Establishment
4-6 weeksYoung plants begin with green foliage, slowly developing red tipping on leaf blades as they acclimate to the landscape.
Water regularly to establish deep root system. Protect from extreme heat during first summer. Mulch lightly around base.
Vegetative Growth
6-8 weeksPlant develops fuller clump structure with increasing red coloration on upper leaves and tips. New shoots emerge from crown.
Maintain consistent moisture during growing season. Begin to reduce supplemental watering as roots establish. Remove any dead or damaged foliage.
Color Development
8-12 weeksRed coloring intensifies dramatically, especially in cooler months and with increased sun exposure. Foliage can display brilliant crimson to deep burgundy tones.
Maximize sunlight exposure for peak color. Avoid over-fertilizing, which promotes green growth at expense of color. Monitor for stress indicators.
Maturity
Ongoing through growing seasonFully established plant maintains compact clumping form. May produce small, whitish flower spikes in late summer to fall (though rarely flowers in cooler zones).
Fertilize lightly in spring with balanced fertilizer. Continue moderate watering schedule. Deadhead flower spikes if desired.
Winter Dormancy
October-MarchFoliage dies back and turns straw-colored in fall/winter. Plant goes dormant and requires minimal care.
Cut back dead foliage to 2-3 inches in late winter (February-March) before new growth emerges. Leave dormant plant in place for winter interest if desired.
