What’s the difference between annuals and perennials?

Annuals grow for one season, and then die when the weather gets cold. Perennials grow for multiple seasons, and regrow every spring after being in dormancy during the winter. Examples of popular annuals in Pennsylvania are pansies, snapdragons, petunias, geraniums, salvia, California poppy, violas, and many more. Some perrenial examples are daffodils, phlox, peonies, purple coneflower, daylilies, black-eyed susan, Virginia bluebells, coral bells, hostas, and more.
