Purple Cannabis Explained: What Causes the Color Change?

In the world of cannabis, green may be the most familiar color—but it’s certainly not the only one. From deep violet hues to bright lavender tones, Purple Cannabis continues to captivate consumers with its striking appearance and unique aroma. But what actually causes cannabis to turn purple? Is it better than green weed? And does the color affect potency?

In this guide, we’ll break down the science behind Purple Cannabis, uncover the environmental and genetic factors behind its color, explore the possible benefits of purple weed, and recommend where to find premium purple strains online. Spoiler alert: Bud Cargo is your go-to source.

Understanding Purple Cannabis: More Than Just a Pretty Bud

The term Purple Cannabis refers to marijuana strains that display purple hues in their buds, leaves, or stems. While the vibrant color is aesthetically appealing, it also tells us a lot about the plant’s genetics and growing conditions.

Although most cannabis is green due to its high chlorophyll content, certain strains can develop rich purple shades thanks to compounds called anthocyanins—the same pigments found in blueberries, grapes, and eggplants.

What Causes Cannabis to Turn Purple? The Science Behind the Color

So, how exactly does cannabis go from green to purple? Several key factors come into play. Let’s explore the science behind this transformation.

1. Anthocyanins: The Pigments Behind Purple Cannabis Strains

Anthocyanins are flavonoid compounds that produce red, purple, and blue hues in many plants. In cannabis, these pigments are found in the trichomes, leaves, and buds, especially in strains with the right genetic makeup.

Interestingly, anthocyanins only become visible when chlorophyll production slows down—usually during colder temperatures. That’s why many growers notice color changes late in the flowering stage.

2. Temperature and Light Exposure: The Environmental Triggers

Colder temperatures, particularly at night, can suppress chlorophyll and activate anthocyanin expression. As a result, cannabis may begin turning purple just before harvest.

However, the shift won’t happen unless the strain already carries the genetic potential to produce these pigments.

Light cycles, intensity, and even UV exposure can also influence coloration—but again, the genetics must support it.

Genetics Matter: Why Not All Weed Turns Purple

Not all cannabis strains can turn purple, even under ideal environmental conditions. The genetic blueprint of the plant is the most important determining factor.

Common Purple Cannabis Strains

• Granddaddy Purple (GDP)
• Purple Kush
• Purple Haze
• Blackberry Kush
• Purple Urkle

These strains are bred specifically for their colorful appearances and soothing indica-dominant effects. Thanks to selective breeding, purple strains are more available than ever—but some phenotypes remain incredibly rare.

Is Purple Cannabis More Potent?

One of the most common myths about Purple Cannabis is that it’s automatically stronger than green weed. While its appearance might suggest premium quality, color alone doesn’t determine potency.

THC Levels Are Not Color-Dependent

• Cannabinoids like THC and CBD are colorless
• The presence of purple pigments doesn’t increase psychoactive effects
• However, purple strains often have rich terpene profiles, influencing aroma and flavor

That being said, many Purple Cannabis strains are potent due to strong genetics—not because of the color itself.

Flavor and Aroma: The Terpene Connection to Purple Buds

While the color may not influence THC content, it often correlates with unique terpene combinations. In fact, many Purple Cannabis strains offer rich, berry-like flavors that are hard to find in traditional green strains.

Common Terpenes in Purple Strains

• Myrcene – Earthy and musky; promotes relaxation
• Linalool – Floral and calming
• Pinene – Offers a pine-like freshness
• Caryophyllene – Spicy and anti-inflammatory

Thanks to these terpenes, purple strains typically deliver a sweet, fruity, and soothing experience, which may contribute to their popularity for evening use.

Purple Cannabis Benefits: More Than Just Looks?

Beyond their eye-catching appearance, many Purple Cannabis strains offer therapeutic benefits—particularly for medical users.

Potential Wellness Benefits

• Stress and anxiety relief: Purple strains are often indica-dominant, known for their calming effects.
• Pain management: High-myrcene strains may help with chronic pain.
• Insomnia support: Many users report improved sleep quality.
• Mood elevation: Terpenes like linalool and pinene may uplift and relax simultaneously.

Because of these benefits, Purple Cannabis is often chosen by those seeking relief from physical and mental stress.

Is It Safe to Smoke Purple Weed?

Yes! Purple Cannabis is completely safe to consume, as long as it is grown properly and lab-tested. The color is a natural part of the plant’s biology, not the result of artificial dyes or additives.

However, it’s important to source your cannabis from a trusted dispensary to ensure quality, purity, and safety.
