text: Unlike annual plants (zinnias, marigolds, radish) which complete their life cycle in one growing season and biennials (Sweet William, hollyhocks, onions) which need two growing seasons to mature and go to seed, perennials may go to seed every year and may even die back to the ground at times, but their root systems are very much alive and the plants will continue growing when conditions are right.
