Ceropegia linearis subsp. Woodii (String of hearts) 青叶一串心 (10cm pot) [CN]

Ceropegia linearis subsp. woodii, commonly known as String of Hearts, is a trailing succulent vine native to Southern Africa. This popular houseplant is adored for its delicate, heart-shaped leaves that are often variegated with silvery or greyish markings, giving it a striking, ornamental appearance. The plant produces small, tubular flowers that resemble lanterns, typically in shades of purple, and bloom intermittently. Known for its easy care and unique aesthetics, the String of Hearts is an ideal plant for hanging baskets, pots, or as a cascading feature in a garden.

Plant Care Guide

Light: String of Hearts thrives in bright, indirect light but can also tolerate some direct sunlight. In brighter light, the variegation in its leaves becomes more pronounced. Avoid placing it in too much direct sunlight, especially midday sun, as this can scorch the delicate leaves. A location with filtered light, such as near a window with sheer curtains, is perfect.

Water: This plant is drought-tolerant and prefers to dry out completely between waterings. Water the plant when the top 3-4 cm of soil feels dry to the touch. Overwatering can lead to root rot, so be sure the pot has good drainage to allow excess water to escape. During periods of slower growth or dormancy, reduce watering to avoid waterlogging the roots.

Soil: Well-draining, sandy, or cactus mix soil is ideal for String of Hearts. A light, gritty potting mix will prevent water retention around the roots and provide good aeration. Adding perlite or pumice can improve drainage, helping to keep the roots healthy and avoid rot.

Fertilising: Feed String of Hearts with a diluted, balanced liquid fertiliser during the growing season. This will promote healthy vine growth and vibrant foliage. Avoid over-fertilising, as this can encourage excessive leaf growth at the expense of the plant’s unique trailing habit. During dormancy, you can cut back on fertilising.

Pests: String of Hearts is generally pest-resistant but can occasionally attract pests such as aphids, mealybugs, or spider mites. Regularly inspect the undersides of leaves for signs of pests. If detected, treat with insecticidal soap or neem oil to keep the plant pest-free.

General Care: This plant is relatively low-maintenance and can tolerate neglect. However, to keep it healthy and looking its best, prune any leggy or damaged growth regularly. It’s also a good idea to occasionally clean the leaves with a soft cloth to remove dust and improve light absorption. Ensure the plant is not in a location where it is exposed to heavy rainfall or excessive humidity, as this can lead to root rot. String of Hearts can also benefit from occasional repotting to refresh the soil and promote continued growth.
