Seedling
2-4 weeksTiny cotyledons emerge; first true leaves are pinnately divided and hairy. Plant develops a small rosette of finely textured foliage.
Keep soil lightly moist but not wet. Ensure good air circulation to prevent damping off. Thin seedlings to proper spacing once 2-3 true leaves appear.
Vegetative Growth
4-8 weeksCompact mound forms with increasingly dense, gray-green, pinnate foliage. Plant builds root system and establishes framework for flowering.
Water sparingly; allow soil to dry between waterings. Do not fertilize heavily as this encourages foliage at expense of flowers. Thin weak growth if overcrowded.
Budding & Flowering
8-12 weeksDense, rounded flower heads (pompom-like inflorescences) appear at stem tips in vivid scarlet-red or orange-red. Flowers open progressively from bottom to top of each head.
Deadhead spent flower heads to encourage continued blooming and prevent excessive self-seeding. Water only during extended dry spells. No fertilizer needed.
Seed Production & Maturation
4-6 weeksIf allowed, flowers fade and develop into small, hard seed pods within the dried flower head structure. Foliage may become less vibrant as plant's energy shifts to seed production.
Leave some flower heads for seed collection or natural drop. Cut back overgrown stems in late summer if desired. Reduce water input; plant prepares for dormancy.
Winter Dormancy
3-4 monthsPlant enters dormancy, foliage turns bronze or gray, and growth ceases. In milder zones, plant may retain some foliage.
No watering needed in winter. Ensure excellent drainage to prevent rot during wet months. Avoid mulch over crown; use gravel instead. Remove any dead foliage in early spring.
