Big Time Happy daylily has moderate sized  4” soft yellow blooms with a green throat. The petals have ruffled edges. 'Big Time Happy'is one of only a very few truly everblooming daylilies that are available in northern areas. It blooms and reblooms continuously from mid spring until frost, an unusually long bloom period for a daylily. Although each flower lasts only one day, there are multiple buds on each stalk and there are several stalks on each plant. The buds open in series, so a single plant will continue to bloom for an extended period. It is easy to grow and does well in either full sun or part shade.
