Late Flowering Phenotypes

Late flowering phenotypes are cannabis plants exhibiting extended vegetative or flowering cycles compared to standard varieties, often requiring 10–14+ weeks to mature. These traits typically emerge from landrace genetics adapted to extended growing seasons or from deliberate breeding selections prioritizing yield development and resin maturation. Breeders working with late-flowering material often document longer internodal spacing, sustained branch development, and extended trichome maturation windows. While flowering duration varies by environment and specific lineage, late phenotypes are frequently observed in Indica-dominant crosses, Afghan-influenced genetics, and some South Asian origin strains. Understanding flowering timeline is essential for cultivation planning, seed selection, and breeding program design.

Breeders select for late-flowering traits when targeting larger final plant structure, extended resin accumulation periods, or adaptation to specific photoperiod conditions. These phenotypes are commonly crossed with faster-maturing lines to create intermediate-duration hybrids suitable for diverse grow environments.
