Seedling
2-3 weeksTiny seedlings emerge with simple cotyledons; very delicate and small initially
Keep soil barely moist; provide bright light; avoid damping off by ensuring excellent drainage and air circulation
Vegetative
3-4 weeksPlant develops multiple stems and small opposite leaves; compact, bushy form emerges
Gradually reduce watering; pinch back if needed for bushiness; full sun encourages compact growth
Flowering
4-8 weeks or longerDistinctive small flowers appear in leaf axils; flowers are often inconspicuous but surrounded by colorful cyathia (cup-like structures)
Reduce nitrogen fertilizer to encourage flowering; maintain dry conditions; deadhead spent flowers if desired
Seed Development
2-4 weeksSmall three-chambered seed capsules develop and mature; seeds disperse when ripe
Allow plants to self-seed if desired, or collect seed capsules before they split open
Dormancy/Decline
Varies by climate and speciesPlants may die back in cold climates or persist as dormant perennials in warm zones
Protect tender species over winter with mulch or move indoors; allow hardy species to naturally decline
