Seed and Germination
10-14 daysSeeds are tiny and require light exposure to germinate. Seedlings are delicate with cotyledons and first true leaves.
Do not bury seeds. Keep soil lightly moist until germination (10-14 days). Start indoors in late winter for spring transplant, or direct sow after last frost.
Seedling to Transplant
4-6 weeksDevelops true leaves and establishes a taproot system. Plants remain low and compact.
Provide bright light to prevent leggy growth. Allow soil to dry between waterings. Transplant outdoors after all frost danger passes.
Vegetative Growth
4-8 weeksPlant develops basal rosettes of silvery-green, finely divided foliage. Growth is spreading and mounding.
Water moderately during establishment (first 4-6 weeks after transplanting). Once established, reduce watering significantly. No fertilizer needed.
Flowering
2-3 months (June-August, or longer in warm climates)Produces dense clusters of small, bright orange-red to coral flowers on short stems above the foliage. Continuous blooming occurs.
Deadhead spent flowers to encourage more blooms, though not essential. The plant self-seeds readily if flowers are allowed to mature. Minimal maintenance required.
Seed Maturation and Winter Dormancy
2-3 monthsFlowers develop into round seed capsules. Foliage may decline in very hot conditions or enter dormancy in fall/winter.
Allow seed pods to mature if self-seeding is desired. Cut back dead foliage in early spring. Provide no supplemental water during dormancy.
