Growth Stages

1

Establishment

6-8 weeks

Young transplant develops root system and grows leafy stems

Keep soil consistently moist. Provide afternoon shade in hot climates. Mulch around base to retain moisture.

2

Vegetative Growth

8-12 weeks

Plant develops full bushy form with deep green lance-shaped leaves along sturdy upright stems

Pinch back stem tips in early summer (before June 15 in northern zones) to encourage bushier, more compact growth and more flower clusters. Apply balanced fertilizer monthly.

3

Budding & Flowering

8-12 weeks (mid-summer through fall)

Dense panicles of pale pink flowers with deep red/purple eyes form at stem tips; blooms are fragrant and highly visible

Deadhead spent flower clusters to encourage continued blooming. Ensure adequate water during bloom. Support tall stems with stakes if needed in windy locations.

4

Late Bloom & Senescence

4-6 weeks before frost

Flower production slows as temperatures cool; foliage may show some powdery mildew or yellowing

Continue deadheading to extend bloom. Remove any diseased leaves. Reduce watering slightly as growth slows.

5

Dormancy

Winter months

Plant dies back to ground after frost; perennial root system persists underground

Cut back dead foliage to 2-3 inches in late fall or early spring. Apply 2-3 inches of mulch for winter protection in cold zones. Clean up debris to reduce pest/disease overwintering.
