Blue Paradise Garden Phlox features bold fragrant conical lilac purple star-shaped flowers with red eyes at the ends of the stems from early summer to early fall. The flowers are excellent for cutting. Its narrow leaves remain dark green in colour throughout the season. Blue Paradise Garden Phlox is an herbaceous perennial with an upright spreading habit of growth. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.
