Growing and Maintenance Tips
- Light: Requires full sun for optimal growth and flowering.
- Soil: It prefers well-draining soil and adapts to various types, including sandy or clay soils. An ideal pH is slightly acidic to neutral.
- Watering: Drought-tolerant once established, but regular watering is needed during dry spells.
- Temperature: Hardy in USDA zones 7–10, it can withstand heat and occasional frost.
- Fertilizer: Apply a balanced fertilizer in spring and summer to encourage blooms, though it thrives in average soil without additional feeding.
- Pruning: Prune in mid-summer to encourage thicker growth and more flowers in the fall. Cut back to the ground after the first frost and mulch for winter protection.
- Pest and Disease Resistance: It is virtually pest-free and resistant to deer and goats. Avoid overwatering to prevent fungal issues.
