Germination & Seedling
2-3 weeksSeeds sprout within 7-14 days with light exposure. Tiny seedlings emerge with first true leaves appearing shortly after.
Keep soil consistently moist but not waterlogged. Provide bright light. Do not cover seeds. Thin seedlings to proper spacing.
Vegetative Growth
3-4 weeksPlant develops spreading stems and small oval leaves, creating a dense mat close to the ground. Growth expands outward rapidly.
Maintain moderate moisture. Reduce watering frequency. Pinch back growth if contained size is desired. Full sun promotes compact growth.
Flowering
4-8 weeksTiny, inconspicuous greenish or reddish flowers appear in leaf axils and at branch tips. Blooms are often overlooked due to small size.
Continue regular watering and full sun exposure. Flowers attract minimal pollinator attention. Allow some flowers to set seed if desired.
Seed Production & Maturation
2-3 weeks to full maturitySmall seed capsules develop where flowers were. Plant may begin to slow growth or decline in cooler weather if grown as annual.
Reduce water further. Allow seeds to mature on plant if self-seeding is desired. In perennial zones, plant will persist through winter.
Dormancy/Winter
2-4 months (seasonal)In zones 9-10, growth slows significantly. In zones 11-12, plant may remain semi-active. Foliage may turn reddish or bronze.
Minimize water in winter months. Plant may appear nearly dormant. Resume normal care in spring as temperatures warm.
