Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with delicate feathery leaves emerge within 7-14 days. Plants develop their characteristic fine, thread-like foliage.

Keep soil lightly moist until true leaves appear. Provide bright light to prevent legginess. Thin seedlings to 2-3 inches apart.

2

Vegetative

4-6 weeks from transplant

Bushy mounds of silvery-green feathery foliage develop, 12-18 inches tall. Foliage is aromatic and soft to touch.

Water moderately during dry spells. Pinch back young plants in early spring to promote bushier growth. Reduce watering as temperatures cool.

3

Budding & Early Flowering

2-3 weeks

Flower buds appear at stem tips, clustered in tight umbrella-like formations (corymbs). Early flowers show golden-yellow color.

Ensure full sun exposure for peak color. Deadhead spent flowers to encourage continuous blooming. Water at soil level to keep foliage dry.

4

Peak Flowering

4-6 weeks or longer with deadheading

Full, dense clusters of golden-yellow flowers mature, gradually shifting to cream and peachy-orange tones as they age, creating multi-hued displays.

Deadhead regularly to extend bloom season into fall. Reduce water frequency. Monitor for powdery mildew in humid conditions.

5

Seed Maturation & Winter Rest

6-8 weeks into dormancy

Flowers fade to tan, flower heads dry and persist ornamentally. Foliage begins to deteriorate in cold climates.

Allow some spent flowers to remain for wildlife and winter interest, or cut back to 4-6 inches above ground in late fall. Do not cut back in mild winter zones until spring growth begins.
