Seedling
3-4 weeksTiny seedlings emerge with cotyledons and first true leaves appear; very delicate with minimal growth
Keep soil constantly moist; provide high humidity; maintain cool temperatures (60-70°F); protect from direct sun and air movement
Vegetative Growth
4-6 weeksSmall rosette of heart-shaped leaves develops; plant remains low-growing with gradual leaf expansion
Maintain consistent moisture and humidity; feed with diluted liquid fertilizer every 2-3 weeks; ensure excellent air circulation to prevent fungal issues
Pre-Flowering
2-3 weeksPlant becomes more compact and sturdy; leaf growth slows as flower buds begin to form at base of plant
Reduce nitrogen slightly; maintain cool nighttime temperatures (50-60°F); continue consistent watering and humidity
Flowering
4-8 weeks (can extend with proper care)Delicate small violet or purple flowers emerge on short stems above foliage; blooms are fragrant and appear in succession
Maintain moisture and humidity; deadhead spent flowers to encourage continued blooming; reduce fertilizer frequency; avoid water on flowers
Seed Production & Decline
Ongoing through growing seasonIf not deadheaded, flowers develop seed capsules; plant energy shifts to seed production rather than continued flowering
Allow some flowers to set seed for propagation if desired; collect seed capsules when dry; or continue deadheading to promote blooming
