Seedling
3-4 weeksTiny rosettes emerge with fine, needle-like foliage. Very delicate and requires careful moisture management.
Keep soil consistently moist but not waterlogged. Provide bright, indirect light. Avoid damping off by ensuring good air circulation.
Rosette Development
6-12 weeksCompact cushion of deeply lobed, often reddish-tinged foliage forms. Plant gradually thickens and becomes more robust.
Maintain moderate moisture. Gradually acclimate to brighter light. Ensure gritty soil composition prevents rot. No fertilizer needed; use lean soil.
Flowering
4-8 weeks (spring to early summer)Delicate stems emerge from rosette center bearing clusters of small, deep crimson-red flowers. Blooms are typically star-shaped and appear above foliage.
Maintain consistent watering without waterlogging. Deadhead spent flowers to encourage extended blooming. Provide full sun for best color intensity.
Seed Development & Summer Rest
6-8 weeksAfter flowering, small seed capsules form. Plant transitions into semi-dormant period in summer heat.
Reduce watering significantly in summer. Provide afternoon shade in hot climates (zones 6-7). Allow seed pods to mature if collecting seed.
Winter Dormancy
12-16 weeksFoliage persists in low-growing rosette form, often deepening in color. Plant enters dormancy or semi-dormancy.
Minimize watering; water only if soil becomes bone-dry. Protect from excessive winter moisture and standing water. Ensure superior drainage. Remove any dead foliage to prevent fungal issues.
