Flower Architecture

Flower architecture refers to the structural and morphological organization of cannabis inflorescences, including bract density, calyx-to-leaf ratio, flower compactness, and internal pistil arrangement. Breeders classify plants along a spectrum from airy, open-structured flowers to dense, tightly-packed formations. These traits are heritable and influenced by both genetics and environmental conditions during flowering. Documentation of flower architecture helps distinguish between strain families and serves as a baseline phenotype descriptor in breeding programs. Understanding these structural patterns is essential for cultivation planning, as architecture affects airflow, moisture management, and harvest efficiency.

Breeders select for specific flower architectures to optimize yield density, disease resistance, and processing suitability. Dense-structured lines are often crossed with airy phenotypes to achieve intermediate forms suited to particular growing environments or end-use applications.
