String of Hearts Origin & Varieties
The string of hearts is a semi-succulent native to South Africa, Swaziland, and Zimbabwe. It has become a popular hanging houseplant thanks to its iconic, heart-shaped leaves.
The scientific name of this plant is Ceropegia woodii. The variegated string of hearts is sometimes referred to by other names. Another common name for it is the Rosary Vine, because of the little tubers that grow on the base of the leaves. These tubers resemble the beads of a rosary. Other names for it are Chain of Hearts and Hearts Entangled.
There are two varieties of the string of hearts – the standard and the variegated. The big difference between these two cultivars is only a slight color variation. The variegated cultivar has light purple at the edges of its leaves that goes onto the back. This purple is the only identifier for the two different cultivars.
String of Hearts Plant Care Summary
- Temperature: The string of hearts prefers warm temperatures. It should not be allowed to get cold, as this can damage the plant.
- Light: The plant does best in bright, indirect light but can also tolerate some direct sun.
- Water: The plant should be watered when the soil is dry to the touch. Over-watering can lead to root rot.
- Soil: The string of hearts prefers a well-draining potting mix.
- Fertilizer: The plant should be fertilized every two weeks during the growing season.
- Pruning: The plant can be pruned to control its growth. Pruning also encourages fuller growth.
- Propagation: The plant can be propagated from stem cuttings.
- Toxicity: The string of hearts is not considered to be a poisonous plant and is pet friendly.
The variegated string of hearts can be identified by its heart-shaped leaves of pink, cream, and green. They drape down along the purple and wiry stem as they grow.
This houseplant is a trailing vine succulent, which means you can easily find a place to hang it neatly in your home. And it’s status as an evergreen succulent means you can treat it similarly to one.
Both the standard and variegated cultivars have a combination of mottled green and silvery grey leaves. However, the variegated cultivar is distinguished by a light purple hue on the edges of the surface and onto the back of the leaf.
This trailing plant can grow up to 10 feet long in the right conditions. However, when kept as a houseplant it is unlikely to grow past 2-3 feet. You may also need to cut back the stems to promote new, fuller growth.
Variegated String of Hearts Care Overview
The Ceropegia woodii thrives in filtered sunlight and warm temperatures. If you keep it moderately watered and fed a few times each year, you should expect to see decent growth and perhaps a tiny flower or two.
The string of hearts can be grown in an environment with a mixture of partial sun and partial shade. These plants prefer a bright, warm space, but prefer filtered sunlight over intense, direct light. An optimum location is a spot near any south, southwest, or west-facing window. This will give the plant plenty of strong, indirect sunlight that will not fry the delicate leaves.
Too little light will result in less variegation in the leaves. But too much light, especially direct sunlight, can burn your plant. And just the right amount of light will help the heart-shaped leaves grow closer together on the vines.
This plant is an evergreen type of succulent, which means it acts similar to other succulents. It has the regular requirements of a succulent. Some people recommend the soak and dry method, which means watering well and then letting the soil dry out again.
You should generally let the top 2 inches dry out between each watering. And after watering, you should not let it sit in water. Over-watering can cause the roots to rot.
This plant does not go fully dormant in the winter, but it does need much less water. In general, the leaves will look and feel plump when they are well-watered. When they need water, leaves will be spongy to the touch.
Due to the delicate nature of the roots, the string of hearts needs a light soil mixture to thrive. Their roots need space to grow and should never be packed in tight, closed soils.
A specialty soil is optimal, such as a combination of succulent and cacti mixtures. However, regular potting soil is also fine as long as you add some sand to keep the soil loose. Sand will also provide great drainage, which is vital to the success of your string of hearts.
Location and Temperature Needs
When planted outside, the variegated string of hearts is a Zone 11a plant. It is native to a warm climate and is therefore not a cold-hardy plant. If you live in a zone that gets colder than 40 degrees Fahrenheit, it is recommended that you plant the string of hearts in a container that can be brought inside for the fall and winter.
An optimal temperature for this plant during the day is between 65 degrees Fahrenheit and 90 degrees Fahrenheit. Nighttime temperatures should never dip below 40 degrees Fahrenheit.
If you do live in a warmer climate, you can plant this comfortably in a garden. You should ensure that wherever you place it that it can receive 3 to 4 hours of sunlight each day. When kept as a houseplant, the string of hearts receives the best indirect light in a location near a southern-facing window.
Special Requirements for the Variegated String of Hearts
A string of hearts is a somewhat dainty plant. You should be certain to remember to monitor other aspects of its environment and conditions beyond water, light, and soil to ensure optimal care. These requirements include humidity, air circulation, water quality, and feeding.
The string of hearts is not a plant that needs high humidity. In fact, it will be fine in most house environments as long as you follow the other care requirements.
Ventilation is a vital component of a happy string of hearts. It has thin and wiry stems, which can be easily damaged, which means the right ventilation should be a priority when placed inside.
There are no extensive issues with water quality for this plant. You can use tap water successfully in most cases. However, you should avoid using very cold water. Instead, water a string of hearts with tepid or room temperature water to avoid shocking the delicate roots.
Plant Feeding Requirements
If you want to keep your plant thriving and healthy year after year, you can use almost any houseplant fertilizer during its regular growing season.
From spring to midsummer, a fertilizer will provide extra nutrition and support. Stop feeding your string of hearts, however, in midsummer to allow it time to prepare for its semi-dormancy in the fall and winter.

Taking a stem cutting is a simple process and only requires a little bit of time before you can plant a new string of hearts. You need to snip a small portion of the stem, allow it to form a callous at the end, and then plant in well-draining soil.
The string of hearts also has a unique feature that is useful in propagation. The small tubers that form on the stems can be removed from a parent plant and pressed directly into the soil. A detached tuber will quickly take root.
And if you are looking to start from scratch, you can grow a string of hearts from seed. You should plant in fall, and only outside if you live a zone above 9a. In cooler locations, it is always advised that you start your seedlings inside under a grow light to promote optimum propagation.
The string of hearts grows fairly fast, which means that you sometimes need to re-plant them to ensure the best living environment.
Generally, the best time to repot large, parent plants is the springtime. Springtime is also a great time to take stem cuttings for the propagation of new plants.
The Ceropegia woodii variegata is prone to the same issues as many houseplants. Pests such as aphids and mealybugs can occur, but you only need to follow the usual guidelines to get rid of them without harming your plant.
