Botanical Name: Ceropegia linearis woodii
Whether you call it Rosary Vine or String of Hearts, you'll be captivated by this charming house plant.
Pairs of heart-shaped leaves grow about every 3 in (8 cm) along the slender stems. Decorative all on their own, the leaves are splotched with a lacy pattern of white on the top and are purple underneath.
Display Ceropegia in a hanging basket to show off those long, heart-studded vines.
Propagate your plant. Small tubers sometimes grow along the stems, causing the stems to branch out. You can remove the tubers anytime and set them on the surface of the soil to grow more plants in the same pot.
Prune it back when Rosary Vine starts to look leggy. Propagating the stem cuttings by inserting them back in the soil will give a fuller display that's lush with leaves.
Repot in spring when it gets crowded, moving to a pot only 1-2 inches (2.5-5 cm) bigger. This vining plant grows from 2-inch (5 cm) tubers. Place them on the surface of the soil and they'll root quickly. Use a sandy mix and a pot with a drainage hole to avoid soggy soil, which can cause the tubers to rot.
Something bugging your houseplant? Rosary Vine seems to shrug off pests, but watch for webbing between leaves and stems -- a tell-tale sign of spider mites. These tiny pests are attracted to plants, especially during the winter months when indoor air can become extremely dry. Treat any infestation immediately. Raising the humidity around your houseplant can help.
Is Ceropegia woodii poisonous? No. It's not toxic, but I can see how its long, dangling leaves may appeal to playful cats and dogs. That's another good reason to hang it up, away from curious pets.
This carefree classic beauty was once an extremely popular indoor plant, but not as common these days. Perhaps it has fallen out of favor because it is so easy to grow? Somehow easy-care plants get less respect. If you come across this beautiful succulent vine, buy it. It's long-lived and easy to propagate for more plants.
You may find rosary vine for sale at online nurseries or at your local garden center. It is usually labeled by its genus and subspecies names, Ceropegia woodii.
Origin: South Africa
Height: Trails to 3 ft (90 cm) or more
Light: Keep your plant in bright light (with some direct sun) for best color and plenty of leaves. Long spaces between leaves are a sign it's not getting enough sunlight.
Water: Keep the soil lightly moist in spring and summer. Water sparingly in fall and winter, when growth is slow. A semi-succulent, this plant is more tolerant of dry soil than wet. In fact, one sure-fire way to kill Rosary Vine is to over-water. Use a pot with a drainage hole to prevent soggy soil, which can lead to stem rot or root rot.
Humidity: Moderate (around 45% relative humidity). If indoor air is dry, use one of these easy ways to increase humidity for your houseplant.
Temperature: Normal room temperatures (65-80°F/18-27°C). Don't expose this warm-natured plant to temps below 55°F/13°C.
Soil: Mix 1 part good-quality, all-purpose potting mix and 1 part sand or perlite for fast drainage. Cactus potting mix works beautifully to give Rosary Vine the fast drainage it needs.
Fertilizer: Feed monthly in spring and summer with water-soluble fertilizer. Don't feed in fall and winter when growth is slower.
Propagation: Take stem tip cuttings and insert cut ends in moist soil. Or cut off stem tubers and place them on the surface of the soil, where they'll root quickly.
