Growth Stages

1

Seedling/Transplant

2-4 weeks

Small plants with emerging silvery-gray foliage, 2-4 inches tall

Water sparingly; ensure excellent drainage. Provide bright light indoors or dappled light outdoors. Harden off transplants gradually.

2

Vegetative Growth

4-8 weeks

Rapid foliage development with increasingly silvery, finely cut leaves forming a mounded shape

Water moderately during dry spells. No fertilizer needed; excess nitrogen reduces silver coloration. Pinch tips in early season to encourage bushiness.

3

Mature Foliage

Extends through growing season

Full-sized plant with dense, silvery-white foliage creating a striking ornamental appearance, 18-24 inches tall and wide

Maintain as primarily foliage plant. Deadhead flower buds if preferred for aesthetic reasons. Reduce watering in summer if rain is adequate.

4

Flowering

4-6 weeks

Inconspicuous tiny yellow flowers on slender spikes above the foliage, late summer

Flowering is secondary to foliage appeal. Deadhead to redirect energy back to leaf production and maintain compact shape.

5

Dormancy/Decline

3-4 months (winter)

Foliage may fade or become bronze-tinged in fall and winter; plant dies back or persists as evergreen semi-woody base depending on climate

Stop watering in winter; plant is dormant. Cut back dead growth in early spring before new growth emerges. In cold zones, mulch lightly.

Harvest Tips

This is a foliage plant, not typically harvested for food. For floral arrangements and crafts, cut sprigs of silvery foliage anytime during the growing season. Foliage is most vibrant and silvery in mid-summer. Stems can be cut for dried flower arrangements; hang-dry in a warm, dry location for 2-3 weeks. Rejuvenation pruning in early spring removes old woody growth and promotes fresh, colorful foliage.
