9 Best Purple Strains

One of cannabis consumers’ biggest obsessions is purple buds, renowned for their high quality, bold terpenes, and extreme potency. Purple strains have been around since the introduction of cannabis into Western society, and to this day, their popularity has never faded.

What are anthocyanins, and how do they affect purple strains?

Anthocyanins are water-soluble pigments that produce a wide variety of red, blue and purple hues throughout the flowering stage. They are from the family of compounds called flavonoids. So when you look at Blackberry Cake and see purple hues in the flowers, or look at Panama Red and see reddish colors on the leaves, it’s because of anthocyanins. Many fruits like blueberries, blackberries, and strawberries, also have high concentrations of anthocyanins.

Multiple factors influence the anthocyanins in cannabis plants. However, climate and genetics are the two most important. Simply put, the colder the temperature during a cannabis plant’s flowering stage, the more prone the plant is to produce purple-hued leaves and buds.

However, not all cannabis plants can thrive in cold weather. This is a big reason why the majority of purple cannabis strains are indica-dominant. Indica strains can always be traced back to Afghan landrace genetics, and as every cultivator knows: Afghan genetics love a continental climate.

If you want to cultivate some outstanding purple genetics, we have composed a list of the nine best strains for you!

1. Purple Bud

Purple Bud is a world-renowned indica-dominant strain created from crossing an Afghan-Jamaican with California Purple Kush. It was bred to honor the iconic indica genetics of the Hindu mountain range.

With an iconic terpene profile that features an abundance of myrcene and caryophyllene, your taste buds can pick up sweet pine and sandalwood notes with fresh berry undertones. Before being overcome by deep earthy notes reminding you of other classic indicas! The effects of this iconic purple cultivar start with a cerebral high, with an uplifting euphoria that dissipates into a long-lasting full-body stone, leaving consumers feeling cerebrally energetic and focused while soothing the body.

This strain is ideal for indoor and outdoor cultivation and can even thrive in a colder continental climate. Due to its heavy indica lineage, plants are short and stocky with short internodal gaps. Growers can expect an average flowering time of 63 days, with the potential for yields of over 600 grams outside. In classic indica form, the bud structure is dense with purples, hues scattered throughout and darker foliage.

Purple Bud is an ideal low-maintenance strain and perfect for beginners!

2. Granddaddy Purple

Granddaddy Purple (GDP) was created by breeding Purple Urkle with Big Bud. It’s a world-famous indica that has dominated numerous cannabis cups, taking first place at the Green Cup and Denver High Times Cannabis Cup. With its outstanding THC levels, it was bred for the American medicinal market in the early 2000s and is often credited as the granddaddy of purple cultivars.

When you smell fresh Granddaddy Purple, you get a staunch earthy aroma with a vibrant sweetness. The lusciously sweet aroma comes from a terpene profile dominant in myrcene, pinene, and caryophyllene, with flavors reminiscent of fresh grapes and sweet sugary candy dominating your palate. A deliciously sweet aroma takes over the senses, and Granddaddy Purple cannot be forgotten!

Dank, musky notes give-away to sweet undertones of fresh grapes and berries. However, the cultivar’s effects are just as lovely as its terpene profile! Purple Urkle is an evening strain, and its effects induce a lethargic and soothing body-stone.
