Abstract
A new cultivar of hybrid Coreopsis named ‘Daybreak’ that is characterized by its compact plant habit reaching about 30 cm in height and 50 cm in spread, its prolific blooming habit from late June until frost in Connecticut, its large inflorescences with ray florets that are golden yellow in color with very large red eye zones that expand to nearly cover the entire ray floret in cooler temperatures, its near sterility when grown under typical garden conditions without the requirement for deadheading of spent blooms for continuous bloom and its ability to be readily propagated by stem cuttings throughout the growing season.
