"Coreopsis verticillata ‘Zagreb’ is the epitome of uniformity and precision. This cultivar’s habit is shorter than other selections of C. verticillata, reaching only about 20” tall, and beginning in June, the plant is covered with bright yellow flowers. Because ‘Zagreb’ has such a uniform habit, all of the flowers are held at the exact same height, creating a floating carpet of gold. The fine-textured foliage gives the plant a very soft, attractive look, even when not in bloom." -- Mt. Cuba Center
"Easily grown in dry to medium moisture, well-drained soil in full sun. Thrives in poor, sandy or rocky soils with good drainage. Tolerant of heat, humidity and drought. Prompt deadheading of spent flower stalks can be tedious for a large planting, but does tend to encourage additional bloom and prevent any unwanted self-seeding. Plants may be sheared in mid to late summer to promote a fall rebloom and to remove any sprawling or unkempt foliage." -- Missouri Botanical Garden
Coreopsis verticillata 'Zagreb' won the Royal Horticultural Society Award of Garden Merit in 2001.
