The easiest way to define annual plants is that they complete their life cycle in one year. That is, the seeds sprout, the plants grow, then flower, set seed and die in one growing season. Perennial plants live for three or more years. There are tender perennials and woody perennials. Tender herbaceous perennials have tops which die down at the end of the growing season, but the roots remain alive and new shoots develop from the roots each season. Woody perennials may or may not lose their leaves during the winter months, but the stems and branches remain. New leaves and shoots are produced from the woody plant parts each spring. There's no sure way of knowing whether a plant is annual or perennial by just looking at them. When you're looking at plants in a garden center, the plants should be tagged with the information on whether they are annuals or perennials. Hope this answers your question!
