A Guide to the Lesser-Known Cannabis Ruderalis


Sativa and Indica are no doubt the most well-known types of cannabis. A lesser-known cannabis species is cannabis Ruderalis, which is packed with characteristics that make it attractive to both growers and consumers who need it for specific medicinal effects.

You should have no trouble with Ruderalis pronunciation as it reads just as it’s written. According to botanists, a ruderal is a plant that grows, despite the environment, as it is able to withstand harsh conditions. True to its name, cannabis Ruderalis is highly resilient and commonly grows along roadsides, fallow agricultural land, or any other agricultural land once disturbed by humans before being left alone.

Historically, cannabis Ruderalis traces its origins to Russia, before it spread out throughout Central Asia and central and eastern Europe. This species was first classified by a Russian botanist, D.E Janischewski, who, after studying the structure of the plant, noticed how it differed from other already classified cannabis plants.

Cannabis Ruderalis Characteristics

It is believed that cannabis Ruderalis developed its characteristics in response to exposure to extreme cold or heat, low humidity levels, not enough or too much light, among other harsh climatic conditions.

The distinguishing characteristic is that cannabis Ruderalis is auto-flowering.  This means that, unlike, Sativa and Indica, this species will transition from the vegetative state into the flowering phase irrespective of whether there is a change in the light cycle or photoperiod, that is, the ratio of dark to light hours. For the other species, growers have to trigger the flowering phase by adjusting the lighting.

The auto-flowering cannabis Ruderalis buds will begin to flower on their own, within 3-4 weeks after they sprout from the seeds. This distinct characteristic means that cannabis Ruderalis can grow just about anywhere and flower throughout the year.

Other key characteristics include

  • Grows to up to only about 1-2.5 feet tall, making it the smallest among the cannabis plants. The small stature has earned it the name ”dwarf cannabis”
  • Ruderalis buds are small and dense
  • Thick stem and braches
  • Highly resilient in harsh climates and highly resistant to pests

When to Harvest Cannabis Ruderalis

Cannabis Ruderalis is ready for harvest about a month after it starts flowering. On average, the cannabis can be harvested within 70-110 days of planting the pure Ruderalis seeds.

Effects of Cannabis Ruderalis

Cannabis Ruderalis contains high levels of Cannabidiol (CBD) and is low on tetrahydrocannabidiol (THC). This makes it a popular go-to for medical marijuana patients who are looking to get the natural benefits of marijuana while avoiding the feeling of euphoria.

The high CBD content makes It a great choice for medicinal purposes. This high concentration has been shown to provide calming effects, which is why it is highly recommended for patients who suffer from insomnia, anxiety, and related conditions.

On the other hand, the low THC levels make cannabis Ruderalis an unpopular choice among recreational marijuana users who are more interested in the “high” or psychotropic effects of marijuana.

Is Cannabis Ruderalis Legal?

Short answer, yes. Cannabis Ruderalis is legal in areas where it is legal to grow and consume cannabis for both medicinal and recreational use. However, it is not a popular offering in many marijuana dispensaries. As stated, patients with anxiety and insomnia can benefit from the calming effect of the CBD-laden marijuana species. 

Top Pick for Breeders

Breeders have taken a keen interest in cannabis Ruderalis after understanding the characteristics of pure Ruderalis seeds. Breeders have crossed plants from the cannabis Ruderalis strain list with Indica and Sativa strains to produce hybrids with desirable characteristics.  Today, this type of cannabis is used almost exclusively for the purposes of breeding.

These hybrids, like the parent species, are auto-flowering. These hybrids also need around 9 weeks to mature and be ready for harvest. The crossing has produced hybrids with high levels of both CBD and THC.

Breeders have certainly taken the best that both worlds have to offer; developing medicinal and recreational auto-flowering strains that mature fast and have the right balance of cannabinoids to suit medicinal and recreational uses.
