Many plants offer a pleasant fragrance, adding another layer of enjoyment near patios and walkways. As the clump matures, it becomes a dependable seasonal highlight with strong stems and a clean, leafy habit.

Growing Conditions

• Sun: Full sun to part sun, with at least 6 hours of sun for best flowering.
• Soil: Rich, well-drained soil is ideal, with compost added to improve structure and drainage.
• Water: Water regularly during establishment, then provide consistent moisture during dry stretches, avoiding soggy soil.
• USDA Zones: 3 to 8.

Low Maintenance Care

• Watering: Water deeply during dry spells, especially in spring as buds form and after flowering as roots store energy.
• Staking: Support heavy blooms with rings or stakes if stems lean after rain.
• Feeding: Top-dress with compost in spring and avoid heavy nitrogen that can reduce flowering.
