About the String of Pearls
String of Pearls (Senecio rowleyanus, now Curio rowleyanus) is native to the dry regions of southwest Africa, where it creeps along the ground in the partial shade of rocks and other plants. Its trailing stems bear spherical, bead-like leaves with a translucent window stripe that allows light to reach the interior chlorophyll -- an adaptation for water storage and photosynthetic efficiency in arid habitats. In cultivation, cascading strands can trail over 60 cm, creating a striking waterfall effect from a hanging planter or high shelf.
Origin: South Africa
Care Tips
Provide bright indirect light with some morning direct sun; insufficient light causes the pearls to elongate and lose their round shape. Plant in a fast-draining succulent mix with extra perlite. Water deeply but infrequently, allowing the soil to dry completely -- roughly every 10-14 days in summer and less in winter. Overwatering causes the pearls to burst and stems to rot. Average to low humidity is ideal. Feed monthly during the growing season with a diluted succulent fertilizer. Propagate by laying stem cuttings on moist soil and pinning at the nodes.
