Growth Stages

1

Establishment

4-8 weeks

Young transplant with small rosette of purple foliage, still developing root system

Water regularly to keep soil moist without waterlogging. Shelter from strong wind. Apply light mulch around (not touching) crown

2

Vegetative Growth

Spring through summer, 4-6 months

Plant expands with increasing number of deeply colored purple leaves forming a dense mound

Water consistently, maintain mulch layer, fertilize lightly in spring with balanced fertilizer. Remove any dead or damaged leaves

3

Flowering

Late spring to mid-summer, 6-8 weeks

Tall, delicate flower spikes (12-18 inches) emerge above foliage, bearing small pink, white, or red-tinged flowers

Spikes may benefit from staking in windy locations. Deadhead spent flowers to encourage continued blooming and neaten appearance

4

Summer Rest

Mid-summer, 4-8 weeks

Plant growth slows in hot summer months; foliage color may become less vibrant in extreme heat

Increase watering in hot weather, provide afternoon shade in zones 8-9, avoid high-nitrogen fertilizers that may reduce cold hardiness

5

Fall & Winter Dormancy

Fall through winter, 4-6 months

Foliage may develop reddish or bronze tones as temperatures cool. Plant enters semi-dormancy, leaves persist but growth stops

Reduce watering, avoid fertilizing, do not cut back foliage in fall (provides insulation). Clean up dead leaves in early spring only
