Common Name: Coreopsis-Threadleaf

One of the most loved perennials, C. 'Zagreb' is an excellent performer with bright golden-yellow flowers (a deeper yellow than 'Moonbeam') blooming from early through late summer. It forms an exceptionally bushy yet airy clump of fine, needle-like foliage on upright stems.

Coreopsis is one of the easiest perennials to maintain and is a good choice for beginners. It compliments nearly every other plant in the garden. The verticillata species is particularly long-lived, has a longer flowering time, and demonstrates better drought tolerance than others in the genus.
