Growth Stages

1

Seedling

2-3 weeks

Tiny, narrow-leaved seedlings with cotyledons emerge within 7-10 days. Foliage is fine and delicate.

Keep soil moist but well-draining. Provide bright light and cool temperatures (60-65°F). Thin seedlings to prevent damping-off.

2

Vegetative Growth

3-4 weeks

Compact mound of narrow, blue-green foliage develops. Plant reaches full width and height without blooms.

Fertilize monthly with balanced fertilizer. Remove any yellowed foliage. Harden off before transplanting outdoors.

3

Budding

1-2 weeks

Flower buds form at stem tips. Buds are small, rounded, and deep red.

Avoid overwatering during this stage. Maintain consistent watering without waterlogging. Do not disturb plants.

4

Flowering

8-12 weeks (continuous with deadheading)

Full double flowers bloom in rich crimson-red. Petals are ruffled with a carnation-like appearance. Multiple flowers open simultaneously.

Deadhead spent flowers to encourage continuous blooming. Water at base only. Avoid wetting flowers to prevent fungal disease.

5

Extended Bloom & Senescence

Variable; can bloom into fall

Plant may slow blooming in peak heat (above 85°F) or late season. Foliage remains ornamental even if flowers diminish.

Provide afternoon shade in hot climates. Cut back lightly if plants become leggy. Deadhead regularly to extend season.
