Blue Paradise Tall Garden Phlox (Phlox paniculata 'Blue Paradise')

Blue Paradise Tall Garden Phlox brings saturated summer color and upright structure to borders right when many gardens need a fresh surge. Its tall, clump-forming habit adds height without feeling heavy, making it easy to layer among grasses, coneflowers, and other sun-loving perennials. The fragrant blooms draw butterflies and pollinators, adding movement and life through the heat of the season. If you want long-lasting color that reads from a distance, this is a reliable mid to late summer performer.

Distinctive Features

This tall garden phlox is known for rich lavender to violet-blue flower clusters that deepen in cooler light and bring a bold, cool-toned accent to warm-season plantings. Blooming from mid to late summer, it produces large, rounded heads of densely packed flowers that create strong visual impact and a classic garden look. The upright stems hold the blooms up nicely, helping the plant stay presentable in mixed borders. With good airflow and consistent moisture, it performs well and stays attractive through its extended bloom window.

Growing Conditions

• Soil: Moist, well-drained soil enriched with organic matter.
• Water: Water regularly, especially during dry spells, to support strong growth and steady blooming.
• USDA Zones: Zones 4 to 8.
• Spacing: Space about 18 to 24 inches apart to encourage airflow and reduce mildew pressure.

Ideal Uses
