Herbaceous plants are a type of plant that do not have woody stems above ground. Examples of herbaceous plants include annuals, biennials, and perennials. Annuals complete their life cycle in one year, biennials take two years to complete their life cycle, and perennials live for several years. Common examples of herbaceous plants include many vegetables, such as tomatoes, peppers, and squash; flowers such as roses, daisies, and tulips; and herbs such as basil, oregano, and mint.
