Growing cheerful and colorful blooms is so easy with daylilies. These low-maintenance perennials are available in a wide selection of colors and are perfect for growing in perennial beds, mass plantings and along fence rows. Their grasslike foliage stays attractive throughout the growing season. Unlike some perennial flowers, daylilies can handle many harsh conditions including city environments, dry soils and winter salt. These popular, versatile perennials perform best when they receive full sun to partial shade. Most daylily varieties are suitable for gardens in zones 3-8. While some daylilies bloom once a year, others are reblooming daylilies. To enjoy daylily flowers for weeks and weeks, choose early, mid-season and late-season bloomers.
