What Makes A Great Purple Strain?
Purple flowers have always captured the attention of cannabis growers for their uniqueness. While appearance isn't what defines a truly exceptional cultivar, it's the first thing we notice, and first impressions matter.
Over the years, we've learned that some of the most memorable experiences can come from plants that look surprisingly ordinary. That is to say, it doesn't matter whether the buds are green or purple, airy or dense, or anything in between. Even if a flower doesn't look particularly impressive, always try the strain before making your final judgment.
Fortunately, as breeders, we have the opportunity to pursue both. Because we develop our genetics in our own breeding facilities, we're free to select for the characteristics we value most while also considering the visual appeal of every cultivar.
Potency, terpene complexity, resin production, vigor, and yield always come first, but when exceptional plants also express striking colors generation after generation, we see no reason not to preserve those qualities as well.
Although the color of a flower has little influence on its aroma, flavor, or effects, there's something undeniably special about a plant that naturally develops deep shades of purple, violet, lavender, red, or almost black as it reaches maturity. For many growers, those colors are part of the experience, transforming an already outstanding cultivar into something even more memorable.
That's why every cultivar featured here has been selectively bred over multiple generations for exceptional terpene profiles, strong performance, and all the characteristics that define a truly outstanding strain, while preserving the stable color expression that caught our attention in the first place.
This collection features the best purple strains with beautiful purple flowers, but it's the quality behind those colors that makes a strain worth growing again.
Our Top Purple Fast Flowering Strains
Purple Fast Flowering strains combine striking colours with unmatched speed and versatility that growers value.
Like traditional photoperiod cultivars, they can be cloned, making it easy to preserve and reproduce the same exceptional genetics for future grows, while their shorter flowering cycle can be of great help for both indoor and outdoor growers.
For growers looking to phenohunt, find and keep the ideal purple phenotype without sacrificing the flexibility of photoperiod genetics, Purple Fast Flowering strains are an ideal choice.
Purple Lemonade FF
Why I Picked It
Purple Lemonade FF is proof that speed doesn't have to come at the expense of bag appeal. Created as the photoperiod counterpart to our award-winning Purple Lemonade Auto, this unique Fast Flowering variety preserves everything that made the original a global favorite while offering the flexibility of photoperiod genetics with just as little as 7–8 weeks of flowering time.

Which Purple Strain Is Right For You?
Although all purple strains share their signature coloration, they can vary greatly in every other aspect. One purple cultivar can be completely different from another, just as green strains can differ in flavor, potency, structure, and effects.
Choosing to grow a purple strain is only the first step. From there, you'll want to consider factors such as terpene profile, plant size, potency, effects, flowering time, and yield to find the variety that best suits your preferences.
In our opinion, the best purple cultivars offer much more than eye-catching bag appeal. Stunning colors should be only one part of the package, flavor, resin production, potency, yields, and overall performance should be equally exceptional when talking about the best purple strains.
How I Selected These Strains
How I Selected These StrainsPurple flowers may grab everyone's attention, but they weren't the deciding factor when putting together this list. Modern cannabis breeding has produced countless colorful cultivars, yet only a handful combine purple coloration with the level of quality growers expect from top-tier genetics.
For this reason, every strain featured here was evaluated on much more than appearance. We looked for cultivars that consistently express purple hues while also delivering terpene production, abundant resin, yields, potency, and dependable performance across different growing environments. After all, there's little value in growing a beautiful plant if it falls short everywhere else.
Another important factor was consistency. All of these genetics have been grown by cultivators around the world and have built solid reputations through real-world results, not just breeding projects or promotional photos. That widespread feedback gives us confidence that what you see in the catalog is what you're likely to achieve in your own grow room.
The result is a collection of purple strains that showcase just how far modern cannabis breeding has come. Whether your priority is vibrant colors, loud terpene profiles, exceptional resin production, or simply growing something unforgettable, these are the cultivars we believe represent the very best purple genetics from our “purples” collection.
FAQ
The purple coloration comes from natural pigments called anthocyanins. Some cannabis genetics produce low levels and others produce high levels of these pigments, allowing flowers and leaves to develop shades of purple, violet, blue, or even black, especially during late flowering.
Not necessarily. Strains that have not been selectively bred to express purple coloration often require lower temperatures during the flowering stage to develop purple hues in their buds, leaves, or even resin. However, modern purple cultivars that have been specifically bred for this trait will naturally develop vibrant colors under standard growing conditions, without any extra effort.
No. Color has no direct relationship with potency. Purple strains can be just as strong, or even stronger, than green varieties, but it depends entirely on the cannabinoid content and has nothing to do with the colors.
Many modern purple strains are bred with terpenes in mind, so they can be super flavorful. However, just like with THC levels, it all comes down to the terpene profile and has nothing to do with the purple coloration.
While that may have been the case decades ago, modern breeding has eliminated many of the compromises found in older purple genetics. Today's high-quality purple cultivars can produce harvests comparable to those of the highest-yielding green strains.
Absolutely. Many purple strains are exceptional resin producers, making them excellent choices for hash and solventless extractions. In some cases, the trichomes themselves can develop a purple hue, resulting in eye-catching purple hash and extracts. As with any cultivar, selecting the right phenotype is key, but with the proper genetics, purple strains are fully capable of producing top-shelf concentrates.
Yes. In fact, this isn't limited to autoflowers. Feminized, fast flowering, and autoflowering strains are all capable of producing vibrant purple flowers, provided they have been bred to express this trait naturally or are grown under environmental conditions that encourage purple coloration.
Not at all. Purple coloration has nothing to do with how easy or difficult a strain is to grow. Traits such as vigor, resistance to pests and diseases, environmental resilience, and overall genetic stability have a much greater influence on cultivation than the plant's color. As with any cannabis variety, it's important to choose a strain that performs well in your intended growing environment, whether indoors, outdoors, or in a greenhouse. The same rule applies to every cultivar, regardless of whether it produces purple, green, or any other coloration.
That happens because a strain can express different phenotypes, even within the same genetic line. As a result, a purple strain may produce greener phenotypes, while a predominantly green strain may occasionally develop purple hues. Despite these differences in appearance, the flavor, aroma, and effects should remain largely the same, as they all belong to the same genetic line.
Yes. Given suitable growing conditions, purple strains can be grown successfully indoors, outdoors, in greenhouses, in DWC systems, in living soil or using any cultivation method you prefer. Just make sure you provide the right environment, and if you're growing quality genetics, the plant will take care of the rest.
