A top view of three blue cannabis flowers

Descending from a mighty genetic line, Blue cannabis strains boast excellent potency; unique aromas and flavours, and a history that’s almost 40 years old. But what Blue cannabis strains are the cream of their crop and truly deserve a place in your garden?

Acapulco Gold, Purple Haze, and Red Lebanese – cannabis strains often get named after colours. And some of the hottest strains on the market right now are those tagged ‘blue’.

Unlike the aforementioned varieties, however, Blue cannabis strains don’t get their name from their colour, but rather their genetics.

Keep reading to learn all there is to know about blue weed strains; what makes them special, and a hand-picked selection of the best blue strains that you can grow at home today.

What are blue cannabis strains?  An awe-inspiring list of strains with buds as blue as the ocean? Sorry to burst your bubble, but not all blue cannabis strains actually develop blue flowers. In fact, blue is a fairly rare colour to find in cannabis – much rarer than pink or purple, for example.

Instead, blue cannabis strains are considered “blue” because they descend from Blueberry – a classic hybrid created by the legendary breeder DJ Short. Mother of the Blue genetic line, Blueberry, dates to the 1980s and continues to be on the lips (and in the lungs) of modern-day smokers.

The 7 best blue strains

Thanks to the hard work of cannabis breeders from around the globe, the Blue genetic line now comprises hundreds of varieties that combine Blueberry’s unique aromas, flavours, and potency with those of both classic and modern strains.

Ready to explore the world of blue weed? Do so with these fantastic blue strains:

1. Blueberry

Genetics: Highland Thai x Pink Thai x Afghani Indica

Aromas/flavours: Berries, honey, and fruit

Breeder: DJ Short

No list of blue cannabis strains is complete without the mention of Blueberry – the mother of all blue strains created by DJ Short.

Originally from Detroit, DJ Short began his work as a breeder in the late 1970s, working predominantly with landrace strains native to the Americas, Asia, and the Middle East. By the 1980s he’d created a stabilised line of unique hybrids which contained arguably his most prized creations – Blueberry and Flo.

Descending from a unique mix of Highland Thai, Pink Thai, and Afghani indica, Blueberry is a true hybrid with a great mix of sativa and indica traits. She introduced smokers to novel aromas of sweet ripe berries and rich honey that, to this day, are highly sought-after.

Finally, Blueberry is also loved for delivering a deeply relaxing physical effect that soothes the body while relieving mental tension.

2. Blue Dream

Genetics: Blueberry x Haze

Aromas/flavours: Berries, fruit, flowers, and citrus

Breeder: Unknown

Blue Dream is arguably the second-most popular strain in the Blue family, and for good reason. Descending from DJ Short’s Blueberry and a classic cut of Haze, this strain boasts all-star genetics, delicious aromas/flavours, and potent effects.

Break apart a big, frosty nug of Blue Dream and you’ll enjoy wafting sweet aromas that combine upfront berry notes, floral hints, and refreshing citrus overtones. Her flavour is similar, with some slightly earthy undertones, and her effects instil both an uplifting cerebral euphoria and a long-lasting physical buzz.

3. Blue Bullet

Genetics: Skunk #1 x Blueberry

Aromas/flavours: Berries, fruit, and pungent skunk

Breeder: Sensi Seeds

Originally called Sensi #119, Blue Bullet got its name from the Sensi Seeds’ community who treasured this variety for its speed, impressive genetics, and delicious aromas.

By crossing DJ Short’s Blueberry with our in-house Skunk #1 Auto, our breeders created a fast and compact seed that boasts all the best auto traits without skimping on aroma or potency.

Thanks to her indica genetics, this strain is well-suited to cold climates. Plus, the influence of Skunk #1 Auto means this strain can go from seed to harvest in weeks all with minimal care.

Come harvest time, our Blue Bullet will reward you with big, frosty flowers riddled with bold berry and skunk aromas that pack a well-balanced high – expect to feel both physically relaxed and uplifted/chatty.

4. Blue Cheese

Genetics: Blueberry x UK Cheese

Aromas/flavours: Pungent cheese and sweet berries

Breeder: Big Buddha Seeds

UK Cheese sent ripples across the cannabis world when it crashed onto the scene in the 1990s. Believed to be a unique Skunk #1 phenotype with ridiculously funky aromas, Cheese was discovered in the UK and became associated with The Exodus Collective – an underground group from Luton, England known for throwing mean parties and openly protesting for the legalization of cannabis.

For a long time, Cheese was a clone-only strain. However, it was stabilised as a seed in 2002 by Big Buddha Seeds, a bank that’s now famous for its ever-growing list of Cheese varieties.

Blue Cheese, you guessed it, is a cross of original UK Cheese and Blueberry. Boasting a unique mix of berry and cheese terpenes along with a heavy stone, Big Buddha’s Blue Cheese has won numerous cannabis cups and is a must-try strain for smokers with a daring palate.

5. Blueberry Zkittlez

Genetics: Blueberry x NL#5 x Skunk Kush x Durban

Aromas/flavours: Berries, citrus, and tropical fruits

Breeder: Sensi Seeds

Now known as The Original Z, Zkittlez is a modern US indica and arguably the mother of all candy strains. Boasting rich aromas reminiscent of the fruit candy she’s named after, Zkittlez introduced smokers to aroma and flavour profiles never before seen in cannabis.

To meet the ever-growing demand for sweet terpenes, our breeders created Blueberry Zkittlez; a unique cross stemming from Blueberry, Northern Lights, Kush, Skunk, and Durban. Talk about celebrity genes!

A super fruity hybrid with sugary-sweet aromas and flavours reminiscent of berries, grapefruit, oranges, and pineapple, Blueberry Zkittlez is ideal for vaping and delivers a strong effect.

Expect an initial cerebral euphoria that transforms into a deeply soothing full-body stone – ideal for laidback afternoon/evening sessions and relaxation.

6. Blue Skunk

Genetics: Blueberry x Shiva Skunk x Hindu Kush

Aromas/flavours: Berries, earth, chocolate, and hash

Breeder: Sensi Seeds

Love the earthy, pungent stank of Skunk and Kush? This is the strain for you; stemming from a three-way cross of Blueberry, Shiva Skunk, and Hindu Kush, our Blue Skunk combines the best traits from all these famous strains.

Expect big, resinous flowers loaded with frosty trichomes that combine the aromas of ripe berries with earthy undertones; hints of musky sandalwood; spice, and pungent hashish. At the same time, you’ll enjoy strong effects that are cerebral, creative, and social at first before turning to the body and producing long-lasting waves of relaxation.

Best of all, thanks to her all-star genetics, our Blue Skunk seeds are easy to grow in virtually any setup, sprouting into compact and hardy indica plants capable of producing heavy harvests in express time.

7. Blue Sunset

Genetics: (Buffalo Blue x Blue Satellite 2.2) x Runtz

Aromas/flavours: Blueberries and citrus

Breeder: Sensi Seeds and Sherbinskis

Last but definitely not least on this list of the best blue strains is Blue Sunset – a new variety that gets its name from its stunning dark hues as well as the fact that we created it in collaboration with Sherbinskis (aka Mario Guzman); the creator of modern classics like Sunset Sherbet, Pink Panties, and Gelato.

Slightly indica-dominant, Blue Sunset produces dense, frosty flowers packed with resinous trichomes. Break apart one of her dense nugs and rejoice in her rich aroma, which combines notes of sweet berries with fresh, juicy citrus fruits.

Then, minutes after your first toke, enjoy as Blue Sunset elevates your mind with an uplifting sativa rush that gradually subsides into a warm body buzz – the perfect strain for social settings, weekends, or virtually anytime you want to feel positive, carefree, and relaxed.
