Growth Stages

1

Establishment

3-4 months

Young plant develops initial root system and basal foliage. Leaves are lobed and deeply cut.

Water regularly to establish. Apply 2-3 inches of mulch. Avoid transplanting stress; allow first year to settle.

2

Vegetative Growth

Spring through mid-summer

Plant builds multiple stems and fuller foliage clumps. Stems grow tall and woody.

Provide support stakes or grow-through cages as stems elongate. Water consistently. Fertilize lightly monthly.

3

Bud Formation

4-6 weeks

Flowering stems develop flower buds at branch tips, typically appearing in late summer.

Continue watering and staking. Avoid nitrogen-heavy fertilizers to promote blooms over foliage.

4

Flowering

6-8 weeks (August-October)

Deep violet-purple single flowers with golden-yellow centers open progressively along stems. Blooms are 2-3 inches wide.

Deadhead spent blooms to encourage continued flowering. Stake taller stems if needed. Enjoy cut flowers.

5

Dormancy

November-March

Foliage dies back after frost. Underground rhizomes remain dormant underground.

Cut back dead stems to 2-3 inches. Apply light mulch for winter protection. No watering needed.
