Like with most plants, there are male and female cannabis plants. Both produce pre-flowers, but only female and hermaphroditic plants fully blossom.
The flowering tip of the female plant, often called the bud, is the part harvested for consumption because it contains the highest concentration of cannabinoids, the chemical compound that produces the effects of cannabis.
Fan Leaf: While the cannabis leaf has become the symbol of cannabis, they only produce trace amounts of cannabinoids.
Cola: A cluster of buds on a female plant. They usually grow so closely together that they appear to be one large bud. This is where the highest concentration of cannabinoids is found. The topmost cluster of buds is called the main cola or apical bud.
Bracts: Small tear-shaped leaves that encapsulate the plant’s ovary (which contains its seeds). Some growers refer to the bract formation as the “seed pod.” Others refer to the bract formation as “sugar leaves” because of their white trichomes (see below).
Calyx: A collection of cells that form part of the perianth — a delicate, translucent veil that partially encloses the seeds.
Pistil: These are the female plant’s reproductive parts. The pistil’s most important feature is the coloured hairs (called stigmas) that emerge from the ovule and can be seen shooting out from the bracts and ovaries. The stigmas collect pollen from the male plant to produce seeds. While the colour of the stigmas can be visually appealing, these have little to no bearing on the effect.
