Propagule/Cutting
3-5 weeksIndividual leaves or small rosette fragments ready for propagation
Allow cuttings to callus for 3-5 days before placing on dry soil. Keep in bright, indirect light until roots form (2-3 weeks).
Establishment
4-6 weeksYoung rosettes with developing root systems and new growth
Provide bright light and minimal water. Begin very light watering once roots are visible. No fertilizer needed.
Vegetative Growth
2-3 monthsEstablished rosettes expanding with dense needle-like foliage, blue-green coloring develops
Water moderately during growing season (spring-early summer). Foliage color intensifies with full sun and slight drought stress. Minimal fertilizing needed.
Flowering
4-6 weeksSmall pink or white star-shaped flowers appear on inflorescences above the foliage
Continue regular watering during bloom. Flowers attract pollinators. Deadheading extends blooming but is optional.
Winter Dormancy
3-4 monthsGrowth slows or stops; foliage may deepen in color; plant becomes increasingly cold-hardy
Reduce watering to minimal levels. Do not fertilize. Excellent drainage is critical to prevent rot during dormancy. In very wet climates, move containers under cover.

Fun Facts
- 🌱 Broken Needle Sedum is one of the most cold-hardy sedums, surviving temperatures down to -30°F (-34°C) in zone 3, making it one of the hardiest succulent species available.
- 🌱 Individual sedum leaves can regenerate entire new plants; a single fallen leaf dropped on moist soil can develop roots and grow into a complete rosette within weeks.
- 🌱 The plant's needle-like foliage is an adaptation to dry conditions, reducing surface area to minimize water loss while maximizing structural efficiency.
