What is the difference between annual flowers and perennial flowers? Plants can be classified as either annual, biennial, or perennial. Annual plants live for only one growing season, during which they produce seeds, then die. Familiar annual plants include impatiens, zinnias, and sunflowers. Biennial plants, such as some types of foxglove, live for two growing seasons before setting seed and dying. The term perennial is reserved for plants that live for more than two years. Trees and shrubs live for more than two years. Are they perennials?
