Description
The String of Variegated Hearts is a unique succulent known for its delicate heart-shaped leaves, often marbled with shades of cream, green and pink, especially when exposed to morning sun. This trailing plant adds a whimsical touch to any indoor plant collection and is easy to care for, making it perfect for plant enthusiasts of all levels. Its tuberous roots store water, allowing it to tolerate periods of drought, provided it receives proper watering and drainage.
Growing Conditions
This plant thrives in bright but indirect light, avoiding direct harsh sun which can cause leaf burn. Because of its succulent nature, it benefits from a well-drained, airy substrate such as cactus or succulent mix enriched with 10% worm castings for balanced nutrition. Water when the top 2-3 inches of the soil is dry while reducing watering in cooler months.
Temperature and Humidity
Ideal temperatures range between 15°C and 27°C. While it tolerates average indoor humidity, keeping it above 40% improves leaf vibrancy. Protect it from cold drafts and temperatures below 10°C.
Propagation and Maintenance
Propagation is simple through stem cuttings or aerial tubers. Prune leggy vines to encourage fuller growth and increase plant density. Monitor for pests such as aphids or mealybugs and treat early with neem oil or plant-safe insecticides, following recommended South African guidelines.
Common Issues
The most frequent problem is root rot due to overwatering. Ensure good drainage and allow soil to dry between waterings. Adjust water pH if sensitivity to borehole water is noticed.
With proper care, the String of Variegated Hearts provides a lush, cascading display that’s both visually striking and easy to maintain, ideal for any indoor living space or greenhouse.
