Seedling
2-3 weeksTiny seedlings emerge with delicate, fine-textured leaves. Plants are fragile and need consistent moisture without waterlogging.
Keep soil moist but not wet. Provide bright light. Thin seedlings to proper spacing once they have 2-3 true leaves. Avoid damping off by ensuring good air circulation.
Vegetative Growth
4-8 weeksYoung plants develop their characteristic feathery, fern-like foliage in mounding clumps. Foliage is soft and grows outward.
Water regularly to establish deep root systems. Pinch back growing tips in early season to encourage bushier, fuller plants. Reduce watering as plant matures. Remove weeds as needed.
Budding & Early Flowering
2-3 weeksStems elongate and flat-topped flower clusters (umbels) form at branch tips. Florets begin to open, initially showing softer pastel tones.
Deadhead spent blooms regularly to encourage continuous flowering. Ensure adequate water during flowering. Stake taller stems if needed in windy locations. Colors intensify as flowers age.
Peak Flowering
4-8 weeksFully open flower clusters display full range of pastel colors. Plant is at its most ornamental and attractive to pollinators.
Continue deadheading to promote more flowers. Cut stems for bouquets or drying. Maintain consistent watering. Monitor for pests and diseases. Colors may shift slightly as flowers age.
Decline & Seed Set
4-6 weeksIf not deadheaded, flowers fade and seed heads form. Foliage may begin to yellow toward late summer in hot climates.
Leave some flowers for drying or seed heads for birds if desired. Cut back in fall after frost or in early spring before new growth. Divide crowded plants every 3-4 years.
