Herbaceous plants are non-woody plants that die back to the ground at the end of their growing season. Examples of herbaceous plants include annuals, biennials, and perennials. Annuals complete their life cycle in one season and then die; biennials take two seasons to complete their life cycle and then die; and perennials live for more than two years and typically flower each year. Examples of herbaceous plants include roses, daisies, sunflowers, tulips, lilies, daffodils, poppies, irises, asters, chrysanthemums, petunias, marigolds and many more.
