Beautiful garden phlox without a hint of powdery mildew is the holy grail of phlox variety breeding. We seem to be as close as we can get to this prize, for it is rated "exceptionally clean" in multiyear trials. Besides the pristine foliage, the ample blush pink flower clusters swirling open from rosy buds are alive with the many species of butterflies, including yellow and black Swallowtails, plus bees and hummingbirds.
