Phlox paniculata 'Blue Paradise' (Garden Phlox)

Prized for its unique coloration, this everchanging phlox bears large clusters of fragrant flowers which open deep blue with a white eye and transition through shades of purple during the heat of the day. Its tall, sturdy stems, and dark green foliage display very good resistance to powdery mildew. This perennial grows 2-3 feet tall by 1-2 feet wide and blooms in the mid-late spring. It thrives in full sun.
