Germination & Seedling
1-2 weeksTiny seedlings emerge with small oval cotyledons. True leaves develop hairy, gray-green texture characteristic of the species.
Keep soil consistently moist but not waterlogged during germination. Provide bright light once sprouted. Thin seedlings to proper spacing.
Vegetative Growth
3-6 weeksPlant develops dense, mat-forming foliage with hairy, lance-shaped leaves. Low spreading habit becomes evident.
Water moderately; allow drying between waterings. Fertilize lightly with balanced fertilizer every 4-6 weeks if desired. Pinch back to encourage bushier growth if needed.
Pre-flowering & Budding
1-2 weeksSmall flower buds form at branch tips. Plant may appear slightly taller and more upright as stems elongate.
Reduce nitrogen fertilizer to encourage flowering. Ensure adequate sunlight. Continue moderate watering.
Flowering
6-12 weeks or moreAbundant tiny white flowers (5-petaled) bloom in clusters. Flowering typically occurs in spring and early summer, sometimes continuing into fall.
Deadhead spent flowers to encourage prolonged blooming. Water at soil level to avoid wetting flowers. Maintain good air circulation.
Seed Set & Decline
4-8 weeksFlowers fade; seed pods (capsules) develop and mature. Plant may enter dormancy in peak summer heat or late fall depending on climate.
Allow some flowers to set seed for self-sowing, or deadhead all spent flowers. Reduce watering as plant slows growth. Cut back dead foliage in fall.
