Coreopsis verticillata ‘Moonbeam’ (threadleaf coreopsis) is a long-blooming selection.
1992 Perennial Plant Association Plant of the Year.
A classic perennial, 'Moonbeam' is an excellent performer with bright lemon-yellow flowers produced in profusion from early through late summer. The airy clumps of fine, needle-like foliage on upright stems add a nice fine texture element to the landscape. Photo courtesy of Walters Gardens
