Distinctive Features

Opalescence produces light pink flowers with dark pink eyes, arranged in defined panicles that sit neatly above dark green foliage. The contrast between the delicate petals and deeper centers adds depth up close while still reading as a calm, cohesive color from a distance. Blooming from mid to late summer, it extends the season of color and blends smoothly with both bright and pastel palettes. The upright stems create a clean vertical accent that keeps borders looking structured and intentional.

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 steady 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.
