Tall Garden Phlox (Phlox paniculata)

Tall garden phlox is an upright, clump-forming perennial with flowering stems that bring color to summer and fall borders. Phlox paniculata varies among cultivars, so flower color, mature size, and disease resistance differ; this species profile describes the general garden plant. ## Growing Conditions Garden phlox commonly reaches 2–4 feet tall and prefers sun to partial shade with moist, fertile, well-drained soil. It attracts hummingbirds and mixes well with other perennials. Good spacing and air circulation help reduce powdery mildew; water at the soil rather than over the foliage.

Remove faded flower heads to prolong bloom and limit seedlings, since cultivars do not come true from seed. ## Maintenance After flowering, remove old stems and clear them from the garden to reduce carryover of powdery mildew. Taller stems may need staking.
