- Light
- Full sun (6+ hours per day); can tolerate very light shade but may become floppy.
- Water
- Low to medium. Once established, it is quite drought-tolerant. Water weekly during extreme heat; over-watering can lead to root rot.
- Growth
- Herbaceous perennial; upright, mounding habit. Typically grows 12-36 inches tall and 12-24 inches wide at a moderate to fast rate.
Care instructions
Plant in a sunny location with well-drained soil. Regular deadheading of spent flower spikes will encourage re-blooming throughout the summer. Fertilize lightly in spring.
