Dormancy/Establishment
Fall through late winterRhizomes are planted in fall with minimal visible growth above ground
Plant in autumn (September-October) in cold climates. Ensure excellent drainage. Mulch lightly after first hard freeze. Water moderately during establishment.
Spring Growth
March-April (northern regions)Foliage emerges as green, sword-like leaves in early spring; plant appears compact and bushy
Remove winter mulch in early spring as growth begins. Feed with balanced or low-nitrogen iris fertilizer. Keep soil consistently moist but not waterlogged.
Budding & Flowering
April-MayFlower buds form on short stems; distinctive deep purple-red flowers with ruffled falls and beards appear
Do not allow soil to dry completely during this critical stage. Stake if needed in windy locations (rarely necessary due to short height). Deadhead spent flowers to maintain appearance.
Post-Bloom/Foliage
May-JuneAfter flowering, plant continues producing green foliage; seed pods may develop if flowers weren't deadheaded
Reduce watering gradually. Remove seed pods if present to direct energy to rhizome. Continue light feeding if soil is poor. Allow foliage to remain until it naturally yellows.
Summer Dormancy/Decline
July-AugustFoliage yellows and dies back; plant enters dormancy period with minimal visible activity
Dramatically reduce watering; allow soil to dry out. Do not fertilize. Remove dead foliage as it browns. This dormancy period is critical for next year's bloom.
