Establishment
2-3 weeksYoung plants are small with a few heart-shaped leaves showing variegation
Keep soil consistently moist; provide afternoon shade; avoid transplant shock by not handling roughly
Vegetative Growth
4-8 weeksRapid spreading of rhizomes and development of dense foliage mat with prominent silver-edged leaves
Monitor spread; contain with barriers if needed; pinch back tips to encourage bushier growth; maintain consistent moisture
Flowering
6-8 weeks (summer to early fall)Small cone-shaped flower spikes appear above foliage, typically yellow and white in color
Flowering is secondary to foliage display; deadhead if desired to redirect energy to leaves; allow some flowers for pollinator interest
Peak Growth
Ongoing during growing seasonDense, lush foliage mat with maximum variegation display; plant reaches full mature size
Maintain consistent moisture; divide every 2-3 years to rejuvenate older plants; apply mulch in colder zones for winter protection
Dormancy/Winter
3-4 monthsFoliage dies back in colder zones; may persist as evergreen in zone 9-10
Cut back dead foliage; apply 2-3 inches of mulch in zones 5-7; reduce watering in mild winter regions
