Coreopsis verticillata ‘Zagreb’
Description
One of the most loved perennials, ‘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.Coreopsis is native to North America. Therefore, it is easy to grow, thriving in any well-drained soil and full sun. Once established, it is rather drought tolerant. It can be propagated either by seed or by division every few years in spring or fall.Photo courtesy of Walters Gardens, Inc.For reference only:
