Ceropegia woodii, also popular as String of Hearts, is an evergreen African climber that makes a perfect hanging plant.

The String of Hearts is the most basic Ceropegia woodii plant native to South Africa, Southern Asia, and Australia.

The plant reaches about 12 feet in the wild but may only get a few feet long as a houseplant.
- Interestingly, it will grow inch-long, tube-shaped, pale magenta flowers every summer and fall when the conditions are right.
- Keep them in bright indirect light throughout the year and water every week in spring and summer.
- Similarly, choose small pots to allow the roots to be constricted to encourage longer vines.

Like Strings of hearts, it is non-toxic to pets and children.

- Water the plant every other week in spring and summer but strictly cut back in winter and let it bask in dropping temperatures (54°F).
- You must provide a combination of dry soil, shorter days, and cold nights during dormancy to encourage blooming in summer.
Ceropegia Linearis loves being potbound and requires transplanting every three years.
6. String of Hearts Orange River
As the name suggests, String of Heart Orange River is a unique sub-species that displays orange color beneath the leaves.
