Chicago Orchid daylily has lovely lavender flowers measuring 4.75 inches in diameter. It blooms early to mid season and is 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. It is easy to grow and does well in full sun to part shade.
