Planting & Dormancy
September-FebruaryRhizomes are planted in fall (September-November); foliage remains relatively dormant through winter with minimal visible growth
Plant in well-prepared beds with excellent drainage. Water after planting. Ensure soil drains well to prevent rot.
Early Growth
February-MarchFine, grass-like reticulated foliage emerges in late winter to early spring; root systems develop and new shoots push upward
Monitor for excessive moisture. Remove any debris. Begin light fertilization as growth accelerates.
Bud Formation & Flowering
March-AprilCompact flower stems emerge with tight buds, opening into fragrant, purple-blue blooms with distinctive bearded falls and standards
Protect from heavy rain and wind if possible. Deadhead spent flowers to maintain appearance. Enjoy the fragrance.
Post-Bloom & Foliage
April-JuneFlowers fade; fine green foliage remains ornamental throughout spring and early summer before natural senescence
Allow foliage to persist and photosynthesize to strengthen rhizomes. Reduce watering as growth slows.
Summer Dormancy
June-SeptemberFoliage yellows and dies back completely; plant enters dormancy as soil warms and moisture decreases naturally
Minimize water; allow natural dry-down. Do not disturb rhizomes. Dormancy strengthens next year's blooms.
