Dormancy/Planting
Ongoing until spring growth beginsBare rhizomes with dried foliage; plant in fall (August-October) or early spring
Choose a location with excellent drainage. Position rhizomes with flat side down, crown slightly exposed. Firm soil around but not over the rhizome.
Spring Growth
4-6 weeksNew foliage emerges as narrow, sword-like leaves in a fan pattern
Water moderately as growth begins. Remove any dead foliage from previous season. Monitor for slugs and snails.
Budding & Flowering
2-3 weeks of bloom per seasonFlower buds form among the foliage; vibrant orange-red blooms with characteristic beard (fuzzy line on falls) emerge
Ensure adequate sunlight for color intensity. Stake if needed in windy locations. Deadhead spent flowers to maintain appearance. Avoid wetting foliage.
Post-Bloom & Ripening
4-6 weeksFlowers fade; seed pods may develop; foliage continues photosynthesis and energy storage
Remove seed pods to redirect energy to rhizome development unless you want to save seed. Reduce watering. Foliage continues to nourish the rhizome.
Summer Dormancy
6-8 weeksFoliage may yellow and die back naturally; rhizome rests underground
Minimal watering needed. Allow foliage to die back naturally. Cut back dead foliage in fall. This is a natural cycle; do not overwater or apply excessive fertilizer.

Harvest Tips
Not typically harvested. Enjoy blooms in place. If cutting flowers for arrangements, cut in early morning, remove lower foliage, and place in cool water immediately. Blooms last 1-2 weeks indoors. For seed collection, allow pods to dry on plant until brown, then harvest and dry seeds further before storage.
