Common Name garden phlox, summer phlox, fall phlox, tall phlox
Genus   Phlox
Species  P. paniculata 
Family  Polemoniaceae
Life Cycle   Hardy Perennial 
Tray Size   32
Plug Care  Pot up or plant soon after arrival.
Netting / Staking  Not necessary but 1-2 layers of netting could be   beneficial for taller varieties in windy zones. 
Temperature Range  Hardiness zones 4-8
Spacing  12-24"
Soil Preference  Fertile, moist but well draining soil. Amend soil with   compost and granular fertilizer before planting for best   results. 
Day Length  Long day plants - flower in the summer. Plant in full sun. 
Pinching  Do not pinch 
When to Plant  Plant plugs in the spring upon arrival. They may arrive   looking dead, or with no top growth at all - this is   because they are still dormant and have not yet woken   up. If new growth has started, keep from freezing. 
Harvesting  Expect a few flowers the first season after planting, but   the main harvest will come 2-3 years after planting   when the plants have matured. Harvest stems when a   few of the flowers have opened and the remaining buds   will open in the vase. After harvesting, cut the remaining   stem down to the ground and the plant will resprout and   reflower in the same year, extending your harvest. 
Post Harvest Care  Place cut stems immediately into cool water. Can be   stored in the cooler for a short time - best to use a floral   conditioner. 
Diseases / Insects  Perennial phlox are notorious for getting powdery   mildew in some areas, especially zones with warm, wet,   humid summers. All varieties offered by Farmer Bailey   have some level of resistance bred into them. Avoid   overhead watering to keep the foliage dry. 
Bailey's Notes

 "The Fashionably Early series is one of my favorites, and   it does indeed bloom early, is disease free and will give   2-3 flushes of blooms per season." 

 As tall phlox becomes overcrowded, flower production   will decrease. You may need to divide them every 3-4   years.
