Vegetative Growth
2-4 yearsPlant develops into a larger rosette, 2-3 feet in diameter, with increasingly dense foliage; no flowering yet
Minimal watering needed; only during extended drought. Remove any dead or damaged leaves. Maintain excellent drainage to prevent root rot.
Pre-Flowering
Several months before floweringMature rosette reaches 3-4 feet diameter; plant begins developing the flowering spike at center
Continue minimal watering. No fertilizer needed. Ensure adequate sunlight. Plant should not be stressed as this triggers flowering.
Flowering
3-4 monthsImpressive tall spike emerges from center, reaching 6-12 feet tall, covered with thousands of small cream to pale yellow flowers arranged in panicles
Provide full sun exposure for optimal flower development. No supplemental water needed unless experiencing extreme drought stress. The spike will persist for several months.
Seed Development & Maturation
4-6 monthsFlowers fade and develop small brown seed capsules along the spike; foliage continues to maintain rosette form
Allow spike to remain for visual interest or remove if desired. Seeds will mature over several months. Plant is fully hardy and requires no special care.
