Daylilies (Hemerocallis) are the plants every gardener dreams of. Beautiful and rugged, they provide glorious blossoms in a wide range of colors, and a long season of bloom (though individual flowers last but a day). They can be used as a carefree ground cover, and are ideal for lining pathways and borders. Some newer varieties produce many flower buds and stay in bloom for a longer period. Many Daylilies have more than one bloom cycle, and benefit from deadheading and additional fertilizer in midsummer.
