The most popular string succulents (String of Hearts, String of Pearls, String of Bananas, String of Dolphins), native to South Africa, have gorgeous shape and versatility. The stems can grow up to 3 feet (90cm) long. They look great in hanging baskets a few feet up, or trailing as vines in a container. When cut, the stems will split into two or more and keep on growing. String Succulents are easy to care for. Provide bright, indirect light. Water when the top inch of the soil is dry. Water more in the summer months and less in winter. Provide a well-draining soil. They also need protection from frost.
