Tomatoes are treated as annuals, but I have some tomato plants three years old that produce. What flowering plants are treated as annuals but are perenials that have lots and lots of flowers throughout the spring summer and fall (like petunias bloom)?

Annual plants grow, flower, set seeds and die. No matter how carefully to treat them, they will die at the end of the season. Tender perennials, such as tomato plants, will die when temperatures get cold but can be coaxed to live for several years in a frost free environment. When you are looking at plants, check the tags. The tags should give you the hardiness information. If they are hardy above about 40F, they should make it through your normal winters and can be treated as perennials. There are too many potential candidates to list here so you'll need to do a web search on each of the plants that interest you - or you can simply experiment with your favorite plants. Best wishes with your garden!
