Answer: You're question is really quite common, so don't feel bad about asking it. Annual plants are those that grow, bloom, and set seed all in one growing season. Commonly grown annuals include alyssum, marigolds and petunias. Annuals are temporary members of the landscape and need to be replaced each spring. Perennial plants are those that live for more than two years. Some perennials are tender and their foliage dies down after the first frost of the season, but their roots remain alive. These plants will produce new foliage and flowers the following spring. Good examples are campanula and chrysanthemums. Some perennials retain their foliage during the winter months - Shasta Daisies and Japanese Anenome, for instance. Hope this information helps clarify things for you.
