Vegetative Growth
3-4 weeksPlant develops 4-8 true leaves and begins branching. Foliage is soft, lance-shaped, and light green.
Transplant to larger pots once true leaves appear. Maintain consistent moisture. Begin hardening off seedlings 1-2 weeks before planting outdoors.
Bud Formation
2-3 weeksDense flower buds form at stem tips, beginning as compact green clusters that lengthen slightly.
Provide full sun exposure. Ensure adequate spacing for air circulation. Water consistently. Fertilize biweekly with balanced to slightly high-phosphorus formula.
Flowering
8-12 weeks (or until frost)Dramatic velvety flower plumes emerge in deep red with silvery-white frosted tips, resembling flames. Multiple blooms develop along stems.
Deadhead spent flowers to encourage continuous blooming. Water at soil level. Apply balanced liquid fertilizer every 2 weeks. Monitor for pests. Enjoy for cutting.
Seed Setting & Decline
VariesIf flowers are not deadheaded, seed heads develop. Plant may slow flowering as energy shifts to seed production. Dies with hard frost.
Allow some flowers to mature for seeds if desired. Cut dried plumes for floral arrangements. Plants may continue producing until first hard frost.
