrus aroma is a selectable trait used in breeding programs to create distinctive sensory markers and market differentiation. Growers and breeders monitor terpene output under different environmental conditions to predict and enhance citrus expression in offspring.
