String of Dolphins
Dolphin Plant, or String of Dolphins (Senecio peregrinus), is a rare variety of trailing succulent that looks like a pod of leaping dolphins.
Like most succulents, Dolphin Plants thrive in well-draining soil. They can rot if over-watered, so be sure to use containers with drainage holes. Select a light, gritty soil like a cactus/succulent mix from a local garden center. You can also prevent rot by keeping the plant in a well-ventilated area.
