Blacknana is an indica-dominant hybrid cannabis cultivar recognized for its dessert-fruit terpene profile, exceptionally high resin production, and distinct anthocyanin pigmentation. The name primarily identifies a cultivar developed in North America through a collaborative breeding project between Prima and Fresh Coast Seed Company, crossing Black Velvet with Bananaconda. In European seed markets, a distinct seed-line of the same name was created by Exotic Seed crossing Strawnana Juice #15 with Jelly Bananen. In licensed dispensaries, Blacknana is known for its conical, purple-speckled inflorescences, dark foliage, complex bouquet of ripe blackberries, bananas, and fuel, and a heavy, deeply relaxing physical finish.

Appearance
Blacknana exhibits exceptional bag appeal marked by contrasting coloration and calyx development. Buds mature into bright green, conical clusters patterned with deep purple marbling. The inflorescence architecture features elongated calyxes and mid-sized, chunky bract stacking rather than smooth, rounded nugs. The cultivar is particularly famous for its late-flowering foliage: fan leaves and surrounding sugar leaves frequently shift to jet-black tones under cooler night temperatures, displaying a distinct upward petiole curl. A heavy, uniform blanket of bulbous and capitate-stalked trichomes covers every bract, giving the dried flowers a glistening, silver-frosted sheen interspersed with curled, rusty orange pistils.
Aroma & Flavor
The olfactory profile of Blacknana balances dark fruit esters with confectionery sweetness and sharp hydrocarbons. Cured flowers release a bold, upfront bouquet of macerated blackberries and dark berries, layered over notes of ripe banana peel and confectionery sweetness. Breaking or grinding the flower uncovers pungent undertones of petroleum, wet loam, and peppery spice. Upon inhalation, the smoke or vapor carries rich fruit tones dominated by blackberry and creamy tropical banana. On the exhale, the profile finishes with smooth earthy spice, lingering sweetness, and a sharp touch of diesel.
Terpene Profile
Analytical certificates of analysis (COAs) for commercial Blacknana cuts, notably those distributed by licensed cultivators such as M.I. Jane in Michigan, demonstrate total terpene concentrations frequently measuring between 2.0% and 2.34%. The terpene configuration is anchored by beta-caryophyllene (frequently measuring 0.65% to 0.69%) and limonene (0.51% to 0.64%), which together drive its peppery kick and bright citrus-fruit lift. Secondary support is provided by beta-myrcene (0.26% to 0.30%), humulene (0.22% to 0.24%), pinene (0.18% to 0.21%), and trace levels of linalool and bisabolol, contributing floral nuance and rounded botanical complexity.
Potency & Cannabinoids
Prima documents total cannabinoid content for its Blacknana cut between 24% and 28%. State-licensed analytical batches show Delta-9-THC values under 1% and THCA concentrations reaching between 21.6% and 25.3%, translating to an active total THC baseline typically spanning 20% to 25.9%, with some pre-roll selections testing up to 28.36%. Minor cannabinoids contribute to the ensemble: tests consistently report CBGA in the 0.60% to 0.62% range, alongside minor traces of CBG (approximately 0.08%) and low CBD values (CBDA around 0.07%).
Effects
Note: Subjective effects are based on consumer accounts and dispensary documentation and are not medical claims. Individual experiences vary depending on dose and tolerance.
Mental Effects
Consumers commonly report an immediate wave of elevated mood and mild cerebral euphoria upon consumption. The initial head shift is described as clear, calming, and introspective, without racing thoughts or overstimulating energetic bursts. As the session progresses, mental chatter softens into a state of contented relaxation.
Body Effects
Blacknana’s physical onset develops shortly after the mental elevation, gradually releasing tension throughout the neck, shoulders, and spine. Consumers consistently report significant muscle relaxation, a warm physical heaviness, and mild couch-lock at higher doses. Because of its physically unspooling nature, Blacknana is widely favored for evening unwinding, post-work recovery, and nighttime consumption.
Cultivation Characteristics
Blacknana grows with a stocky central structure and tight internodal spacing during vegetative development, but demonstrates significant vertical stretch once transitioned to an inductive 12/12 photoperiod. Indoor flowering completes in approximately 58 to 63 days for the Prima cut, while European seed selections recommend 9 to 10 weeks (63 to 70 days). Prima notes that indoor canopies generate above-average yields, often cited around 2.5 pounds per grow light under optimized commercial environments. Exotic Seed reports European indoor yields between 450 and 600 g/m². The cultivar performs exceptionally well in northern outdoor climates, such as Michigan, where ambient autumn temperature drops trigger deep anthocyanin expression, turning leaves dark purple to jet-black before an outdoor harvest in mid to late October.
Resin & Extraction Characteristics
A primary objective in breeding the Black Velvet × Bananaconda cross was hash yield. Blacknana inherits dense trichome coverage and brittle gland heads from its parental lineage. The Black Velvet parent (a selected Dante’s Inferno cut) is celebrated for fresh frozen water hash washing returns exceeding 5%. Blacknana replicates this performance, producing high returns of solventless bubble hash and live rosin with an aromatic wash rich in fruit esters, dark berry sweetness, and gassy volatiles.
Scientific & Botanical Overview
Botanically, Blacknana exhibits strong morphological indicators of its Afghanica and polyhybrid heritage. The high accumulation of anthocyanins in the floral bracts and petioles is governed by temperature-sensitive flavonoids that manifest when night temperatures drop below 18°C (64°F). The calyxes elongate naturally during mid-to-late anthesis, generating conical, clustered racemes rather than globular clusters. Its glandular trichomes are primarily capitate-stalked with full heads that exhibit high fragility at freezing temperatures, which explains the strain’s utility in mechanical trichome separation methods.
Lineage & Related Strains
The predominant North American lineage consists of:
- Black Velvet: A prized cut of Dante’s Inferno (Mile High Dave × Oreoz), selected by Clearwater Genetics and Tiki Madman, renowned for reaching ~29% THC, dark black foliage, and >5% solventless hash returns.
- Bananaconda: A Snake Eyes × Modified Banana hybrid bred by Honey Sticks Genetics, passing down robust confectionery banana aromas, resin thickness, and sedative indica traits.
Growers should distinguish Blacknana from Black Banana (Banana Fire Cookies × Blackberry Kush, bred by Relentless Genetics), which shares overlapping flavor profiles but has a distinct pedigree. In Europe, Exotic Seed’s Blacknana traces to Strawnana Juice #15 × Jelly Bananen, offering a strawberry-banana dessert profile rather than the blackberry-gas framework of the Michigan collaborative cut.
Sources & Data Notes
Data compiled for this profile originates from original breeder documentation by Prima Clones, Fresh Coast Seed Company lineage announcements, Exotic Seed strain technical sheets, and batch certificates of analysis from licensed cannabis testing labs in Michigan (including M.I. Jane and Galaxy Labs releases). Because two independent cultivars carry the Blacknana trade name, cultivators and consumers should verify breeder documentation to confirm whether a batch derives from the Michigan Black Velvet × Bananaconda cross or the European Strawnana Juice × Jelly Bananen cross.
Blacknana Summary
Blacknana is a resin-dense, indica-leaning cultivar defined by conical green-and-purple buds, jet-black fan leaves, and a terpene profile blending ripe blackberry, creamy banana, and pungent gas. Developed by Prima and Fresh Coast Seed Company (with an unrelated hybrid bred by Exotic Seed), it delivers 20% to 28% THC potencies, an indoor flowering window of 58 to 63 days, and top-tier suitability for solventless hash production and evening physical relaxation.
