Dormancy/Establishment
Autumn through early spring (4-6 months)Freshly planted rhizomes are dormant; minimal visible growth above ground
Plant in fall (September-October) or early spring. Ensure excellent drainage. Water moderately to establish. Keep foliage dry.
Spring Growth
March-April (4-6 weeks)Sword-like green leaves emerge and elongate; plant develops new fans of foliage
Monitor for rhizome rot in wet conditions. Remove any dead foliage. Increase watering as growth accelerates.
Flowering
Late April-May (2-3 weeks)Tall flower stems emerge with 2-3 blooms per stem; white petals with blue-purple plicata markings open fully
Stake taller stems in windy areas. Remove spent flowers daily for extended bloom. Do not deadhead the stem until all buds are spent.
Post-Bloom/Summer
June-August (3 months)Flowers fade; foliage continues to mature and photosynthesize; rhizome energy is redirected to growth and next year's bloom
Reduce watering gradually. Allow foliage to remain until it dies back naturally. Avoid fertilizing after bloom.
Dormancy
September-February (5-6 months)Foliage yellows and dies back; rhizomes enter dormancy for winter rest
Cut back dead foliage in fall. Minimal watering. Protect in very cold zones with light mulch if needed.

Harvest Tips
Cut flowers in early morning when buds are just opening for longest vase life (5-7 days). Cut stems at an angle and strip lower foliage. Recut stems every 2-3 days.
