Purple Weed Explained: Cannabis Strains, Terps & More

I remember the first time I grew a purple weed strain. What a blast! That epic feeling when you bring out the dank purple nugs from the bag…

Everybody starts mouth watering just at the mere sight of these babies.

And no, it isn’t just Purple Haze that has you drooling. 

The big secret to the amazing purple paradise?

It’s all an entirely natural process determined by plant genetics.

So, who’s in for a sick kick purple weed ride? 

Join(t) us below. We’re revealing the secrets of the purple-hued ganja feat—the ultimate purple bud superstars.

Purple Weed: Why Is Some Marijuana This Color? 

Purple cannabis strains keep gaining huge affection. Both the flavor and the potent effects are simply one of a kind and effortless to set apart from most strains.

But is this magic all due to the purple coloring?

So, why is some weed purple – WTF causes this color anyways?

In short, it’s because of plant genetics. Yeah, most strains don’t turn purple because they simply lack the purple gene.

Purple marijuana strains are just another insanely good example of the incredible plant intelligence of her Royal Ganja Majesty!


The pigment that causes the green color of weed is the good ol’ chlorophyll.

But purple strains have different compounds in their cells besides chlorophyll.

As highlighted in a 2019 study, the purple coloration results from a defense mechanism that aims to protect the plant.

Purple strains react to cool temperatures by producing a higher level of particular pigments. 

These pigments are called anthocyanins.

Psst, these same pigments are widely abundant in berries!

Anthocyanins belong to the family of flavonoids

Flavonoids are all-natural substances found in a wide variety of fruits, veggies, roots, stems, flowers, tea, wine, tree bark, grains, and, well, you guessed it…Weed!

Not Always Purple

Anthocyanins are not just purple in color. Anthocyanins appear as red pigments in acidic conditions and as blue pigments in alkaline conditions.

Apart from purple strains, anthocyanins give rise to the beloved pink weed strains, like Pink OG Kush.

Anthocyanins are valued for their high antioxidant properties. Yet anthocyanins have nothing to do with the taste and aroma of purple weed strains since these pigments are known to have no flavor.

Terpenes & Purple Pigments In Weed: The Golden Thread! 

In nature, it’s cold-weather adapted strains that turn purple.

Ultimately, the purple coloration in cannabis plants plays a function somewhat similar to terpenes.

Praise terpenes! We need an ode to terpenes! 

These aromatic molecules give cannabis strains their distinct flavor, and aroma. Also, they yield an array of additional wellness benefits for users, including the selective enhancement of cannabinoid activity.

Above all, terpenes are mighty plant protectors.

Terps repel unwanted visitors from harming the plant while attracting beneficial insects and pollinators.

Similarly, cannabis plants produce higher levels of anthocyanins and ensure the flowers’ well-being.

Purple Weed Secrets Revealed: The Science Of Cannabis Breeding 

A key point to keep in mind:

Most purple weed strains found in nature are Indicas, well-known to thrive in harsh climate conditions.

Holy Heavens, for the sweet love of holding a majestical purple Indica bud in your hands, what a blessing!

The potent body high with Indica strains get you glued to the couch in the most blissful, don’t-make-me-move-a-finger-I-am-busy-traveling-galaxies-right-now sort of high.

But nowadays, the purple strains you’ll find on the market are not just the good ol’ Indicas.

Hallelujah, we’ve gone a long way in understanding cannabis plant genetics through selective breeding, my precious bud buddies. 

A whole universe resides in the seemingly fragile cannabis seeds.

Thus, ganja breeders are creating many different purple-hued varieties to give us a punch, a purple punch, to be precise. 

This gives us plenty of room to experiment with purple weed and find our sweet spot.

Nonetheless, growers can apply another smart trick to trigger the purple marijuana to reveal its full glory.

For example, a purple strain can be intentionally exposed to cold temperatures during the dark cycle.

Also, LED lighting can help to bring out the best purple hues by stimulating the levels of anthocyanins to rise.

Purple Marijuana Exposed: Which Parts Of The Plants Turn Purple? 

  • Hairs – also known as pistils, the fluffy lil’ hairs can display purple color variations that don’t always last for long. However, with proper drying, some of the purple tones remain intact after the final stages of curing.
  • Resin glands – also known as calyxes, these parts of the cannabis plant can also turn purple and express strong, vivid purple coloring.
  • Trichomes – these tiny bubbles (aka the biochemical factories of the cannabis plant), can sometimes display purple coloring which is visible at the very end of the trichomes.
  • Foliage – the leaves of purple cannabis strains can also grant us a feast of purple nuances in varying levels; sometimes, the entire leaf turns striking, lucid purple; sometimes, only the very base, tips, and/or the edges of the leaves turn purplish.

Purple Weed Flavors 

I’ve noticed quite some confusion among ganja users when it comes to purple buds and their savory flavors.

Many people tend to think that their favorite purple bud strain gains its flavor due to the fact it’s purple.

That’s not really the case, though.

Indeed, purple weed strains often share some hints of fruity-grapey-berry thrill on your palate.

Yet ultimately, strains’ flavors depend on the type of terpenes involved, which has nothing to do with purple genetics.

Here are some succulent examples of the best purple weed strains. Let’s start with one of my personal all-time favorites.

Drumrolls, please!

Grandaddy Purple 

This was the first purple weed strain I grew in my garden. And oh boy, you can bet I felt like the purple strain Queen ninja pro while admiring this purple Indica masterpiece.

Crafted by the skillful west coast breeders, it’s a legendary cross between Purple Urkle and Big Bud.

Open up a jar of Grandaddy Purple (GDP) buds, and the aroma will immediately envelop the whole room!

Prepare to submerge in a fruity-grapey, sweet flavor symphony with hints of ginger, sharp skunk, and spice.

This delicious blend is due to the complex concerto of terpenes.

Keep in mind that both in purple plants and in “regular” ganja plants alike, terpenes are found in varying amounts. 

These amounts depend on marijuana seeds genetics, proper growing, drying, curing, and storage.


Simply put, terpenes are quite volatile.

Currently, experts are exploring new methods to preserve and augment terpenes. At the time of writing, there are over 200 terpenes identified in various cannabis strains!

Knowing the terpenes profile of your favorite weed strains is a real game-changer. 

The dominant terpenes found in Granddaddy Purple include:

  • Myrcene
  • Caryophyllene
  • Pinene
  • Limonene
  • Linalool

Purp Berry 


And another jaw-dropping purple weed strains masterpiece: Purple Berry!

Yet another whimsical representative of the purple-colored weed family.
