Purple cannabis carries a recessive gene from cool-climate landraces — particularly the Afghani highlands and the Pacific Northwest — that expresses anthocyanin pigments when temperatures drop during flowering. Strains like Granddaddy Purple, Purple Punch, and Purple Kush deliver heavy indica relaxation alongside bag appeal that's still unmatched on the dispensary shelf. The flavor leans grape, berry, and lavender; the effect leans body-heavy and sleep-inducing. Our Purple catalog focuses on strains that color reliably without sacrificing potency or terpene expression.

About the Purple family
The purple coloration isn't a strain effect — it's a stress response. When night-time temperatures drop below about 60°F during the last 2-3 weeks of flower, chlorophyll breaks down and the underlying anthocyanin pigments become visible. Some strains carry the genetics to express this strongly; most don't. The visual difference at harvest is the reason Purple strains command a premium at dispensaries even when potency is average.
Growers chasing purple buds run their lights-off temperature lower than usual in late flower — sometimes intentionally dropping it to 55°F — to coax the color out. This works for genetically purple strains and does nothing for strains that don't carry the gene.
Flavor-wise, Purple lineage runs grape, blueberry, lavender, and sweet-cream — driven mostly by myrcene, linalool, and pinene. The effect is the heaviest in this catalog: deep body relaxation, slowed thought, eventual sleep. Most Purple strains lean 80%+ indica and produce a high that's hard to confuse with anything else.
Frequently asked questions
Why do some cannabis strains turn purple?
Purple coloration is caused by anthocyanin pigments that become visible when chlorophyll breaks down at low temperatures. Strains genetically prone to this — typically those with Afghani or Pacific Northwest landrace heritage — turn purple when night-time temperatures during late flower drop below ~60°F.
Are purple strains stronger than regular cannabis?
No — color and potency are unrelated. The anthocyanin pigments that produce purple coloration have no psychoactive effect. Strain potency depends on cannabinoid content, which varies independently of color. Purple strains range from low to very high THC.
What is the most popular purple strain?
Granddaddy Purple (also called GDP) is the most widely-grown purple strain in the United States — a 2003 Bay Area cross of Purple Urkle and Big Bud that combines deep purple coloration with heavy yields. Other prominent purple strains include Purple Punch, Purple Kush, and Purple Haze.
