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.
