Coreopsis verticillata ‘Zagreb’

6 Photos


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. While the exceptionally dense habit can encourage powdery mildew to develop, it is hardly noticeable on such finely dissected leaves. C. verticillata ‘Zagreb’ spreads rhizomatously by approximately 2’ over three years.
