Features of Threadleaf Coreopsis


Yellow flowers on rounded plants with fine, feathery foliage. Excellent plant for almost continuous summer flowering. Long living perennial. Can spread by underground rhizomes. Drought tolerant.


  • Prefers well-drained soils in a sun location.
  • Cut back after their first flush of flowers for an autumn flush of flowers.
  • Don't over-fertilize as it leads to soft, floppy plants.
