Seedling
2-3 weeksTiny seedlings with thread-like cotyledons emerge within 7-10 days. Delicate foliage is feathery and fine-textured.
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing once true leaves appear.
Vegetative Growth
3-4 weeksPlant develops bushy, mounding form with increasingly fine, thread-like foliage. Compact, low-growing habit becomes apparent.
Water moderately; let soil dry slightly between waterings. No fertilizer needed in fertile soil. Pinch back leggy growth to encourage bushiness.
Budding
2-3 weeksFlower buds form at stem tips. Fine thread-like foliage creates an airy, delicate appearance.
Continue moderate watering. Begin deadheading spent flowers if any bloom early. Avoid excess nitrogen.
Flowering
8-12 weeksAbundant daisy-like blooms with burgundy-red centers and distinctive golden-yellow laced edges appear. Plants are covered in color.
Deadhead spent flowers regularly to extend bloom period through fall. Water during dry spells but allow some drying between waterings.
Decline & Seed Production
4-6 weeksAs temperatures cool or plants naturally decline, some flowers are left to develop seeds for self-seeding next season.
Stop deadheading if you want self-seeding. Allow seeds to mature and dry on plants. Collect seed heads for storage or allow natural dispersal.
