Garden Phlox 'Luminary™ Sunset Coral' (Phlox paniculata 'Luminary™ Sunset Coral') is a standout summer bloomer that fills borders with clustered, coral-pink flowers and a pleasant fragrance. You will get the best display with full sun to part shade and consistently moist, fertile, well-drained soil.
Plan for a mature height of about 24-36 inches, and allow space for good air movement between plants. Good airflow and avoiding overhead watering help reduce powdery mildew pressure. Water during dry spells, especially in summer heat, and use mulch to keep roots cool and soil moisture more even.
For a longer season of color, remove spent flower heads as blooms fade. This tidy step can encourage continued flowering and helps keep the plant looking fresh. In spring, cut back old stems and clean up the crown area. In a mixed perennial planting, this phlox pairs well with other sun to part-shade favorites and is an easy way to add pollinator activity, especially butterflies, through the heart of summer.
