Coreopsis verticillata 'Zagreb' (Threadleaf Coreopsis)

Threadleaf Coreopsis 'Zagreb', Whorled Coreopsis 'Zagreb', Coreopsis 'Zagreb', Tickseed 'Zagreb'


An excellent performer, award-winner Coreopsis verticillata 'Zagreb' (Threadleaf Coreopsis) is a compact perennial forming a gorgeous mound of finely divided leaves. Blooming continuously from early to late summer, it gets in covered with a profusion of bright golden-yellow blossoms. The airy clumps of fine, threadlike foliage on upright stems add a lovely delicate texture element to the landscape. Long-lived, this is one of the best and toughest performers suitable for a sunny position in the garden.

  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society
  • Grows up to 15 in. tall (37 cm) and 12-15 in. wide (30-37 cm). Zagreb' can spread in the garden by rhizomes and self-seeding, particularly in moist fertile soils.
  • Prefers full sun but tolerates partial shade (specifically in hot summer areas) and enjoys dry to medium moisture, well-drained soils. Thrives in poor, sandy or rocky soils and is drought tolerant
  • Easy to grow, relatively pest and disease free, this Coreopsis is a favorite of bees and butterflies but is ignored by deer.
  • Very versatile, it is a welcomed addition to borders, naturalized areas, cottage gardens and does great in containers. Effective as an accent plant and spectacular in mass plantings.
  • Deadheading of spent flowers will promote new blooms, although this can be tedious. Midsummer shearing (after the first flush of flowers) should help tidy up the plant and promote a fall rebloom.
