Growth Stages

1

Dormancy/Emergence

2-4 weeks

Plant emerges in early spring with delicate, fern-like foliage breaking through soil

Ensure soil is moist; apply mulch to retain moisture and moderate soil temperature; be patient as growth is gradual

2

Vegetative Growth

3-4 weeks

Fine, feathery foliage expands into mounding clumps; stems elongate to support flowering

Keep soil consistently moist; provide dappled shade; avoid full sun exposure which can scorch leaves; monitor for slugs

3

Flowering

4-6 weeks (spring through early summer)

Heart-shaped flowers in shades of pink, rose, or white appear on arching stems above foliage

Deadhead spent flowers to encourage continued blooming; provide afternoon shade; maintain soil moisture; fertilize lightly with balanced fertilizer

4

Post-Bloom/Summer Dormancy

4-6 weeks

Foliage yellows and dies back by mid-to-late summer, particularly in warmer zones; plant goes dormant

Reduce watering; allow foliage to naturally decline; do not remove dead foliage until completely dry; dormancy is natural and healthy

5

Dormancy Period

Several months (late summer through winter)

Plant appears absent from garden; rhizomes rest underground awaiting spring emergence

Mark planting location to avoid disturbing; maintain consistent soil moisture but do not overwater; apply winter mulch in colder zones
