Seed/Germination
2-3 weeksTiny seeds germinate on cool, moist soil surface. Seedlings develop cotyledons and first true leaves.

Seedling & Juvenile
4-8 weeksYoung plants develop finely divided, pinnate foliage in a low rosette. Growth is slow initially.
Provide excellent drainage to prevent damping off. Grow in cool conditions. Reduce watering frequency as plants mature.
Vegetative/Rosette
6-10 weeksPlant forms a dense basal rosette of attractive, finely textured foliage. Compact mounding habit develops.
Allow adequate air circulation. Remove any diseased or dead leaves. No fertilizer needed; low fertility is preferred.
Flowering
6-10 weeksSlender stems emerge from rosette, each bearing bright orange-red semi-double or double flowers. Peak bloom occurs in late spring and early summer.
Deadhead spent flowers to encourage continued blooming. Water at soil level to keep foliage dry. Support tall stems if needed.
Seed Production/Maturity
4-8 weeks post-floweringAfter flowering, plants produce ornamental seed heads if flowers are left to mature. Foliage remains attractive throughout growing season.
Allow some flowers to remain for seed production or ornamental interest. Cut back old growth in autumn or early spring.
