Growth Stages

1

Establishment

6-8 weeks

Newly planted divisions or transplants develop roots and initial foliage. Leaves emerge from soil as rhizomes establish.

Keep soil consistently moist during first season. Mulch around base. Don't expect full flowering in year one.

2

Vegetative Growth

6-10 weeks

Plant produces bushy mounded foliage with lobed leaves. Stems elongate throughout summer; no flower buds visible yet.

Remove any early flower buds in first year to encourage root establishment. Water regularly. Stake if in windy location.

3

Bud Formation

3-4 weeks

In late summer (July-August), flower buds form at stem tips. Buds appear as small nodules that gradually enlarge.

Ensure adequate moisture and phosphorus. Don't cut back plants. Support tall stems with stakes or cages if needed.

4

Flowering

6-8 weeks (August-October)

Semi-double pink flowers with 8-12 petals bloom prolifically. Flowers reach 1.5-2 inches across on tall branching stems. Blooms progress from top to bottom.

Deadhead spent flowers to encourage continued blooming. Water during dry spells. Support mature plants with stakes. Watch for root diseases in overly wet conditions.

5

Senescence

4-6 weeks

Flowers fade and seed heads form. Foliage begins to yellow and die back as temperatures drop. Plant enters dormancy.

Cut back dead foliage in late fall or early spring. Apply winter mulch in colder zones (4-5). Leave standing through winter for visual interest if desired.
