TOP PERFORMERS Phlox paniculata 'Delta Snow' «««« Phlox paniculata 'Delta Snow' hails from Mississippi where it originated as an old pass-along plant, a term used for plants that were loved so much that neighbors freely shared them with one another. Part of the longstanding appeal of this cultivar is its exceptional resistance to powdery mildew. In fact 'Delta Snow' has been recognized as one of the most disease resistant cultivars in several trial programs throughout the United States. Although its claim to fame is disease resistance, 'Delta Snow' also produces an incredible number of large inflorescences with white flowers accentuated by a bright lavender center. Phlox × arendsii 'Babyface' «««« Phlox × arendsii 'Babyface' is thought to be a hybrid of Phlox paniculata and Phlox divaricata, which is typically denoted as P. × arendsii. Although this cultivar may have been derived from such a hybrid, it looks and behaves like Phlox paniculata. 'Babyface' does develop some powdery mildew, and frequently drops its lower leaves as a result. However, all of that can easily be forgiven thanks to its first-class floral display. The broadly pyramidal inflorescences are made up of small pink flowers with a darker pink center. The buds are also extremely attractive thanks to the dark calyx found at the base of each bud. This provides as much as two additional weeks of interest prior to the flowers opening. 'Babyface' also has a relatively late floral display which peaks in early August, a few weeks later than most cultivars. 4
