Herbaceous flowering plants

HERBACEOUS FLOWERING PLANTS TYPICALLY HAVE GREEN, NON-WOODY STEMS, and tend to be relatively
short-lived. Many herbaceous plants live for only one or two years. Annuals (e.g., sweet peas) grow from
seed, produce flowers and then seeds, and die within a single year. Biennials
(e.g., carrots) have a two-year life cycle. In the first year, seeds grow into plants, Young plant
which produce leaves and store food in underground storage organs; the stems forming
and foliage then die back in winter. In the second year, new stems grow from
the storage organs, produce leaves, flowers, and seeds, and then die. Some
