Germination & Seedling
2-3 weeksTiny seedlings with fine, thread-like cotyledons emerge in 7-10 days. Plants develop delicate, feathery foliage from the start.
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing once they have first true leaves. Do not fertilize heavily.
Vegetative Growth
3-4 weeksPlant develops bushy mounding form with increasingly feathery foliage. Stems become more sturdy and branching increases.
Allow soil to dry between waterings. Do not overwater or overfertilize, as this encourages leaf growth at expense of flowers. Pinch tips if bushier growth is desired.
Bud Formation
1-2 weeksDistinctive spherical flower buds begin forming at stem tips. Plant becomes noticeably denser with visible bud clusters.
Maintain moderate watering. Apply light, low-nitrogen fertilizer if desired, or rely on native soil fertility. Ensure full sun exposure for best bud development.
Flowering
4-8 weeks (or longer with deadheading)Spherical clusters of tiny lavender-blue, sometimes white or pink flowers open progressively. Each flower head resembles a delicate pompom.
Deadhead spent flower heads to encourage continuous blooming. Water moderately; reduce watering if plant shows signs of stress. Provide support stakes if plants become leggy in shade.
Seed Production & Decline
2-3 weeksIf flowers are left on plant, small seed capsules develop. Plant gradually declines as annual cycle completes.
Allow some flowers to remain if you want seed collection for next year. Collect ripe seed pods before shattering. Remove spent plants at season's end.
