Backlight Tall Garden Phlox

Backlight Tall Garden Phlox (Phlox paniculata 'Backlight')

Backlight Tall Garden Phlox brings crisp, bright summer bloom to mixed borders when many gardens need a clean lift. Its upright clumps add height without taking over, so it layers easily between shrubs and mid-height perennials. The fragrant flowers draw butterflies and other pollinators, keeping the garden active through the heat of the season. If you want dependable blooms that look fresh from a distance, this is a strong mid to late summer performer.

Distinctive Features

Backlight Tall Garden Phlox produces pure white flowers in well-defined panicles held above dark green foliage for a clear, high-contrast look. Blooming from mid to late summer, it extends the color season and pairs naturally with ornamental grasses and other late-blooming perennials. The upright stems create a clean vertical line, so the plant adds structure without a bulky footprint. With good airflow, consistent moisture, and sun, it holds up well and stays attractive through its long bloom window.

Growing Conditions

• Sun: Full sun to partial sun, with best flowering in full sun.
• Soil: Moist, well-drained soil enriched with organic matter.
• Water: Water regularly, especially during dry spells, to support strong growth and sustained flowering.
• USDA Zones: Zones 4 to 8.
• Spacing: Space about 18 to 24 inches apart to encourage airflow and reduce mildew pressure.
