Coreopsis
Coreopsis grandiflora

Coreopsis is a mainstay of the summer garden. It grows from 1-2 feet tall producing flowers from May through August if the spent flowers are removed regularly. Deadheading to encourage rebloom is best done so the whole flower stalk is removed and not just the flower head. Coreopsis grows very well in full sun in a well-drained soil. It is tolerant of dry soil. If grown in moist, fertile soil, Coreopsis has a tendency to open up resulting in plants that are not as attractive. Cultivars to look for include 'Early Sunrise', 'Sunray' and 'Goldfink'.
