Sirius Black is an indica-dominant hybrid whose exact parentage remains closely guarded by its breeders. Origin tracing places its development in the early 1980s with the Oregon Breeders Group in Portland as part of the Sirius Black Project, an effort to sculpt the perfect dark purple bud. The outcome is a striking phenotype whose lineage is a well-kept secret, celebrated for its deep, regal coloration and potent profile.
Its flowers are dense and spade shaped, wrapped in rich purple hues and threaded with fiery orange hairs, the buds gleaming under a coat of lavender-tinted crystal trichomes. The flavor rides a sweet grape and berry bouquet with a tart yet smooth exhale that lingers on the palate. When burned, the aroma shifts toward sweet earthy berries infused with musk and a tang of citrus, inviting a long, fragrant exhale.
The initial effects arrive as a cerebral lift, infusing the user with hazy creativity and a buoyant sense of euphoria. As the high deepens, a substantial body buzz settles in, bringing deep relaxation and a sedating calm that can ease into sleep for many users. With an average THC around 19 percent, Sirius Black sits on a roughly 70 percent indica to 30 percent sativa balance, reinforcing its heavy, sleep-friendly profile and making it a popular choice for relief from chronic pain, fatigue, inflammation, insomnia, and depression.
