Threadleaf Coreopsis ‘Zagreb’ | Plant Profile

Threadleaf Coreopsis ‘Zagreb’ (Coreopsis verticillata) are showy, clump-forming perennials. Small, yellow, daisy-like flowers bloom from May to June. Each flower has its own stem. Large numbers of flowers cover the top of the entire plant in spring. The flowers may bloom again in fall if the foliage is cut back after the spring bloom. Medium green grass-like foliage give the plant a fluffy appearance.

‘Zagreb’ prefers poor fertility, dry to medium moisture, well drained soil in full sun.

‘Zagrab’ are beautiful additions to wildflower gardens or naturalized areas. They are an effective option for rocky hillsides and areas with poor soil.


Threadleaf Coreopsis 'Zagreb' Characteristics

'Zagreb' are wildflowers that thrive in poor soils. They can be tolerant of heat, drought, and deer. Deadheading spent flowers can promote new fall blooms and prevent propagation via self seeding. Deadheading can be done by picking off individual flower heads or shearing the entire plant. Shearing will also help to keep the foliage tidy. They may spread by creeping roots that occasionally sprout a new plant.

There are few disease or insect issues that plague 'Zagreb'. Aster yellows and powdery mildew are uncommon. Slugs and snails may be occasional visitors. Rots may occur in poorly drained soils.
