Check these purple buds from the Oregon Breeders Group^[1], and hear what member Wade Preble has to say about their newest Sirius Black line.

“For a few years the Oregon Breeders group has been trying is on the forefront of developing the ultimate deep purple strain. The breakthrough came when we crossed two strains that had minimal purple color, and the offspring came out much darker than their parents and completely purple. This new cross became the catalyst for the Sirius Black project. Additional hybridizing lead to us perfecting the smell and taste of our newest strain, Sirius Black. The current version of Sirius Black looks, smells and tastes incredible. The hybridizing technique involved multiple crosses, educated guesses, and a little luck.

Sirius Psychedelic is another new strain we are working on. It has green, pink, red and purple hues. It is a work in progress, but it is a beautiful multicolored flower.

We hope to increase the purple gland heads in these strains, with the goal of developing purple non-solvent hash and perhaps purple oil in the near future. The Oregon Breeders Group, Milwaukie Organic Farms, and Sirius Extracts are all committed to taking cannabis to a new level.”

Compare some of these close-up photos with the HIGH TIMES diagram of the Anatomy of a Trichome^[2]. You will see most of the pink and purple hues are located in the epidermal cells, the skin of the trichome stalk, and in the secretory cells in the base of the trichome head. As of yet, growers and scientists do not know the source of these colors that form in cannabis.
