Coreopsis verticillata ‘Zagreb’, commonly known as Zagreb Threadleaf Tickseed, is a native cultivar of Threadleaf Tickseed valued for its compact habit, vivid golden-yellow flowers, and long bloom season. This tidy, clump-forming perennial typically grows 12 to 18 inches tall and wide, forming neat mounds that fit easily into borders, edging, and small garden spaces.

From early summer through fall, bright yellow, daisy-like flowers bloom continuously above fine, thread-like foliage. The airy texture of the leaves gives the plant a light, graceful appearance, while the steady flowering provides reliable color for months. Its compact size and clean form make it especially useful where structure and long-lasting bloom are both desired.

Zagreb Threadleaf Tickseed grows best in full sun and prefers well-drained soils. It thrives in hot, dry conditions and performs well in sandy or low-fertility soils, making it an excellent choice for low-maintenance and drought-tolerant landscapes.
