The Blueberry strain UK collectors ask about is DJ Short’s Blueberry, an indica-dominant line from the late 1970s built on Thai, Purple Thai and Afghani landraces. It won the 2000 High Times Cannabis Cup and is known for its fresh blueberry aroma, led by the terpene myrcene.
Few names in cannabis genetics carry as much history as Blueberry. This guide looks at where the line comes from, what the published data says about its aroma and terpenes, how Blueberry-descended seeds are sold today, and what to check before adding one to a collection.
The Genetics Behind Blueberry
Blueberry was developed by the American breeder DJ Short. His own seed company, DJ Short Seeds, dates the line back to the late 1970s and describes it as roughly 80% indica and 20% sativa. Strain databases trace it to exotic landrace genetics: Leafly lists the parents as Purple Thai and Thai, while other references add an Afghani indica to the mix. That combination gave Blueberry its signature pairing of deep colour, fruity aroma and indica-leaning structure.
Because Blueberry has been used by so many breeders over the decades, the name now appears on a wide range of seed lines. Anyone researching the strain should look for listings that trace their stock back to the DJ Short lineage, rather than a loosely related hybrid using the name purely for marketing. Our guide to why the same strain name can hide different genetics explains how that happens.

Aroma and Flavour: Blueberry’s Signature Trait
Aroma is where Blueberry truly separates itself from other classic strains. The scent is sweet, fruity and unmistakably reminiscent of fresh blueberries, with a subtle earthy base underneath that keeps the profile from feeling artificial or one-dimensional.
This profile comes down to a specific set of terpenes, as reported by Leafly’s Blueberry strain data:
- Myrcene, the dominant terpene, adds a musky, fruity sweetness and is largely responsible for the strain’s signature scent.
- Caryophyllene contributes a peppery, earthy depth that balances out the sweetness.
- Pinene gives a faint, fresh pine sharpness beneath the fruit-forward top notes.
Few varieties balance sweetness and depth this well, and even fewer have held onto that balance across so many decades of reproduction. That is why Blueberry remains one of the most requested aroma profiles among collectors, and why so many newer hybrids try to recreate a similar scent without quite matching the original.
Why It’s So Popular Among UK Collectors
Blueberry’s popularity is not a passing trend. The line has been in circulation for more than four decades and continues to serve as a genetic foundation for many modern hybrids, which says a great deal about how well it has held up over time.
A few reasons it remains in such high demand:
- Award history, most notably first place at the 2000 High Times Cannabis Cup.
- A recognisable aroma that collectors can compare across different Blueberry-descended lines.
- Strong genetic influence, with the Blueberry name appearing in the lineage of many later crosses.
- Wide appeal, suiting both experienced collectors chasing heritage genetics and newer enthusiasts drawn in by the name.

Blueberry-Descended Seeds at Canna Genetics
Canna Genetics sells feminised and autoflowering seeds only, in 1-seed and 3-seed collectible packs. Feminised seeds are bred to carry female-only genetics, while autoflowering lines include ruderalis genetics and can carry a slightly different terpene balance from the original.
Our Blueberry line is Blueberry OG seeds, a feminised cross of DJ Short’s Blueberry with OG Kush. If you searched for Blueberry OG, that product page has its own lineage and reported data. It keeps Blueberry’s berry sweetness and adds the citrus, pine and fuel notes of the OG side. Other indica-leaning collectibles are in our indica seeds collection.
Cannabis Seeds for Sale in the UK: What to Look For
Not every listing offering cannabis seeds for sale in the UK provides the same transparency. Some sellers rely on the Blueberry name without confirming any real genetic background. Before adding a Blueberry line to a collection, check for:
- Clear breeder information and a stated lineage, ideally traceable back to the DJ Short genetics.
- THC and terpene figures given as ranges and labelled as reported breeder or seed-bank data, rather than single, suspiciously precise numbers.
- A clear seed type, so you know whether a listing is feminised or autoflowering.
- Honest legal wording that sells seeds as collectible souvenirs to adults.
Our full checklist, cannabis seeds for sale in the UK: what to look for, covers this in more detail.
Are Blueberry Seeds Legal in the UK?
Yes, it is legal for adults to buy, sell and own ungerminated cannabis seeds in the UK, because the seeds themselves contain no controlled cannabinoids. Germinating or cultivating them without a Home Office licence is an offence under the Misuse of Drugs Act 1971. Our explainer, are cannabis seeds legal in the UK?, sets out the detail.
Frequently Asked Questions
Blueberry’s reported terpene profile is led by myrcene, backed by caryophyllene and pinene, which gives it a fruity aroma with an earthy, peppery base rather than a purely sweet one. Its indica-dominant heritage, reported at about 80% indica, also sets it apart from sativa-leaning fruity lines.
Blueberry was bred by the American breeder DJ Short, who began working on the line in the late 1970s using Thai, Purple Thai and Afghani landrace genetics. It went on to win the 2000 High Times Cannabis Cup.
Check for a stated lineage that traces back to DJ Short’s Blueberry rather than a loosely related hybrid. A reputable seller will name the cross, label figures as reported breeder data and explain the breeding history behind a Blueberry line.
Reported figures put Blueberry at roughly 15–22% THC, with Leafly giving an average of about 17%. Figures vary by cross, breeder and phenotype and describe the genetics only. Ungerminated seeds contain no THC.
Leafly’s reported data lists myrcene as Blueberry’s dominant terpene, with caryophyllene and pinene behind it. Myrcene gives the musky, fruity sweetness, caryophyllene a peppery depth and pinene a light pine note. These are reported strain-database figures and vary between cuts and sources.
Yes. Adults aged 18 and over can legally buy and own cannabis seeds in the UK because ungerminated seeds contain no controlled substances. Germinating or cultivating them without a Home Office licence is illegal, so Canna Genetics sells seeds strictly as collectible souvenirs.
