Geraniol Terpene Expression

Geraniol is a monoterpene commonly expressed in cannabis cultivars, contributing floral and rose-like aromatic notes. This compound is frequently detected in strains with complex terpene profiles, though geraniol concentration varies significantly across lineages and cultivation conditions. Geraniol is also found in geranium flowers, rose oil, and other plant families, making it a recognizable aromatic compound in botanical contexts. In cannabis breeding, geraniol expression is often tracked as part of secondary terpene profiling, particularly in cultivars developed from parent lines known for floral characteristics. The presence of geraniol does not determine cannabinoid profile or potency—it is one of many volatile compounds that contribute to strain aroma complexity.

Breeders working with terpene-focused selections sometimes track geraniol as a marker for floral or garden-like aromatic phenotypes. Preserving geraniol-forward expressions requires consistent phenotype documentation across generations, as terpene volatility and environmental influence can shift expression levels.
