Comment:

Phlox paniculata, commonly known as garden phlox, is native from New York to Iowa south to Georgia, Mississippi, and Arkansas. It has escaped gardens and naturalized into areas beyond its original native range. 

Garden phlox is a staple of the perennial border. Mixes well with other perennials and provides long summer bloom. Regardless of flower color, garden phlox is attractive to hummingbirds and is a good selection for inclusion in a bird garden.

Tall phlox is one of the best-loved garden flowers.  

Regions: Mountain, Piedmont, Coastal plains 

Seasons of Interest: 

  Leaf:                     Blooms:  Late summer            Nut/Fruit/Seed:  Fall

Wildlife Value:  This plant has little resistance to damage from deer.  It attracts hummingbirds, bees and butterflies.

Insects, Diseases, or Other Plant Problems: Phlox is not always an easy plant to grow well. Phlox bugs, powdery mildew, and root rot can be serious problems. Spider mites can also be a problem, particularly in hot, dry conditions. Taller stems may need staking.

Season:
Mid-summer to mid-fall
Height:
24-36 in.
Flower Color:
Magenta, pink, white, blue
Hardiness:
USDA Hardiness Zone 4-8
Foliage:
Garden phlox is an upright perennial that grows in a clump to 2-4' tall and to 2-3' wide on stiff stems clad with conspicuously veined, opposite, pointed, elliptic, deep green leaves (to 4-6" long). The leaves are lanceolate (shaped like the head of a lance). The veins branch off the center vein then curve toward the tip of the leaf near the edge and connect with the next vein, forming what appears to be a vein along the edge of the leaf.
Flower:
Garden phlox has fragrant, tubular, pink-purple to white florets (to 3/4” diameter) that are densely packed in large, tiered, domed terminal clusters (to 6-8") over a long July to September bloom period. Each individual floret has a long corolla tube and five flat petal-like lobes.
Habit:
Herbaceous perennial
Site:
Garden phlox grow in moderately fertile, medium moisture, well-drained soil in full sun to part shade. It does its best in full sun. It prefers rich, moist, organic soils. Also prefers moderate summer temperatures over the heat and humidity of the deep South. This plant needs good air circulation (space well and thin out stems as needed) to help combat potential powdery mildew problems. Intolerant of drought and needs to be watered in dry spells. Avoid overhead watering, however. It appreciates a summer mulch which helps keep the root zone cool. For winter, cut plants to the ground and remove from the garden plus clean up all plant areas in order to minimize possible powdery mildew infection for the following growing season. Remove faded flower panicles to prolong bloom period and to prevent unwanted self-seeding (cultivars generally do not come true from seed).
