Growth Stages

1

Establishment

3-6 months

Young plant is small with modest foliage; developing root system

Keep consistently moist during first growing season. Mulch around base. Avoid planting too deep.

2

Vegetative Growth

6-18 months

Plant expands in size, golden-yellow centers become more prominent, foliage increases in density

Water regularly during dry spells. Light, balanced fertilizer if desired. Remove any dead foliage in early spring.

3

Mature Clump

Ongoing, typically 2-3 years to reach full maturity

Plant reaches full size (12-18 inches tall and wide), forming a dense, compact mound with vibrant variegation

Minimal care required. Cut back dead foliage in late winter before new growth emerges. Divide every 4-5 years if desired.

Flowering

2-4 weeks

Inconspicuous brown or tan flower spikes appear among foliage in late spring (not ornamental)
