Growing & Care

• Light: Thrives in full sun, where it produces the most abundant flowering. Tolerates partial shade, although reduced sunlight may result in fewer blooms.

• Soil: Adaptable to a variety of soil types and pH levels. Prefers average, well-draining soil and does not tolerate consistently wet or waterlogged conditions.

• Water: Water regularly while establishing. Once mature, it is moderately drought tolerant, although occasional watering during extended dry periods encourages continued flowering.

• Maintenance: Relatively low-maintenance and easy to grow. Remove spent flower spikes to encourage continued blooming and maintain a tidy appearance. Cut plants back to approximately 6–8 inches in late winter or early spring to encourage fresh, vigorous growth. Its stems can be somewhat brittle, so avoid planting in areas exposed to frequent physical contact.
