Joan Senior daylily has creamy white flowers with lime green throats in early mid season. It may re-bloom. The 6-inch flowers stay open for at least 16 hours before closing and attract 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. The American Hemerocallis Society awarded Joan Senior the Lenington All-American Award 1990, Award of Merit , Honorable Mention, and Junior Citation
