The short answer is no. Marigolds are annuals which means they are determined to complete their life cycle in one year and must be replaced annually. You may be able to save the seed from your marigold plants and then plant them outdoors in the spring after all danger of frost has passed or start the seeds indoors 4 to 6 weeks before the last frost date. These easy to grow, cheery, yellow bloomers are natives of Mexico and do not like cold weather, cold soil or cold wind. Sometimes saving seeds from flowers will produce offspring that do not look exactly like the parent plant. This happens because our modern hybrid plants do not always breed true. Experiment anyway - gardening is an adventure so dig in. Keep growing, Marianne Binetti
