Seedling
2-3 weeksTiny seedlings emerge with cotyledons and fine, thread-like true leaves beginning to show the characteristic feathery foliage pattern.
Keep soil moist but not wet; provide bright light. Thin seedlings to proper spacing once they have 2-3 true leaves. No bottom heat required.
Vegetative Growth
4-8 weeksPlant develops a mounding habit with increasingly dense, finely-dissected foliage. Stems thicken and the plant becomes bushier.
Water moderately during establishment. Pinch back once or twice in early summer to promote a fuller shape and more flower clusters. Ensure good air circulation.
Budding & Early Flowering
3-4 weeksFlower buds form at stem tips, gradually opening into dense, flat-topped flower clusters (umbels) with vibrant red-burgundy florets and yellow centers.

Peak Flowering
6-10 weeks (June-August typically)Plant is covered with multiple clusters of brilliant red-burgundy flowers with contrasting yellow centers, creating a showy display.
Continue deadheading for prolonged bloom. Water during dry spells. Watch for powdery mildew in humid conditions; improve air circulation. Attract pollinators.
Seed Maturation & Dormancy
4-6 weeks through fallFlowers fade and dry to tan-brown seed heads; foliage may decline in late summer. Plant enters semi-dormancy.
Allow some flowers to dry on the plant for seed dispersal and winter interest. In fall, cut back old growth to 2-3 inches above ground after frost. Divide congested plants every 3-4 years in spring or fall.
