Seedling
2-4 weeksTiny feathery foliage emerges; plants are very delicate and prone to damping off
Keep soil moist but not waterlogged; ensure good air circulation; thin seedlings to proper spacing early
Vegetative
4-8 weeksFinely divided, fern-like foliage develops into dense mounds; plant grows steadily without flowering
Water moderately during establishment; pinch back in early season to encourage bushiness; deadhead any early flowers to promote branching
Flowering
8-12 weeks (early summer to fall)Dense, flat-topped flower clusters (corymbs) in deep burgundy-red appear at branch tips; flowers are tiny but numerous
Deadhead spent flowers regularly to extend bloom time; provide stake support only if needed in windy locations; reduce watering once flowering begins
Seed Development
4-6 weeksFlower clusters dry and brown on the plant; seeds mature within the dried flower heads
Allow some flowers to dry on plant for seed collection or ornamental interest; cut back in late fall or early spring
Dormancy
3-4 months (winter)Plant dies back completely in late fall/winter; underground root system survives cold
Cut stems to 2-3 inches above ground in late fall; no watering needed; mulch lightly in colder zones for extra protection

Harvest Tips
Cut flowers for arrangements when the flat flower clusters are fully open but still vibrant in color; pick in early morning for longest vase life (7-10 days). For dried flowers, harvest just after peak bloom and hang upside down in a warm, airy location for 2-3 weeks. Deadhead regularly during the season to encourage continuous blooming and prevent self-seeding.
