Growth Stages

1

Seedling

4-6 weeks

Tiny rosettes with 2-4 small leaves emerge from seed

Keep soil lightly moist. Provide bright, indirect light. Maintain cooler conditions (50-60°F) for germination.

2

Vegetative Rosette Development

8-12 weeks

Compact evergreen rosettes expand gradually with multiple leaves arranged in neat circular patterns

Water moderately but allow soil surface to dry slightly between waterings. Ensure excellent drainage. No fertilizer needed; phosphorus-rich fertilizer may help flower production.

3

Flowering

4-6 weeks (spring into early summer)

Delicate flower spikes emerge from the rosette centers bearing tiny star-shaped pink or white flowers clustered in loose panicles

Maintain consistent moisture during flowering. Flowers bloom best with cooler temperatures (below 70°F). Deadheading extends blooming.

4

Post-Flowering & Seed Set

3-4 weeks

Flowers fade and small seed capsules form if flowers are not deadheaded; rosettes persist and may produce runners

Allow some flowers to set seed for natural propagation. Cut back flower stems. Continue moderate watering as temperatures warm.

5

Summer & Winter Dormancy

4-6 months per season

Rosettes remain compact and evergreen, becoming more colorful (bronze or red tinting) in cold winter conditions

Reduce watering significantly in winter in wet climates. Ensure drainage to prevent rot. No fertilization needed. Protect from excessive winter moisture with a gritty mulch.

Fun Facts
