'Everlasting Light' daylily has icy yellow flowers with a green throat. The blooms are quite large, measuring 6½ inches and appear early in the season. As the name implies, it is green all year long in milder climates. Although each flower lasts only one day, there are multiple buds on each stalk and several stalks on each plant. The buds open in series, so a single plant will continue to bloom for 2 weeks or more. The plant is easy to grow and does well in full sun to part shade.
