Characteristics of String of Hearts
Trailing Vines with Heart-shaped Leaves
String of Hearts is characterized by its long, trailing vines adorned with small, succulent leaves shaped like hearts. These leaves are oppositely arranged along the vines, leaving the wiry stem visible.
The top sides of the leaves are typically dark green with silver veining or mottling, while the undersides add visual interest with their light grayish-green to purple coloration. In the wild, String of Hearts vines can reach impressive lengths of up to 13 feet, and they can achieve similar dimensions when grown indoors.
Lantern-shaped Flowers and Reproduction
This charming succulent also produces small, mauve and purple, lantern-shaped flowers with waxy petals. These flowers serve as pollinator traps for small flies, which are attracted inside but can escape once the flower’s downward-pointing hairs wither, ensuring pollination.
String of Hearts plants may bloom sporadically throughout the year when grown indoors. If pollination is successful, the flowers give way to long, thin seed pods that split open when dry, releasing seeds attached to fluffy tufts, similar to dandelion seeds.
Additionally, these plants can produce air tubers at nodes on the vines, resembling tiny potatoes, which can take root in the soil and eventually grow into woody stems.

Plant the Cutting: Plant the callused end of the cutting in a small pot filled with well-draining succulent or cactus soil. Make a small hole with your finger or a stick and insert the cutting about an inch deep.
Water Sparingly: Water the cutting lightly to settle the soil, but avoid overwatering. Keep the soil slightly moist but not waterlogged.
Provide Indirect Light: Place the pot in a location with bright, indirect light. Avoid direct sunlight, as it can scorch the cutting.
Monitor Growth: In a few weeks to a few months, your cutting should develop roots and start growing. Once it has established itself, you can treat it like a mature String of Hearts plant.
2. Water Propagation
Water propagation is a simple method that involves placing stem cuttings in water until they develop roots. It’s an excellent way to observe root growth.
How to do it:
Take Cuttings: Follow the same steps as for stem cuttings by selecting a healthy vine and making a clean cut just below a leaf node.
Place in Water: Fill a small container or jar with clean water and submerge the cut end of the vine, ensuring the leaf node is underwater. Use a clear container to monitor root growth easily.
Change Water Regularly: Change the water every few days to prevent stagnation and bacterial growth. Use room temperature water.
Observe Root Growth: In a few weeks, you should see roots developing from the submerged node. Once the roots are a few inches long, your cutting is ready for planting.
Plant in Soil: Plant the cutting in a small pot with well-draining succulent soil, following the steps mentioned earlier for stem cuttings.
3. Propagation by Tubers
String of Hearts can also produce small tubers, which are potato-like structures that form at nodes on the vines. These tubers can be removed and planted to grow new plants.
How to do it:
Locate Tubers: Look for small tubers at the nodes on the vines. They usually have a round shape and resemble tiny potatoes.
Carefully Remove Tubers: Gently detach the tubers from the parent plant using your fingers or small scissors. Ensure you don’t damage the parent plant or the tubers during this process.
Plant Tubers: Plant the tubers in small pots with well-draining succulent soil, burying them just below the soil’s surface.
Provide Adequate Light and Water: Place the pots in a location with bright, indirect light and water the soil lightly. Keep it consistently moist but not soaked.
Monitor Growth: With time, the tubers will develop into new String of Hearts plants, and you can treat them like mature plants.
