Annuals have one growing season and need to be replanted each spring. They include most vegetables like cucumbers and tomatoes, and flowers like Marigolds or Sunflowers.
Perennials are permanent residents in your garden and will return year after year.
Some examples include Asparagus and Strawberries. Plan ahead, because many perennials will spread year after year, but will also take a few years to establish roots and produce fruit.
