Growth Stages

1

Seedling

2-3 weeks

Tiny green rosettes emerge with delicate rounded leaves showing hints of variegation

Keep soil lightly moist; provide bright light; avoid damping-off by ensuring excellent air circulation

2

Vegetative

3-4 weeks

Variegated foliage develops clearly with cream and green patterning; plant forms low mat 2-4 inches tall

Reduce watering frequency; transition to drier conditions; harden off seedlings gradually; minimal fertilizer needed

3

Pre-flowering

2-3 weeks

Flower buds form at stem tips; plant becomes more compact and dense

Maintain dry conditions; provide full sun; do not overwater as excessive moisture reduces flowering

4

Flowering

4-6 weeks

Abundant clusters of small white fragrant flowers appear above variegated foliage; creates striking contrast

Deadhead spent flowers to encourage continuous blooming; water sparingly; avoid overhead watering to prevent fungal issues

5

Post-flowering/Dormancy

Varies by season

Flowers fade; plant may rest in hot summers; foliage remains attractive through winter

Cut back after flowering if desired for tidiness; provide winter drainage to prevent rot; minimal water in dormancy
