What is an Indica or Sativa?
Exploring Cannabis Varieties: Indica, Sativa, Ruderalis, Hybrids, and Landraces
Welcome to another installment in our series exploring the diverse world of cannabis! Beyond the individual compounds, the cannabis plant itself comes in a fascinating array of types, each with its own unique characteristics. Today, we're going to break down the main categories you might encounter.
The Main Types: Indica, Sativa, and Ruderalis
Historically, cannabis plants have been broadly categorized into three primary species based on their botanical characteristics and growth patterns:
​
-
Cannabis Sativa: These plants are typically tall and slender, with long, narrow leaves. They often thrive in warmer climates and can grow quite large. Their flowering periods tend to be longer than other types.
-
Cannabis Indica: In contrast, Indica plants are generally shorter, bushier, and have broader, darker leaves. They are often found in harsher, colder climates and tend to have a shorter flowering time.
-
Cannabis Ruderalis: This species is less commonly discussed in terms of its psychoactive properties. Ruderalis plants are small and hardy, known for their "autoflowering" trait, meaning they flower based on age rather than light cycles. They often grow in wild, challenging environments.
The Influence of Genetics: Terpenes and Flavonoids
While the classic Indica and Sativa classifications are helpful starting points, it's important to remember that the specific effects and aromas of a cannabis plant are largely due to its unique combination of compounds, particularly terpenes and flavonoids, alongside cannabinoids like THC and CBD (Journal of Natural Products, 2018; ACS Omega, 2021).
-
Terpenes are aromatic compounds found in many plants, including cannabis, that contribute to its distinctive scents (like citrus, pine, or earthy notes).
-
Flavonoids are another group of plant compounds that contribute to the plant's pigment and may also have their own set of characteristics.
The specific "profile" of these compounds can vary significantly even within the same broad classification, leading to a wide range of experiences.
Hybrids: The Best of Both Worlds
In modern cultivation, it's very common to find hybrid cannabis plants. These are created by crossing Indica and Sativa varieties (and sometimes Ruderalis) to combine desirable traits from both parents. Hybrids can be Indica-dominant, Sativa-dominant, or a more balanced mix, allowing for a vast spectrum of plant characteristics and compound profiles.
Landraces: Nature's Original Varieties
Before extensive cross-breeding, there were landrace cannabis strains. These are indigenous, wild varieties that have evolved over centuries in specific geographic locations, adapting to local environmental conditions. They represent the original genetic blueprints of cannabis from around the world and are often sought after for their unique and stable genetic traits. Examples include strains from Afghanistan, Colombia, and Thailand.
Conclusion: A Diverse and Evolving Plant
The world of cannabis varieties is rich and diverse, constantly evolving through natural adaptation and selective breeding. Understanding these different types – Indica, Sativa, Ruderalis, hybrids, and landraces – helps appreciate the complexity and botanical richness of this remarkable plant.
