Seedling
2-3 weeksTiny seedlings with narrow cotyledons and first true leaves appearing 10-14 days after germination
Keep soil barely moist but never waterlogged. Provide bright light. Seedlings are prone to damping off; ensure excellent air circulation and avoid overwatering.
Vegetative Establishment
4-8 weeksYoung plant develops dense mat of small, narrow leaves forming a low cushion or mound
Maintain very dry conditions once roots establish. Gritty soil is essential. No fertilizer needed; rich soil encourages weak, disease-prone growth.
Budding
1-2 weeksTiny flower buds appear on short stems rising just above the foliage mat
Reduce watering further; extremely dry conditions promote flowering. Ensure full sun exposure.
Flowering
4-6 weeks (spring to early summer)Delicate blue, pink, or white flowers bloom on low stems, typically 1-2 inches tall, covering the plant in color
Maintain strict dry conditions. Deadhead spent flowers to encourage prolonged blooming. Avoid overhead watering.
Post-Bloom & Dormancy
6-8 monthsFoliage remains attractive year-round; plant may go semi-dormant or reduce growth in heat or winter
Continue dry watering regimen. Improve winter drainage with gravel mulch. Some dieback in winter is normal; do not prune heavily until spring growth resumes.
