Perennial plants will live for three or more years. Many perennials require several growing seasons to flower and produce seed. Perennial plant seed can also be re-sewn in the landscape. Some key things to know are: stratification and vernalization. Stratification is the cold requirement that some seeds may require before they will germinate, vernalization is the overwinter cold requirement that existing plants must experience before they will make seed heads.

Ethnobotany is the study of a region's plants and their practical uses through the traditional knowledge of a local culture and people. An ethnobotanist thus strives to document the local customs involving the practical uses of local flora for many aspects of life, such as plants as medicines, foods, intoxicants and clothing. Ethnobotany is investigating plants used by societies in various parts of the world.
