FAQ — Rare Purple Cannabis Strains
- Why do some cannabis strains turn purple?
The purple color is caused by a high concentration of anthocyanins — natural plant pigments. Their expression depends on the genetics and environmental conditions. In rare purple cannabis strains, this trait is genetically stabilized and shows vividly in buds and leaves.
- Does purple color mean higher THC levels?
Not necessarily. Color doesn’t determine potency. Many purple strains are indica-dominant, known for relaxing effects, but THC levels depend on genetics and the terpene and cannabinoid profile.
- What do purple strains smell like?
Purple buds often feature fruity, sweet, and slightly spicy aromas, with notes of grapes and berries. They typically contain terpenes such as myrcene and linalool, which add floral smoothness and complexity.
- Why are purple strains considered rare?
Developing a stable purple phenotype requires years of genetic selection. Breeders must preserve the color without losing aroma or stability. That’s why these genetics are released in limited editions and highly valued among collectors.
- Do purple plants need cold temperatures to change color?
Cooler night temperatures can enhance pigmentation, but high-quality purple genetics express color naturally. The main factor is the genetic code, not temperature.
- Which purple strains are available from Pyramid Seeds?
Some of the most iconic are Purple, Mendocino Purple Kush and Purple Urkle x Blue Pyramid, all known for vivid hues, sweet terpenes, and dense resin production.
- Are purple strains suitable for beginners?
Yes. Many purple strains are compact, stable, and aromatic — perfect for collectors looking for visually striking and flavorful genetics.
- Why are purple strains valuable in collections?
Rare purple cannabis strains combine visual beauty, unique terpene profiles, and limited availability, making them standout additions to any premium seed collection.
