The calyx is the first part of a flower that forms. It is made up of a collection of small leaves that form in a spiral near where the flower meets the stem, and is made up of sepals, which are tiny leaves that protect the flower at its base.
The calyx is part of the bud, which may, in turn, be a part of the much larger cola. The calyx holds many of the most important plant parts, including:
- Pistils: The reproductive organs of the plant, including the long hairs called stigmas
- Trichomes: The resin glands that provide cannabinoids, including psychoactive THC
