Senecio rowleyanus 'String of Pearls'

String of pearls is a quirky and cascading succulent, with bright green round leaves. Originating from southern Africa, where they grow as a trailing groundcover over rock outcroppings, each stem can potentially reach several feet in length. The unique, pearl-shaped leaves are an adaptation to survive drought conditions in their native desert home, and each leaf has a crescent-shaped “window” that allows light to enter so photosynthesis can proceed more readily. String of pearls prefers bright, indirect light, to avoid sunburning, and a room without chilly drafts, as cold air can cause leaves to drop. The shallow root systems of this plant predisposes it to rot, so fast-draining soil in a pot with sufficient drainage is critical. It is also important not to let any of the “pearls” rest on wet soil for too long. Keeping the soil at the same level as the top of the pot, to allow for airflow around the leaves, can go a long way toward eliminating rot issues. Water thoroughly but only when the soil is completely dry, and even more infrequently during the winter months, as the plant shifts into dormancy. A happy plant will grace you with tiny white flowers that resemble pom-poms and smell like cinnamon. To encourage spring flowers, cut back on water and keep the plant in cooler, but not freezing or drafty temperatures (around 60 degrees) during the winter months. It is important to note that the sap of the plant can cause skin irritation, or vomiting if ingested, so wash your hands after handling and use caution around small children or curious pets that may wish to take a bite!
