Black Rose
Black Russian × Rosetta Stone × Shishkaberry × Nebula
Black Rose is a visually striking cannabis cultivar recognized for its deep purple to nearly black flowers and dense resin production. It is often described as a small family of related strains rather than a single, uniform cut, leading to some variability in reported characteristics. Despite this, it is consistently noted for its appealing appearance and potent, evening-leaning effects.
Appearance
Black Rose is characterized by its dark anthocyanin expression, often resulting in inky purple to near-black flowers, particularly when exposed to cooler temperatures late in the flowering cycle. The strain typically produces dense, spear-shaped colas with a calyx-forward structure. Its buds are known for heavy trichome coverage, giving them a frosty appearance, and the sugar leaves may exhibit burgundy streaks or purple mottling.
Aroma & Flavor
The aroma of Black Rose is a complex blend, often described as floral and berry-like, evoking its namesake. Initial notes commonly include sweet grape and ripe berry, layered over a hashy, spicy foundation. When ground, a rosy, tea-like nuance emerges, sometimes accompanied by subtle hints of lavender or lilac. The flavor profile often mirrors the aroma, presenting a sweet, fruity, and floral experience with a lingering peppery or spicy finish.
Effects
Black Rose is generally considered an evening-leaning hybrid, providing relaxing effects that are potent and suitable for unwinding. While specific effects can vary due to its nature as a cultivar family, users often report a calming sensation that promotes relaxation. The strain is known for its above-average bag appeal and consistent trichome production.
Terpenes & Cannabinoids
Black Rose typically exhibits medium to high THC levels, ranging from 15-25%, with minimal CBD content (<1%). Prominent terpenes often include Myrcene, Limonene, Caryophyllene, Linalool, and Humulene, contributing to its distinct aroma and potential effects. Myrcene-dominant phenotypes are associated with more sedation, while Limonene-influenced varieties may offer a slightly brighter experience.
Origins & Lineage
The origins of Black Rose trace back to underground breeders in the mid-to-late 2000s who aimed to enhance purple coloration without compromising potency. It is understood as a family of closely related cultivars, with multiple credible versions in circulation. Common genetic influences cited include Black Russian, known for its resin and dark colors, potentially crossed with vigorous, terpene-rich partners. Some lines may also incorporate genetics from Rosetta Stone, Shishkaberry, or Nebula, contributing to its fruity and floral characteristics.
Growing
Black Rose is typically a medium-statured plant with robust branching and a calyx-forward structure. Indoor flowering usually concludes in 8 to 9 weeks, with yields reported between 450-550 grams per square meter under optimized LED lighting. Outdoor plants can grow over 2 meters tall and are ready for harvest in early to mid-October in temperate climates. Achieving its signature dark coloration often requires cooler night temperatures in the late flowering stage.
