Coreopsis is derived from Greek corio-(bug)and -opsis (likeness) components with reference to the appearance of the seed.(www.plantlives.com). Has won Europe's Fleuroselect Gold Medal and All American Selection awards.
To me (zone #5) the grandiflora Coreopsis are much harder to keep alive than the thread leaf (C. verticillata)cultivars. Well drained soil to prevent rot is a must.
