Establishment
4-8 weeksYoung transplants with small rosettes of bronze foliage beginning to develop. Leaves are smaller and less colored than mature plants.
Water regularly to keep soil moist. Apply 1-2 inches of mulch around the base. Avoid planting too deep, as this can cause crown rot. Protect from extreme heat during the first season.
Foliage Development
2-3 monthsThe plant forms a substantial rosette of deeply colored bronze to mahogany leaves with metallic undertones. Foliage becomes fuller and more vibrant over several months.
Maintain consistent moisture. Remove any damaged or yellowing leaves. Provide afternoon shade in hot climates. Monitor for slugs and snails.
Flowering
4-6 weeks (spring to early summer)Delicate coral to salmon-pink flower spikes emerge from the center of the foliage rosette. Flowers are small, bell-shaped, and densely arranged on upright stems.
Deadhead spent flowers to encourage continued blooming. Water at the base to keep foliage dry. These flowers attract hummingbirds and pollinators.
Post-Flowering
6-8 months until dormancyFlowers fade and foliage remains as the main ornamental feature. The plant prepares for dormancy in colder climates or continues to provide color year-round.
Continue deadheading if desired for tidiness. Reduce watering gradually as temperatures cool. Leave foliage intact over winter for frost protection.
Winter Dormancy
3-4 monthsIn colder zones, foliage may become darker or take on purple tones. The plant becomes semi-dormant but retains its attractive leaf color in most climates.
Do not cut back foliage; leave it to protect the crown from freeze-thaw cycles. Reduce watering to minimal amounts. Resume normal care in spring.
