Rhizome Establishment
2-4 weeksNewly planted rhizome develops roots and shoots emerge from the top of the rhizome
Plant in fall or early spring. Keep soil moderately moist but not waterlogged. Ensure excellent drainage to prevent rhizome rot.
Vegetative Growth
3-4 monthsFan-like foliage develops with long, sword-shaped blue-green leaves reaching 12-18 inches tall
Monitor for leaf spot diseases in humid conditions. Avoid overhead watering. Remove dead or diseased foliage. Apply balanced fertilizer in spring.
Budding & Pre-Bloom
3-4 weeksTall flower stems emerge with multiple buds forming along the stem, each bud encased in papery spathes
Provide consistent moisture as buds develop. Stake tall varieties if in windy locations. Apply low-nitrogen fertilizer to support blooming.
Flowering
2-3 weeksLarge ruffled blooms open sequentially, displaying golden-yellow standards and mahogany-red falls with golden beards
Remove spent flowers daily to encourage more blooms to open. Enjoy fragrance. Stake stems if they bend under bloom weight. Do not overwater.
Post-Bloom & Dormancy
4-6 monthsFlowers fade and drop; foliage remains green but growth slows. Rhizome enters period of rest in late summer/early fall
Cut flower stems at base after blooming. Trim brown leaf tips. Reduce watering in late summer. Do not fertilize after July. Divide overcrowded clumps every 3-4 years in late summer.
