Growth Stages
Establishment
2-4 weeksYoung plant adapts to its environment; minimal new growth visible
Keep soil barely moist; place in bright, indirect light. Avoid moving frequently. New growth should emerge within 2-4 weeks.
Active Growth
Several months (spring-summer)Stems elongate and new pearl-like leaves appear along the length of the stems
Maintain bright light and well-draining soil. Water only when soil is completely dry. Stems may reach 12+ inches long.
Flowering
Several weeksSmall clusters of white flowers with delicate stamens appear along the stems; flowers emit a pleasant cinnamon fragrance
Flowering typically occurs in summer. Continue regular care. Do not disturb flowering stems unnecessarily.
Dormancy
Fall-winter (3-4 months)Growth slows significantly; plant enters rest period with minimal new leaf development
Reduce watering to once every 3-4 weeks or when soil is bone dry. Provide bright light but lower temperatures if possible (50-60°F).
Propagation-Ready
OngoingMature stems can be used to propagate new plants; aerial roots may begin forming on stem segments
Trim 2-3 inch stem segments. Let cuttings air-dry for 1-2 days, then place on dry soil to root. Mist lightly after 2-3 weeks.

Fun Facts
- 🌱 String of pearls is native to southwestern Africa (Namibia and South Africa) where it grows as a ground cover in arid, rocky terrain.
- 🌱 The pearl-like leaves are actually modified stems (cladodes) that store water, allowing the plant to survive extended periods without rainfall—a key adaptation to its desert habitat.
- 🌱 The plant can be easily propagated by simply placing individual stem segments on soil; new plants will develop roots within 2-3 weeks without requiring water initially, showcasing remarkable reproductive efficiency.
