The Truth About Purple Weed: What It Is & Why It's Purple

Why Weed Leaves Turn Purple

The short answer to why weed leaves turn purple is genetics, temperature, nutrient deficiencies, and light exposure. 

All these factors contribute to the weed flowers and leaves turning purple. 

Let’s explore each of these factors in detail:

Factors that Directly Cause Purple on Weed

1. Genetics/Anthocyanins

Some specific cannabis strains have water-soluble pigments known as anthocyanins. 

These anthocyanins are responsible for the weed’s purple color. These can give blue, red, and purple colors depending on the pH level of cannabis plants.

  • If pH < 7: Anthocyanins give the weed a red color 
  • If pH ≈ 7: Anthocyanins give the weed a purple color
  • If pH > 7: Anthocyanins give the weed a blue color

 These pigments, also found in blueberries, redberries, and plums, give them their colors. 

Granddaddy Purple and Purple Haze are strains with a bright purple color because they are rich in anthocyanins.

Factors that Indirectly Cause Purple on Weed

From now on, everything we discuss will indirectly contribute to some cannabis turning purple. 

By ‘indirectly,’ we mean these factors influence anthocyanins, which then make the purple flower weed.

1. Temperature

Temperature is one of the reasons that gives weed leaves a purple hue. 

Cooler temperatures activate anthocyanins. 

Cannabis plants experience a reduction in chlorophyll at  50°F or 10°C. 

The purple hue on the weed becomes more visible as the chlorophyll fades and anthocyanins become more dominant.

2. Light

The light turns weed leaves purple. 

Yes, UV exposure enhances anthocyanin production in cannabis. 

The more anthocyanins, the greater the chance that the weed will develop a purple hue.

Is purple weed stronger than green or red?

Now, onto the burning question—is purple weed stronger than regular weed? 

The answer is a clear No.

It has been confirm that the color of the weed doesn’t determine whether purple weed is better or stronger than green weed.

Granddaddy Purple and Purple Haze are fan favorites for their strong potency. However, plenty of green strains offer the same powerful effects. ​

The quality or potency of weed depends on cultivation methods, terpene content, and the cannabinoids it contains.

Frequently Asked Questions (FAQs)

Why is some weed purple?

Weed turns purple due to high levels of anthocyanins. Anthocyanins are pigments that give cannabis purple or red color. Anthocyanins become more visible as chlorophyll breaks down due to cold temperatures and light exposure. So, the higher the anthocyanins, the more the chances of cannabis flowers to turn purple.

No, it’s not true that purple weed is better than regular weed. The high comes from the cannabinoids and terpenes present in the plant, not its color. Some people enjoy purple strains for their aesthetics, but they don’t necessarily taste or work better than green ones. You can consume purple weed like any other strain because it is not harmful, just like regular weed.

“Purple weed” is a general term for any weed species with purple-colored leaves or flowers, often including deadnettle, henbit, and thistles. It is not a single species but a visual classification.

Purple coloration in plants is caused by anthocyanins, natural pigments produced due to genetics, cold temperatures, nutrient stress (especially phosphorus), or environmental factors.

Common weeds with purple flowers include Henbit (Lamium amplexicaule), Purple Deadnettle (Lamium purpureum), Creeping Charlie (Glechoma hederacea), and Thistle species. Identification depends on leaf shape, growth pattern, and flower structure.

If plant material releases purple color in water, it’s due to anthocyanin pigments dissolving, which can happen when cells break down or are damaged. This is normal and not harmful.

To remove purple weeds:

  • Hand-pull when soil is moist (remove roots)
  • Apply a selective broadleaf herbicide (2,4-D, dicamba)
  • Maintain a dense, healthy lawn (mowing, fertilizing, overseeding)
  • Prevent regrowth with pre-emergent herbicides
