Herbaceous plants are plants that have soft, non-woody stems. Examples of herbaceous plants include annuals, biennials, perennials, shrubs, and trees. Annuals are plants that complete their life cycle in one growing season and die after producing seeds. Biennials require two growing seasons to complete their life cycle and die after producing seeds. Perennials live for more than two growing seasons and produce flowers and fruits each year. Shrubs are woody plants that have multiple stems from the base of the plant. Trees are woody plants with a single trunk and multiple branches.
