Seed Germination
3-4 weeks for germination after cold stratificationTiny seedlings emerge with first true leaves appearing after stratification period (4-6 weeks cold period required).
Provide consistent moisture, bright indirect light, cool temperatures (50-60°F), and high humidity. Use well-draining seed compost. Seeds are very small—sow on surface and mist gently.
Seedling & Rosette Development
6-12 monthsSmall rosettes of rounded, glossy evergreen leaves form; plant remains low and compact.
Maintain cool, humid conditions. Avoid heat stress. Keep soil lightly moist. Provide bright, indirect light. Careful watering to prevent damping off.
Vegetative Growth
12-24 monthsEstablished plant produces dense mounds of basal foliage with clearly visible round leaves; plant gains diameter.
Continue cool conditions. Feed lightly with dilute, balanced fertilizer. Ensure excellent drainage to prevent rot. Increase air circulation.
Flowering
4-6 weeksDelicate 1-4 inch stems emerge with nodding, fringed bell-shaped flowers in shades of lavender, pink, or white, typically appearing in March-April.
Do not fertilize during flowering as excess nitrogen reduces blooms. Maintain cool temperatures and moderate moisture. Protect from late frost. Deadhead spent flowers to encourage reflowering.
Seed Development & Rest
6-8 weeks through summer dormancyAfter flowering, small seed capsules develop; plant enters summer dormancy period, requiring reduced water and cooler conditions.
Allow some flowers to set seed if desired. Reduce watering gradually. Provide cool, shaded conditions during dormancy. Mulch lightly to retain moisture without promoting rot.
