Growth Stages

1

Establishment

First year

Young plant with compact growth habit; foliage begins showing variegation; minimal flowering

Water regularly to keep soil moist; mulch around base with 2-3 inches of pine needles or peat moss; shelter from harsh winds

2

Vegetative Growth

Year 2-3

Plant develops fuller branching structure; distinctive silver-white variegated foliage becomes more pronounced; foliage may develop pink or red hues in cool temperatures

Light pruning after flowering to maintain shape; ensure consistent moisture; avoid overhead watering to prevent fungal issues

3

Flowering

August-October

Delicate, wiry flower spikes emerge from branch tips in late summer through fall; flowers range from pale pink to white with darker centers

Deadheading extends blooming; avoid pruning before flowers form; reduce nitrogen fertilizer to encourage blooming

4

Winter Dormancy

November-March

Foliage color intensifies with reddish or bronze tones; flowers fade and dry on stems; growth slows significantly

Reduce watering but don't allow soil to completely dry; mulch heavily in colder zones; leave seed heads for winter interest

5

Mature Plant

Year 4 onwards

Fully developed mounding shrub with dense foliage; reliable annual flowering; strong ornamental value year-round

Prune lightly after flowering to maintain compact form; top-dress with compost annually; monitor for spider mites in hot, dry conditions
