According to the Royal Botanical Gardens database, there are 170 species grouped in nine to fifteen genera, including three well-known genera Cannabis (hemp), Humulus (hops) and Celtis (hackberries). Celtis is by far the largest genus, counting 100 species.

Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Rosales
Family: Cannabaceae


Cannabis is a dioecious, annual herb


The term "ruderal" was originally used in the former Soviet Union to describe populations of hemp that had escaped cultivation and adapted to the surrounding region. Plants of this type are widespread throughout central and eastern Europe, including Lithuania, Belarus, Latvia, and Estonia. Similar populations can be found in most of the areas where hemp cultivation was once prevalent. The most notable region in North America is the midwest, though populations occur sporadically throughout the United States and Canada. These plants have escaped from cultivation more recently, and often grow larger than the ruderal plants in Europe.

It has several times been proposed that this type of Cannabis be recognized as a distinct species, called C. ruderalis

Wide-leafed "indica" drug strains are traditionally cultivated in northwest India, Afghanistan, and Pakistan for the production of hashish, and may have originated in the Hindu-Kush or Tian Shan mountain range. Due to the often harsh and variable climate of those regions, these strains and landraces are better suited for cultivation in temperate climates. Plants of this type are relatively short, conical, and densely branched, having characteristcally wide leaflets, and tend to produce a lower ratio of THC to CBD than the narrow-leafed drug strains Although many commercially available varieties are genetically fixed to produce relatively high levels of THC and low levels of CBD (which is not psychoactive),some users report more of a "stoned" and less of a "high" effect from these varieties compared to the narrow-leafed strains. Differences in the terpenoid content of the essential oil may account for some of these differences

includes wild or feral plants, mostly confined to the Indian subcontinent and other regions where Cannabis is grown for drug use and has escaped from cultivation. Individual plants may have low, similar, or high levels of THC relative to CBD. Plants with relatively high levels of Δ9-tetrahydrocannabidivarin (THCV) and/or cannabidivarin (CBDV) are also common in this group. Compared with wild or feral plants of var. spontanea, plants of this taxon are often taller and more branched. The achenes are usually very small. The inflorescenses of pistillate plants are often elongated, and the fruits (achenes) drop off the plants as they mature.

Cannabis reproduces sexually. The flowers of the female plant are arranged in racemes and can produce hundreds of seeds. Males plants shed their pollen and die several weeks prior to seed ripening on the female plants. Although genetic factors dispose a plant to become male or female, environmental factors including the diurnal light cycle can alter sexual expression. Naturally occurring monoecious plants, with both male and female parts, are either sterile or fertile but artificially induced "hermaphrodites" (a commonly used misnomer) can have fully functional reproductive organs. "Feminized" seed sold by many commercial seed suppliers are derived from artificially "hermaphrodytic" females that lack the male gene, or by treating the seeds with hormones or silver thiosulfate.

A Cannabis plant in the vegetative growth phase of its life cycle can thrive under twenty-four hour daylight conditions, although some growers advocate a small "rest" period to avoid "over-stressing" the plant. Flowering usually occurs when darkness exceeds eleven hours per day. The flowering cycle can last anywhere between four to twelve weeks, depending on the strain and environmental conditions.

In soil, the optimum pH for the plant is 6.5 to 7.2. In hydroponic growing, the nutrient solution is best at 5.2 to 5.8, making Cannabis well-suited to hydroponics because this pH range is hostile to most bacteria and fungi.
