Female Flowers

Female flowers are the reproductive structures that develop on female cannabis plants, characterized by pistillate florets with paired, hair-like stigmas designed to capture pollen. These flowers are the primary target of cultivation in most legal markets, as they accumulate cannabinoids and terpenes in specialized glandular trichomes covering the bracts and calyxes. Female flower development is triggered by photoperiod changes in photoperiodic varieties, or occurs automatically in autoflowering genetics. Breeders and cultivators selectively propagate female plants through cloning or feminized seed production to ensure consistent, high-yielding crops. Understanding female flower morphology—including calyx density, stigma coloration, and resin production timing—remains central to strain development and cultivation optimization.

Breeders assess female flower traits like calyx-to-leaf ratio, trichome density, and flowering speed when selecting parent plants for new cultivars. Female flower phenotypes vary significantly across genetic backgrounds, making careful selection essential for predictable crop characteristics and cannabinoid/terpene profiles.
