Offset/Propagule
1-2 weeks to callus, 2-4 weeks to rootSmall individual rosettes detached from mother plant, 0.5-1 inch diameter
Allow cut ends to callus for 3-5 days before planting; keep soil barely moist until roots form (2-3 weeks)
Young Rosette Establishment
4-8 monthsSingle rosettes expanding slowly, 1-3 inches across, establishing root system
Minimal watering; ensure excellent drainage; full sun encourages compact growth and red coloration; protect from excessive winter moisture in humid climates
Mature Rosette
Ongoing; 1-2+ years of vegetative growthFull-sized rosette 2-4 inches in diameter with dense, tightly-packed blood-red leaves; ready to flower and produce offsets
Water sparingly during active growth (spring-early summer); maintain full sun exposure; no fertilizer needed; allow offsets to develop around base
Flowering
4-6 weeks (late spring through summer)Central rosette produces elongated flowering stem 4-8 inches tall with star-shaped pink, red, or magenta flowers; non-terminal inflorescence
Flowering does not kill rosette; allow blooms to complete; cut flowering stem after flowers fade; continue regular care
Offset Production & Spread
Continuous from year 2 onwardMature rosettes and flowering plants produce multiple small offsets (chicks) around the base; colony gradually expands
Allow offsets to remain attached until 1-2 inches diameter, then gently remove and propagate separately; or leave attached to create dense mats

Harvest Tips
Sempervivum is ornamental; 'harvest' by gently removing mature offsets when 1-2 inches in diameter, typically starting in late spring/early summer. Allow cut ends to air-dry 3-5 days before replanting. Flowering rosettes do not die after blooming; remove spent flower stalks at base for neatness.
Fun Facts
- 🌱 'Bloodstone' gets its name from the deep blood-red pigmentation of its leaves, which intensifies during cold snaps and with increased UV exposure—making it more colorful in autumn and winter.
- 🌱 Sempervivum means 'forever-living' in Latin, referencing its remarkable hardiness and ability to survive and propagate in extreme conditions with minimal water.
- 🌱 This cultivar is monocarpic at the individual rosette level; flowering rosettes do not die immediately but continue to produce offsets, making it effectively polycarpic at the colony level.
