Spring Emergence
4-6 weeksShoots emerge from dormant rhizomes; foliage begins unfurling with deeply lobed, dark green leaves
Remove winter mulch as soil warms. Apply balanced fertilizer. Ensure consistent moisture as growth accelerates.
Vegetative Growth
6-8 weeksPlant develops mounding habit with increasingly dense foliage; leaves reach full size (3-4 inches long)
Deadhead any early flowers to encourage bushy growth. Water regularly. Stake if needed for taller stems. Apply balanced fertilizer mid-season.
Bud Formation
3-4 weeksFlowering stems elongate; tight buds form at branch tips, gradually enlarging and pinkening
Maintain consistent moisture; drought stress reduces flower production. Stop fertilizing to avoid excessive vegetative growth. Stake taller stems if needed.
Flowering
8-12 weeks (late August through October)Semi-double, soft pink flowers with darker pink centers open successively along stems; blooms 2-2.5 inches wide
Deadhead spent flowers to extend bloom season. Cut flowers for arrangements when buds just open. Continue watering during bloom.
Senescence
4-8 weeksBlooms fade; seed heads develop; foliage gradually yellows and dies back with first frost
Allow some flowers to go to seed for self-seeding; cut back dead foliage to ground in late fall. Apply 2-3 inches of mulch for winter protection in zones 4-5.
