Phlox paniculata L.
Fall Phlox, Perennial Phlox
Polemoniaceae (Phlox Family)
USDA Symbol: phpa9
USDA Native Status: L48 (N), CAN (I)
Fall Phlox is a showy clump-former, reaching a height of 3-6 ft. The pink, lavender, or rarely white flowers are borne in a 4-8 in. wide, terminal pyramidal cluster. The stout, smooth stem holds narrow leaves 4-7 in. long.
If found in the wilds beyond its natural range, this species has probably escaped from cultivation. Many color forms are found in gardens. The very similar Large-leaved Phlox (P. amplifolia) has a hairy stem, only 6-15 leaf pairs below the flower cluster, and a hairless corolla tube; it is found in the southern Appalachian Mountains.
