Purple Cannabis Seeds — Anthocyanin-Rich Genetics for Striking Australian Harvests
Purple seeds produce plants with vivid violet, plum, and near-black colouration in their flowers and foliage. The colour comes from anthocyanin pigments — the same compounds that colour blueberries and red grapes — and is amplified by cool nighttime temperatures during late bloom. Beyond visual drama, purple cultivars often carry unique grape, berry, and floral terpene profiles that set them apart on flavour.

The Science of Purple Cannabis
Purple colouration in cannabis is produced by anthocyanin pigments — water-soluble flavonoids that shift colour based on pH. The same molecular family colours blueberries, red cabbage, and grape skins. Certain cannabis genotypes carry elevated anthocyanin production as a heritable trait. Cool nighttime temperatures (15–18°C) during the final two to three weeks of flowering trigger and intensify the colour shift. Crucially, the genetic predisposition must be present — lowering temperature alone will not turn a green strain purple. Every cultivar in our purple genetics section is bred for strong anthocyanin expression.
