Flower Site Distribution

Flower site distribution describes the spatial pattern and density at which flower clusters develop along a cannabis plant's stem during blooming. Plants may exhibit concentrated flowering at branch terminals (apical dominance), distributed flowering along internodal segments, or sparse lateral flowering depending on genetics and structure. This trait is primarily determined by growth morphology—tall, branchy cultivars typically show distributed patterns, while compact or single-stem plants concentrate flowers at fewer sites. Understanding flower site distribution is relevant to yield prediction and canopy management, as it affects overall flower production density and harvest efficiency. Breeders working in commercial breeding track this characteristic as it correlates with plant architecture and cultivation outcomes.

Breeders select for flower site distribution patterns to optimize yield density and adapt plants to specific cultivation environments. Distributed flowering supports higher total flower counts in larger canopies, while concentrated flowering suits compact, high-density growing systems.
