Rhizome Dormancy/Early Growth
2-4 weeksRhizomes are planted and initial root development occurs underground with minimal above-ground growth.
Plant rhizomes in spring after frost danger passes. Ensure excellent drainage to prevent rot. Keep soil warm (65-70°F) and lightly moist. Mulch lightly.
Vegetative Growth
4-6 weeksLeafy stems emerge and elongate rapidly, developing lance-shaped foliage along tall, sturdy stems.
Provide consistent moisture and full sun. Support tall varieties with stakes if needed. Feed with balanced fertilizer every 2 weeks. Remove any diseased foliage.
Budding
2-3 weeksTerminal clusters of buds form at the top of stems, showing color development as buds swell.
Maintain consistent watering and increase phosphorus-rich fertilizer to promote flowering. Ensure adequate sunlight. Begin staking taller varieties if not done earlier.
Flowering
4-8 weeks per flush; repeats throughout seasonVibrant red and orange flowers with dark red stripes and yellow throats open sequentially along the inflorescence, creating a long display.
Remove spent flower clusters to encourage continued blooming. Maintain regular watering. Deadhead faded flowers to extend bloom season. Cut flowers in early morning for arrangements.
Post-Bloom/Dormancy Preparation
6-8 weeksAfter flowering ceases in late fall, foliage yellows and dies back as the plant enters dormancy for winter rest.
Reduce watering as foliage declines. Allow above-ground growth to die back completely. Do not cut prematurely. Mulch rhizomes in colder zones (8a-8b). Avoid disturbing rhizomes.
