Coreopsis (pronounced kor-ee-OP-sis) is a group of native perennials with bright, daisy-like flowers and a clumping habit. Most Coreopsis have yellow flowers, but hybridizers have introduced new cultivars with flowers of burgundy, rust, red, or bi-colors. ‘Moonbeam’ and ‘Zagreb’ are two of the best yellows. Coreopsis verticillata has a narrow (“threadleaf”) foliage.
Locate plants in full sun or mostly sun, in well-drained neutral or acidic soil, zones 3-9. Plants attain heights of two to three feet. Individual Coreopsis flowers are small but the plant will cover itself, putting on a show. The size of the flowers make deadheading tedious. Once most flowers have faded, use clippers or hedge-trimmer to decapitate the spent blooms and their stems. Plants will regenerate and rebloom.
Coreopsis tolerates heat and humidity. They attract pollinators but not deer. Their airy appearance makes them a good choice for a cottage garden, a native garden, or children’s garden.
