Winner of the 2001 RHS Award of Garden Merit, this threadleaf coreopsis is just a little bit shorter than 'Moonbeam'. 'Zagreb' has bright yellow flowers that sit atop tall, erect, lacey, somwhat mound forming, delicate (threadleaf) looking, green foliage that has an airy appearance. The flowers are abundant and bloom continuously throughout the entire summer. Removal of the dead blossoms encourages longer blooming and healthier flowers. Truly a colorful sight. Great in rock gardens and gardens with poor soil. Makes a good cut flower.
Easily grown in dry to medium moisture, well-drained soils in full sun. Thrives in poor, sandy or rocky soils with good drainage, but grows easily in any average, well-drained soils. Tolerant of heat, humidity and drought. Deadheading of spent flower stalks will encourage additional bloom - shear in mid to late summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. 'Zagreb' can spread in the garden by rhizomes and self-seeding, particularly in moist, fertile soils.
