Dormancy
2-4 monthsRhizome lies dormant underground with minimal visible growth, typically during winter or summer depending on variety.
Protect from extreme cold with mulch in zones 3-4. Allow soil to dry out; avoid waterlogging.
Spring Growth
4-6 weeksFoliage emerges as upright, sword-like green leaves. Growth accelerates as temperatures warm.
Reduce mulch as growth begins. Remove any dead foliage from previous year. Begin fertilizing with iris-specific or balanced fertilizer.
Flowering
2-3 weeksTall flower stalks develop bearing 2-3 blooms per stem. Flowers display deep sapphire-blue standards with golden-yellow beards on falls.
Stake if needed in windy locations. Deadhead spent flowers to encourage multiple blooms on same spike. Do not remove foliage.
Post-Bloom
4-6 weeksFlowers fade and seed pods develop. Foliage continues to photosynthesize, storing energy in rhizomes.
Remove seed pods unless saving seed. Continue moderate watering. Let foliage remain until it naturally yellows (do not remove until brown).
Summer Rest
2-3 monthsFoliage gradually yellows and dies back. Rhizome enters dormancy period.
Reduce watering significantly. Remove dead foliage once fully brown. Withhold fertilizer. This is ideal time for division if needed.
