Know before you buy
While both are Threadleaf Coreopsis, 'Zagreb' produces a more intense, deeper golden-yellow bloom compared to the softer, pale yellow flowers of 'Moonbeam'. It also tends to maintain a slightly more compact, bushy habit.
Yes, Coreopsis verticillata 'Zagreb' is considered deer-resistant. While no plant is entirely deer-proof, its fine, needle-like foliage is generally unappealing to deer compared to other garden favorites.
Absolutely. Its mounding growth habit and drought tolerance make it an excellent choice for containers, provided the pot has adequate drainage and receives full sun throughout the day.
This is a low-maintenance perennial. You can shear the plant back by about one-third after its initial summer bloom to encourage a fresh flush of flowers and keep the mound looking neat.
Coreopsis 'Zagreb' is hardy in zones 4 through 9. This means it is well-equipped to handle cold winters as far north as zone 4, provided it is planted in well-draining soil.
Since 'Zagreb' has a mature spread of about 18 inches, you should space them roughly 15 to 18 inches apart. This allows enough room for the airy clumps to touch without overcrowding.
