Perennials are plants that live for at least three growing seasons, but many perennials will come back year after year almost indefinitely. These landscape plants are important as you need a few plants in your landscape you can rely on to come back year after year to beautify your landscape. Be sure to select varieties that are suited to your particular soils and climate to ensure the best growth and blooms each year.
