Seedling
2-3 weeksSmall rosettes of fine, linear, blue-green foliage emerge; plants are delicate and low-growing
Keep soil lightly moist but well-drained; provide bright light; thin seedlings to proper spacing early
Vegetative Expansion
4-6 weeksDense mat of foliage develops horizontally, spreading outward; no flowers yet, but plant builds vigor
Reduce watering frequency; ensure excellent drainage; avoid fertilizer high in nitrogen which delays flowering
Bud Formation
1-2 weeksFlower buds appear on short stems above the foliage mat; buds are small and tightly clustered
Maintain consistent moderate watering; deadhead spent buds to encourage more blooms; pinch back excessively tall stems if desired
Flowering
6-12 weeks (late spring through summer)Pink, fringed flowers bloom prolifically above the foliage, typically single or semi-double with sweet fragrance
Deadhead regularly to extend bloom; reduce watering slightly; support with small stakes if stems become leggy; enjoy fragrance
Dormancy/Winter
3-4 monthsFoliage persists but fades; plant enters slow-growth phase in cold months; evergreen in milder zones
Minimal watering; ensure drainage to prevent ice damage; no fertilizer; clean up dead leaves to prevent disease
