Seed & Germination
3-4 weeksTiny seeds remain dormant or germinate slowly; seedlings are delicate with fine cotyledons.
Cold stratify seeds 4-6 weeks in moist sand; sow on surface or barely covered. Keep soil moist but not soggy. Germination can take 2-3 weeks.
Seedling & Establishment
4-6 weeksYoung plants develop their first true leaves and begin forming compact growth patterns. Growth is slow initially.
Provide good air circulation to prevent damping off. Maintain consistent moisture without waterlogging. Keep in cool conditions if possible.
Vegetative Growth
8-12 weeks (or overwinter)Plant develops dense, cushion-like mound of linear, gray-green foliage. No flowers yet, but structure is forming.
Allow to establish without fertilizer or minimal feeding. Ensure excellent drainage. May not flower in first year from seed.
Flowering
12-16 weeks (June/July through October/November)Abundant small pink to magenta five-petaled flowers emerge on short stems above the foliage. Continuous blooming from mid-summer through fall.
Deadhead spent flowers to encourage continuous blooming. Reduce watering slightly if weather is very wet. Do not fertilize heavily as this encourages foliage over flowers.
Dormancy & Winter Rest
4-6 monthsFoliage persists but growth slows dramatically in cold months. Plant remains evergreen in many zones.
Ensure excellent drainage to prevent winter rot, especially in wet climates. No supplemental water needed. Mulch lightly with grit rather than organic matter.
