Fragrant Treasure daylily has 4½-inch light yellow flowers with a yellow green throat. It blooms early in the season and may re-bloom. As the name suggests, the flowers are very fragrant and attractive to butterflies and hummingbirds. 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.
