Growth Stages

Establishment

4-8 weeks

Young plant developing root system and branching structure

Water regularly to keep soil moist. Stake if needed in windy locations. Avoid fertilizing for first 4-6 weeks.

Vegetative Growth

Spring through early summer

Compact branching develops; foliage becomes distinctly purple-tinted; new growth appears

Light pruning to shape and encourage bushier form. Deadhead spent flowers to promote branching. Minimal fertilizer application.

Flowering

Late spring through fall (extended in mild climates)

Delicate lavender-blue flower spikes emerge along branch tips; foliage remains vibrant purple

Deadhead regularly to encourage continuous blooming. Maintain consistent moisture. Light feeding with balanced fertilizer acceptable.

Dormancy/Winter Rest

November through February

Growth slows; purple foliage deepens; flowering diminishes or stops in colder zones

Reduce watering significantly. Protect from hard freezes with mulch or frost cloth in zone 8b. Prune dead or frost-damaged wood in spring.
