Perennial flowers are those that come back season after season without replanting. Flowering plants that are perennial can really make your garden a lower-maintenance prospect, eliminating the need to replant year to year, while maintaining a lovely aesthetic. Perennials make great choices for any garden whether it is a shade garden, container garden or landscaping.
