We talked to Tony Maiello, manager of the Metropolitan Plant and Flower Exchange in New Jersey to find easy and affordable flowers for a garden that is sure to leave your neighbors green with envy. For novice gardeners, perennial flowers are a great place to start— they tend to bloom over the spring and summer, die over fall and return again the next spring. To save money, gardeners can pack the majority of their gardens with perennials with a couple annuals dispersed throughout. Annual flowers tend to die in a year or season—which can add up if you have to buy new flowers each season.
