Annuals are plants that have a life cycle of one growing season and then die off. These plants typically bloom from late spring or summer until the first frost of winter. Annuals need to be replanted each year in order to continue blooming. Some popular annuals include petunias, zinnias, and marigolds.
Perennials are plants that typically live for two or more years. Perennials come back year after year as long as they are given the proper care and environment. These plants usually bloom in the spring or summer and may die back in the winter. Popular perennials include hostas, daylilies, and daisies.
