Coreopsis 'Berry Chiffon'
This floriferous new Coreopsis forms a full, sturdy, upright clump of dark green, threadleaf foliage topped with white flowers with a vibrant raspberry red eye. They first appear in midsummer and continue through early fall without deadheading, with the raspberry color expanding to cover most of the flower’s petal surface in cooler temperatures. ‘Berry Chiffon’ is sterile, so it won’t seed around the garden and its foliage is very resistant to powdery mildew so you won’t need to spray it with anything to keep it looking great all season long. Gardeners have loved threadleaf Coreopsis verticillata since the invention of ‘Moonbeam’ many moons ago. But those who garden in cooler climates have struggled to keep them from going dormant early in the season because that species is heat loving and not particularly cold tolerant.
