The String of Hearts (Ceropegia woodii) is a trailing succulent-like plant native to South Africa. The delicate heart-shaped foliage and slender vines can reach up to 12' long in its natural environment, and has earned this plant many nicknames, including Rosary Vine and Sweetheart Vine.
Place your String of Hearts where it can receive plenty of bright indirect light. Small doses of direct sun are good, however too much direct sun can scorch the leaves. This plant is not suitable for lower light environments. A few feet removed from a southern or western-facing window is ideal, or directly in a northern or eastern-facing window will also suffice.
