Variety - A plant sporting different properties, or traits — like varying flower colours — than another of the same species.

Cultivar - A plant variety cultivated for a desirable characteristic present in that variety.

Cultivation - Intentionally planting/growing something.

Hybrid - The result of cross pollinating two different plant varieties and growing the seed collected from the resulting offspring

Genus - A group of species that are closely related through a common parent (at some point in their evolution), but can’t readily interbreed. Between family and species.

Species - A group of plants that share common characteristics and are capable of interbreeding. Comes after genus and before variety or cultivar.

Traits - A feature or characteristic of a plant. Anything that defines a specific plant can be considered a trait.

Open pollination - A naturally occurring pollination, by insect, bird, wind or humans. Due to the open nature of the flow of pollen, open-pollinated plants are more genetically diverse

Landrace - A locally adapted, traditional variety of a plant that has developed over time, through adaptation to its natural and cultural environment. Often open pollinated, and thus more genetically diverse and conventional cultivars.

Heirloom - An open-pollinated cultivar that was commonly grown historically. Not used in modern industrial agriculture.
