Growth Stages

Seedling

2-3 weeks

Tiny seedlings with fine, delicate foliage emerge from the soil

Keep soil lightly moist but not wet; provide bright light; thin seedlings to proper spacing once established

Vegetative

6-8 weeks

Plant develops bushy growth with fine, feathery foliage; no flowers yet

Water during dry periods to encourage root establishment; pinching back shoots encourages branching for fuller plants

Budding & Flowering

8-12 weeks

Delicate blue-purple flower buds form in misty clusters at branch tips; flowers begin opening

Reduce watering as plant is now drought-tolerant; deadheading extends bloom period but is optional

Peak Bloom

8-10 weeks (late summer through fall)

Plant is covered in airy clusters of small blue-purple flowers, creating a hazy, misty appearance

Minimal maintenance; butterflies and pollinators actively visit; allow some flowers to remain for seed production

Seed Production & Dormancy

Throughout winter

Flowers fade; small seeds develop in dried flower clusters; foliage dies back with first frost

Allow seeds to drop for self-seeding next year; cut back dead growth in late fall or early spring
