Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with 2-4 true leaves emerge; plants are delicate and require humid conditions

Maintain consistent moisture without waterlogging. Provide bright, indirect light. Avoid damping off by ensuring good air circulation.

2

Vegetative Growth

4-8 weeks

Plant develops silvery-green fuzzy foliage and a bushy form; no flowers yet; stems strengthen and branch

Pinch back growing tips to encourage bushiness. Maintain even moisture and warm temperatures (65-75°F). Feed with balanced fertilizer every 2-3 weeks.

3

Flower Bud Formation

2-3 weeks

Terminal flower buds form at stem tips; plants appear fuller and more robust with dense foliage

Shift to lower nitrogen, higher phosphorus fertilizer to promote blooming. Ensure adequate light. Maintain warm conditions.

4

Flowering

8-12 weeks or longer

Dense spikes of tubular orange-red flowers appear; blooms attract hummingbirds and butterflies; flowers open progressively along spike

Deadhead spent flowers to encourage continuous blooming. Water consistently but avoid wetting flowers. Support tall stems if needed.

5

Dormancy/Overwintering

2-4 months

In cooler climates, plants slow growth; foliage may decline. In warm zones, flowering may continue with reduced vigor

Reduce watering significantly. Move containers indoors in zones 3-9. Cut back leggy stems. Provide cooler temperatures (50-60°F) if possible.
