Perennial flowers are presented in any garden for three reasons. First, the perennial flowers do not require a lot of maintenance and they tend to be hardy and drought tolerant, so perennials do not need a lot of help from you to survive. Second, you don not need to replant every year the perennial plants, because they come back season after season, so no replanting are required. Third, because of their resilience and consistency, perennials provide the foundation around which short-lived annuals can be planted.
The perennial flowers grow back each year from roots that go dormant in the soil in the winter. There are perennials for every location in your garden including full sun, partially shaded, or fully shaded spots, and you can grow flowers in a variety of colors for various bloom seasons.
