Appearance

Skullcap flowers are typically dense, often forming golf-ball or spear-shaped colas with tightly stacked calyxes. The bract-to-leaf ratio is favorable, and well-grown specimens are covered in trichomes. Coloration is generally green, with pistils ranging from tangerine to rust. Some phenotypes may develop purple streaks in cooler temperatures, and swollen calyxes can give the buds a quilted appearance.

Aroma and Flavor

The aroma of Skullcap is characterized by fuel-like notes, pine, and lemon, underpinned by an earthy, kushy base. Secondary scents can include white pepper and herbal notes. Upon grinding, the aroma intensifies, revealing metallic diesel, sour citrus, and peppery notes. Flavors on the inhale include citrus and diesel with pine, followed by earthy and slightly bitter kush notes, and a peppery finish. The exhale often features fuel, dry herbs, and a subtle woody sweetness.

Origins and Lineage

Skullcap is a hybrid strain that emerged on West Coast and Mountain West dispensary menus in the mid-to-late 2010s. Its name is inspired by the calming herbal remedy skullcap. While exact parentage varies by breeder, most versions are believed to have an OG/Kush-derived lineage combined with a sour or chem-influenced strain. This combination contributes to its characteristic gassy, lemon-pine, and earthy notes.

Growing
