Growth Stages

1

Seed/Germination

2-3 weeks

Tiny seedlings emerge 10-14 days after sowing. Seeds require light to germinate.

Do not cover seeds. Keep soil moist but not waterlogged. Provide bright light. Thin seedlings to appropriate spacing once true leaves develop.

2

Vegetative/Establishment

4-6 weeks

Plant develops feathery, finely divided foliage. Grows herbaceous stems 12-24 inches tall.

Water regularly to establish deep roots. Apply light mulch. Fertilize monthly with balanced fertilizer. Deadhead spent flowers to encourage branching.

3

Budding

2-3 weeks

Flower buds form at stem tips, clustering into flat-topped inflorescences.

Reduce nitrogen fertilizer to encourage flowering over foliage. Maintain consistent moisture. Stake tall varieties if needed.

4

Flowering

8-12 weeks (June-September, depending on zone)

Brilliant red to orange-red flat-topped flower clusters (corymbs) bloom profusely. Flowers attract butterflies and other pollinators.

Deadhead spent flowers to extend blooming season into fall. Water during dry spells. Monitor for powdery mildew in humid conditions.

5

Dormancy/Overwintering

November-March (varies by zone)

Foliage dies back after first hard frost. Plant enters dormancy underground.

Cut back dead stems in late fall or early spring. Leave some stems standing for winter interest and wildlife shelter. No water needed. Mulch lightly in zones 3-4 if exposed.
