Evergreen Phenotype

The Evergreen Phenotype describes a plant structure pattern where cannabis exhibits dense, persistent foliage throughout flowering—leaves remain abundant and green rather than fading or dropping significantly as blooming progresses. This trait is commonly associated with vigorous indica-influenced genetics or hybrids selected for structural robustness. Breeders working in this category often report that Evergreen Phenotypes require careful defoliation management to prevent mold risk in humid environments, as the dense canopy can trap moisture. The phenotype's heavy vegetative character during flower often correlates with longer finishing times compared to more typical flowering profiles. Understanding Evergreen expressions is relevant for indoor cultivation planning and humidity control protocols.

Breeders select for or against Evergreen traits depending on target environment—outdoor and greenhouse cultivators may favor the extended leaf protection, while indoor growers typically manage it through intentional pruning strategies. The trait influences light penetration and airflow patterns, making it a key consideration in phenotype selection for specific production systems.
