Ceropegia woodii is a flowering plant in the dogbane family Apocynaceae, native to South Africa, Eswatini and Zimbabwe. It is sometimes treated as a subspecies of the related Ceropegia linearis, as C. linearis subsp. woodii.[1] Common names include chain of hearts, collar of hearts, string of hearts, rosary vine, hearts-on-a-string, and sweetheart vine.Very similar to your regular String of Hearts but the leaf shape and coloring is slightly different. The Silver Dollar SOH has wider more “Silver Dollar” shaped leaves and a silvery tint to it with pink/purple under-leaves. Subtle, but super cute and harder to find.
It is an evergreen succulent trailing vine that grows to 10 centimetres (3.9 in) in height and spreads to reach up to 2–4 metres (6 ft 7 in – 13 ft 1 in) in length. Its leaves are shaped like hearts, about 1–2 cm wide and long. When exposed to sufficient light they have a deep green colour; under insufficient lighting the leaves are pale green. With age it develops a woody caudex at its base. The roots, and occasionally the stems, will often develop tubers. On the stems these tubers form at nodes and are likely the reason for the common name of rosary vine.
In general, the flower form is similar to those of other Ceropegia species. The corolla grows to 3 cm in length and is a mixed colouring of off-white and pale magenta. The five petals are a deeper purple.
Light: Bright indirect light will keep your string of hearts growing quickly and colors vibrant, growth rate will significantly slow if not given enough light.
Water: Although the String of Hearts is a succulent, it likes to have more frequent watering than other succulents. Let your String of Hearts dry out between watering then water deep. If you notice the leaves swelling, this may be a sign of too much water. These can be susceptible to root rot so do not leave them in standing water.
Humidity: Ceropegia woodii do not need any extra humidity. Normal indoor environment will keep them happy.
