Growth Stages

1

Seedling

3-4 weeks

Small plants with fine, feathery foliage emerging; very delicate appearance

Keep soil lightly moist but not waterlogged; provide bright light; thin seedlings to proper spacing

2

Vegetative Growth

4-6 weeks

Dense mounding habit developing with airy, thread-like foliage; plant reaches 12-15 inches tall

Reduce watering frequency; allow soil to dry between waterings; light fertilizing optional but not necessary

3

Flowering

12-16 weeks (June-October)

Abundant, delicate pale yellow daisy-like flowers appear on wiry stems; blooms cover much of the foliage

Deadhead spent flowers to encourage continuous blooming; water sparingly; stake only in windy locations

4

Seed Development

3-4 weeks

Flowers fade and small seed heads develop; foliage may yellow slightly

Allow some flowers to remain if self-seeding is desired; otherwise deadhead for neatness and continued blooming

5

Dormancy

3-4 months (November-March)

In cold climates, foliage dies back completely; in warm zones, foliage persists but growth slows

Cut back dead foliage to ground level in late fall or early spring; no watering needed; light mulch optional in zone 3-4
