A Guide To Cannabis Landrace Strains

Landrace Strains

Weed growers around the world continue to create new cannabis cultivars by crossbreeding existing strains. As a result, many modern-day marijuana cultivars are hybrids, but their genetics all come from ancient landrace strains.

Join us to learn more about these original cannabis strains. We’ll explore where weed comes from, how to identify and source landrace cultivars, and which cultivars are considered original marijuana strains.

Let’s dive in!

Where did weed come from?

First things first—where did weed come from? Let’s check out the genetic history of marijuana.

Cannabis has existed for millennia, and we can trace its use as far back as 2900 B.C.E. Historians believe our ancestors used this magical green plant for many things, including food, medicine, building and clothing material, and probably to get high.

It’s believed every marijuana strain that exists today can be traced back to a single landrace strain originating from the Himalayan foothills—today’s border between Afghanistan and Pakistan.

As early explorers traveled through the Hindu Kush area, they stumbled upon this landrace cannabis strain and took it along on their trips. It quickly spread across the globe.

Marijuana quickly became popular in China and India, where people used it in herbal medicine and religious practices. Next, it made its way to Europe, and by the 18th century, landrace marijuana strains spread all over the world.

Due to the constant transplantations, these weed strains began to adapt and evolve, allowing them to flourish in new climates. This non-selective breeding led to the great cannabis revolution and the birth of the hundreds of different marijuana strains that exist today.

What is a landrace strain?

The word ‘landrace’ is derived from the German, Dutch, and Danish languages and refers to the origin of something.

In short, landraces are cannabis plants that naturally grow in a specific area and are indigenous to that region. These strains haven’t been crossed with any other cultivar and contain pure and unaltered genetics.

Also referred to as original weed strains, landraces are the oldest known cannabis cultivars. After their discovery, they traveled, resulting in genetic mutations to help them adapt to the local conditions. As such, landraces can survive in various types of soil and weather.

These environmental changes also led to the evolution of landrace strains’ physical characteristics. However, every original strain carries its geographical history and true genetics in its genome.

Most of the time, landrace strains are named after the area they come from. There are only about 100 of these cultivars in existence, and they’re typically either a pure sativa or indica—there are no hybrid landraces.

Why are landrace strains unique?

Landrace strains are the oldest cannabis cultivars in existence. They grow naturally and don’t need any human help to flourish. 

Original strains have never been crossbred with other cultivars, which means their genes are pure and not the result of human interference. 

If you’re lucky enough to encounter a real landrace strain, you’ll instantly notice its distinct flavors, aromas, and effects. These traits are vastly different from modern cannabis hybrids.

If multiple marijuana landrace strains hail from the same area, they typically share similar characteristics. The consistency between these plants is unmatched, and you can expect an equal dose of medical and psychoactive qualities.

Keep in mind that once you remove a landrace strain from its original habitat, it loses its authenticity, as replicating the exact conditions it grew in is almost impossible.

What’s the difference between landrace strains and regular strains?

The distinction between a landrace and a regular strain lies in genetics. The majority of cannabis cultivars today are hybrids, which means they’re a product of selective breeding.

Here are some of the various marijuana hybrids you can encounter:

  • High THC levels and minimal CBD.
  • High CBD levels and minimal THC.
  • Unusual physical traits, like purple-hued buds.
  • Ones with a complex terpene profile that results in unique flavors and aromas.

On the other hand, landrace strains contain pure genetics and have never been bred. They’re classified as either a sativa or an indica, while regular strains are either sativa-dominant or indica-dominant—making them hybrids.

How do you know if a cannabis strain is really a landrace?

These days, it’s almost impossible to find pure landrace strains. Over the years, breeders have diluted their original genetics by removing them from their native habitat and exposing them to new growing conditions.

Every time a new phenotype enters the mix, it gets a little less of the original landrace strain’s prized genetics.

The only way to tell if you’ve got a landrace strain is by visiting the region it’s from and getting some yourself or by trusting a reliable cannabis seed bank. However, you most likely won’t be able to find a pure landrace, as they’re extremely scarce.

Are landrace strains still around?

Breeders only began crossbreeding sativa and indica landrace strains during the late 1970s. This practice allowed them to produce marijuana plants with the best characteristics of both strains while eliminating unwanted traits.

Although landrace weed strains are the cornerstone of cannabis creation, they come with several disadvantages, including:

  • Difficult to cultivate
  • Slow growing time
  • Low potency
  • Small yields

Modern hybrids don’t have as many drawbacks. They’re usually bred for rapid growth, massive yields, and sky-high THC levels.

Pure landrace strains typically don’t appeal to everyday marijuana growers and consumers, but they’re vital to professional breeders and seed banks. These individuals and organizations have enormous collections of rare landrace seeds for the purpose of preservation and future crossbreeding.

In short, landrace are still around, but they’re rare and not the ideal choice for regular cannabis growers and consumers.

How many landrace weed strains are there?

Nobody knows precisely how many landrace strains exist, and cannabis enthusiasts constantly argue about which cultivars make the list and which ones don’t. However, the consensus is that there are less than 100 original cannabis strains around.

Why is it so hard to find landrace marijuana strains?

Due to their less desirable traits, growers aren’t cultivating landrace strains on a large scale anymore. It’s difficult to get your hands on certain landrace cultivars, but some are still in circulation.

Nowadays, original strains are commonly called heirloom strains. Although they carry the true genetics of the landrace, they aren’t indigenous to their current environment.

Heirloom strains were removed from their natural habitat and planted in a different location. With the assistance of breeders, they managed to adapt to their conditions but weren’t deemed as pure as their landrace ancestors. Nonetheless, heirloom strains still have more of the original genetics than hybrids.

Cannabis landrace strains list: what strains are landrace?

In cannabis culture, many people classify strains as either sativa or indica, typically describing the effects. However, these terms can also tell you a lot about where the strain originated from.

Remember, modern hybrids are either sativa- or indica-dominant, while landrace strains are pure sativas or indicas.

Landrace sativa strains originally grew in tropical places. The lack of water coupled with long and hot days resulted in slender weed plants that reached over six feet tall. Sativa strains have narrow, delicate foliage and a longer flowering cycle than indicas.

The effects of sativa strains are more energizing, uplifting, and creative. They pair well with socializing and artistic endeavors. Some of the common medicinal benefits include relief from anxiety and depression and an increase in appetite.

Landrace indica strains originally grew in mountainous regions further away from the equator’s heat. Indica plants are hardy and can survive the short summers and cold winters synonymous with their natural environment. They tend to produce short and bushy crops with large, broad leaves and have a shorter flowering cycle than sativas.

The effects of indica strains are relaxing, calming, and somewhat sedating. They’re best used for a mellow evening surrounded by your favorite snacks. Their medicinal benefits include relief from chronic pain, insomnia, and muscle spasms.

Landrace indica strains vs. landrace sativa strains

The two types of landrace strains are indica and sativa, which differ based on their natural habitat, physical appearance, and the effects they produce.

Indica landraces are native to mountainous regions with harsh climates. They develop into smaller plants with bushier foliage and more resin. Due to colder weather conditions, they go through a shorter flowering phase. The buds produce an intensely relaxing sensation.

Sativa landraces flourish in warmer and dryer environments, growing taller crops with a longer blooming period. The nugs generally contain lower CBD levels and higher THC, offering a cerebral buzz that energizes and motivates.

If you’re looking to experience pure indica or sativa effects, below are some of the most sought-after landrace strains. Let’s check out some of the best landrace strains:


If you want a landrace with the purest indica genetics, this is it. Afghani hails from the Middle East and made its way to the US sometime during the 1970s, right before the war on cannabis began.

It offers a deeply relaxing and sedating high that effectively manages medical conditions like chronic pain, fibromyalgia, and insomnia. Afghani produces super resinous cannabis plants. This powerful strain contains earthy, herbal, pine, and spicy flavors.

Hindu Kush

Believed by many to be the original forefather of cannabis, Hindu Kush boasts 100% indica genetics. This landrace strain originates from the Hindu Kush mountain range on the border between Afghanistan and Pakistan.

Hindu Kush arrived in the US during the 1960s. It delivers relaxing, sedating, and slightly euphoric effects. Revered for its deep earthy flavor, Hindu Kush also emits refreshing citrus, pine, and lemon notes.

CBD Carmagnola Landrace stands as a testament to the enduring legacy of landrace strains, delivering a pure and therapeutic CBD experience rooted in tradition and natural excellence.

What’s the strongest landrace strain?

As we mentioned earlier, landrace marijuana strains aren’t as powerful as modern hybrids. Through crossbreeding, growers can select the most desirable strains and produce weed plants with the best characteristics of these cultivars.

Landrace strains don’t have these benefits and are tied to their original genetics. If you want a taste of the most powerful original strain, we suggest giving Durban Poison a try for sativa and Afghani for indica.
