Seedling
2-3 weeksTiny seedlings with 2-4 true leaves; very delicate and small. Foliage is narrow and light green.
Keep soil consistently moist but not waterlogged. Provide bright light (grow lights if indoors). Thin seedlings if crowded to prevent damping off.
Establishment
3-4 weeksYoung plants develop more foliage and a stronger root system. Plant reaches 6-12 inches tall with increasing stem branching.
Gradually acclimate to outdoor conditions if started indoors. Water regularly but allow soil to dry slightly. Pinch back growing tips to encourage bushier growth.
Vegetative Growth
4-6 weeksRapid stem and leaf development. Plant develops its characteristic tall, airy structure with thin stems and narrow, linear leaves. Height increases from 12 inches to 24-36 inches.
Support tall stems with stakes if needed in windy locations. Reduce fertilizing—too much nitrogen promotes excessive foliage at expense of flowers. Water during dry spells.
Flowering
8-12+ weeks (June/July through first frost)Abundant clusters of tiny purple-violet flowers appear at stem tips. Flowers arranged in rounded panicles. Blooming is continuous and prolific from midsummer onward.
Deadhead spent flower clusters to encourage continued blooming. Water moderately; drought stress can actually intensify flower color. No fertilizing needed.
Senescence/Dormancy
October onward depending on zoneWith first hard freeze, foliage blackens and plant dies back (or becomes evergreen in zones 9-10). Seed heads may remain on dried stems.
In zones 6-8, cut back to base in late fall or early spring. Leave for wildlife habitat if desired. In mild zones, may persist and regrow from base. Collect seeds before heavy frost for next season.
