Coreopsis palustris ‘Summer Sunshine’

4 Photos


Coreopsis palustris ‘Summer Sunshine’ was a consistently impressive cultivar year after year. ‘Summer Sunshine’ is one of the few coreopsis that blooms in the fall – its golden flowers with dark cones last about six weeks during September and October. ‘Summer Sunshine’ not only has an amazing fall floral display, but the plant has a dense and sturdy habit as well as disease resistant foliage. Because it is such a late bloomer, ‘Summer Sunshine’ serves as an important late-season food source for pollinators.  It should be noted that we trialed two versions of Coreopsis palustris, and ‘Summer Sunshine’ was a far superior clone in terms of habit and disease resistance.
