The best purple cannabis strains always seem to disappear quickly whenever you grow them: friends pop around more often, and suddenly your stash is gone.
So what makes a purple (or blue) strain that color, how do growers bring the color out, and does it change anything about the smoke?
This guide is for adults 21 and older where cannabis is legal. Marijuana is still a Schedule I controlled substance under US federal law (only FDA-approved products and state-licensed medical marijuana were moved to Schedule III in April 2026), and state laws on home growing differ.

Cannabinoid and terpene levels vary by grower, batch and growing conditions, so treat the notes below as general descriptions rather than lab results.

What Makes a Purple Cannabis Strain Purple?
Most plants contain pigments called anthocyanins, a type of flavonoid.
Don't confuse the term "flavonoid" with flavor: it comes from the Latin word for "yellow." Flavonoids do many jobs in plants, from signaling to protecting tissue.
Anthocyanins color plant tissue red, purple or blue, depending on pH. They help shield leaves from light stress, and they are why some tree leaves turn red in autumn.
Many cannabis plants can make some anthocyanin. In most strains, though, the conditions or genetics don't produce enough to show.
How to Grow Purple Marijuana Strains
Late in flowering, the plant's leaves break down chlorophyll and start to fade.
As the green fades, anthocyanin pigments become visible, giving leaves and buds a red, purple or blue tint.
Genetics matter most. Breeders have selected strains that color up reliably, so many modern purple strains turn purple in normal conditions.
How to Boost Color in Purple Cannabis Strains?
Growers often drop nighttime temperatures late in flowering to mimic cool autumn nights. In strains with the right genetics, this can deepen the color.
To sum up:
- Start with a strain bred for purple color; no technique will turn a green strain purple.
- Cooler nights late in flowering may bring out more color.
- Dry and cure buds carefully, and watch for bud rot and mold if you use cool, humid conditions.
- Treat additives that promise "purpling" with caution, since their claims are mostly marketing.
Benefits of Purple Weed
So, what makes purple weed special?
Honestly, as far as science is concerned: nothing proven.
Color does shape how we judge food and drink. When something looks appealing, we tend to expect it to taste better.
That is probably part of the purple-bud appeal. They look gorgeous, so it's easy to believe they have special effects.
Anthocyanins are studied in foods like berries, but there is no evidence that smoking or vaping purple cannabis delivers any health benefit. The FDA has not approved the cannabis plant for any medical use.
