Moonbeam Coreopsis spp. was designated a native State Wildflower of Florida in 1991 in recognition of its beauty and frequent use in the state’s highway beautification plantings. Coreopsis verticiilata Moonbeam won the 1992 Plant of the Year Award from the Perennial Plant Association, and we can see why.
