Trial Garden

Phlox paniculata ‘Eva Cullum’

6 Photos


At the start of the trial, Phlox paniculata ‘Eva Cullum’ was a vigorous and lush plant. However, it proved to be very sensitive to powdery mildew and dropped significant amounts of foliage each season. By the third year, the plants had deteriorated so much from successive defoliations that they were almost too weak to flower.
