Purple weed… How does it happen?

Purple marijuana strains are fast becoming the must have strains for growers, smokers and seed producers alike. The growing popularity of purple weed has seen it become a mainstay in medical dispensaries across the world with patients opting for the attractive buds of strains like Purple Haze ahead of more classic weed strains.

The majority of the time purple marijuana strains turn purple as a result of seasonal changes in temperature. However they do also require specific genetics to change to the highly coveted purple.

The knock on effect of the popularity of purple marijuana strains has seen seed producers hybridizing purple strains to provide more choice and a wider range of genetic make-up’s for the budding grower. Purple weed can be difficult to grow and whether or not the plant changes from classic green to a vibrant purple will depend on the creativity of the gardener.

The chemistry behind purple weed

Anthocyanins are responsible for the purple color found in weed. The word was created by German botanist, Ludwig Marquart. And it translates to “Blue Flower.”

Anthocyanins are water-soluble flavonoids that contain blue, purple and sometimes pink coloring pigments. Their job is to protect plants from light and an insect repellant. Some bugs assume the purple is a sign of an unhealthy plant.

These flavonoids can be found in plant tissues, leaves, fruits, and more. In fact, they give eggplants and blueberries their color.
When there’s not much light, chlorophyll production ceases. As a result, anthocyanins are produced in their place. Even a few anthocyanins present in cannabis is all it takes to bring out colors other than green.

Cannabis is what we consider to be a high plant (as in tall, no word-play here). High plants all possess a vascular system consisting of a xylem and phloem, structures that distribute nutrients and water throughout the plant. These high plants contain anthocyanins in all parts of the plant: leaves, flowers, fruits, stems, and even roots.

Depending on the genotype of the cannabis plant, these anthocyanins may be expressed in the latter part of the flowering period, irrespective of environmental conditions. They may also express in cold conditions. But if the plant does not produce enough anthocyanins, it might not affect the appearance of the plant at all.
