Phlox paniculata ‘Delta Snow’

Summary

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. The weight of all the flowers did cause the stems to slightly angle outward; however, it wasn’t severe enough to reduce the plants overall appearance.
