Terpenes are fragrant oils that give cannabis its aromatic diversity. They’re what give Blueberry its signature berry smell, Sour Diesel its funky fuel flavor, and Lavender its sweet floral aroma. These oils are secreted in the flower’s sticky resin glands, the same ones that produce THC, CBD, and other cannabinoids.
Out from the calyxes peek tiny red-orange hairs; these vibrant strands are called pistils, and they serve to collect pollen from males. They play an important role in reproduction, but pistils bring very little to the flower’s potency and taste.
Despite their minute size, it’s hard to miss the blanket of crystal resin on a cannabis bud. This resin (or “kief” when dry) is secreted through translucent, mushroom-shaped glands on the leaves, stems, and calyxes.
