Coreopsis ‘Show Stopper’

7 Photos


Coreopsis ‘Show Stopper’ stands out in our trial for its bright, fuchsia-colored flowers. This cultivar is also one of the most floriferous and longest-blooming selections that we evaluated. Unfortunately, problems with floppiness and powdery mildew were observed each year. But, if tightly planted near supportive neighbors, ‘Show Stopper’ might not flop as it did in our garden. The floral display is impressive enough that many people may be willing to overlook these faults.
