To care for a String of Hearts plant, give it bright, indirect light, water sparingly (every 2–3 weeks in winter, weekly in summer), and use well-draining soil.
A mature String of Hearts (Ceropegia woodii) vine can stretch up to 12 feet (3.6 meters) with tiny heart-shaped leaves just ½ to ¾ inch (1.3–1.9 cm) wide. As of 2026, it’s still one of the trendiest trailing houseplants out there—thanks to its ability to handle drought and its gorgeous foliage.
Where does the String of Hearts come from originally?
The String of Hearts is native to the dry, rocky slopes of South Africa and Eswatini, where it grows in well-drained soils and partial shade under shrubs or rocky overhangs.
This plant’s natural home is in arid regions with seasonal droughts and warm temperatures. That tough environment shaped how we care for it today. Now, it’s grown all over the world as a houseplant because of its easygoing nature and those pretty cascading stems.
What are the basic care requirements for a String of Hearts?
Give it bright, indirect light, water every 2–3 weeks in winter or weekly in summer, and use a cactus or succulent soil mix for best results.

Why does the String of Hearts have such a unique name?
The String of Hearts gets its name from the paired, heart-shaped leaves that dangle from long, trailing stems—perfect for hanging baskets.
This plant belongs to the milkweed family (Asclepiadaceae), a group famous for some wild pollination tricks. Its tiny, tubular flowers even mimic the scent of female insects to lure pollinators into a pollen trap. The vine made its way into Western gardens in the early 1900s, became a Victorian conservatory favorite, and later rode the "boho plant" wave in the 2010s.
Indigenous to South Africa, the plant has been used in traditional medicine for centuries. Studies have looked into Ceropegia extracts for anti-inflammatory and antimicrobial properties, though research is still limited as of 2026. Its ability to survive drought reflects its tough origins, making it a plant-care underdog in many people’s eyes.
How much does a String of Hearts plant cost in 2026?
A 4-inch pot typically runs $10–$25 USD, while larger hanging specimens (vines over 2 feet) can cost $40–$75.
When shopping for one in 2026, prices vary based on stem length and leaf density. Common problems include:
- Yellowing leaves: Almost always a sign of overwatering. Check the roots—healthy ones are firm and white; rotten ones turn mushy and dark.
- Leggy growth: Usually means it’s not getting enough light. Move it to a brighter spot or add a grow light for 12–14 hours daily.
- Pests: Keep an eye out for mealybugs or spider mites, especially on new growth. Neem oil or insecticidal soap usually takes care of them.
If you’ve overwatered your plant, take it out of the pot, trim any black or mushy roots, and repot it in fresh, dry soil. Hold off on watering for at least a week. Once it’s established, this species actually thrives on a little neglect.
To propagate, snip a 4–6 inch stem just below a node, strip the bottom leaves, and place it in water or moist perlite. Roots usually show up in 3–4 weeks. Once rooted, plant it in well-draining soil and skip fertilizer for the first month.
As of 2026, String of Hearts plants are easy to find at garden centers, online plant shops, and even some grocery stores. The ASPCA lists it as non-toxic to pets, so it’s a great choice if you have cats or dogs. Pair it with other drought-tolerant plants like snake plants or pothos for a fuss-free display.
What’s the easiest way to propagate a String of Hearts?
The simplest method is to take a 4–6 inch stem cutting, remove the bottom leaves, and root it in water or moist perlite—roots usually appear in 3–4 weeks.
Clean scissors are a must. After cutting, just place the stem in water or perlite and wait. Honestly, this is one of the most beginner-friendly plants to share with friends. Once the roots are a couple inches long, plant it in well-draining soil and go easy on the fertilizer for the first month.
How do I fix yellow leaves on my String of Hearts?
Yellow leaves are almost always caused by overwatering, so check the roots—healthy ones are firm and white, while rotten ones are mushy and dark.
If you spot yellowing, it’s time to act fast. Remove the plant from its pot, trim any damaged roots, and repot it in fresh, dry soil. Don’t water it for at least a week—this plant bounces back surprisingly well once you cut off the rot.
Why is my String of Hearts growing leggy?
Leggy growth usually means the plant isn’t getting enough light—move it to a brighter spot or add a grow light for 12–14 hours daily.
This trailing vine stretches toward light, so if it looks stretched out and sparse, it’s begging for more brightness. A south-facing window works wonders, or you can supplement with a grow light. After the move, you’ll see fuller growth in just a few weeks.
How do I deal with pests on my String of Hearts?
Watch for mealybugs or spider mites, especially on new growth, and treat them with neem oil or insecticidal soap.
These pests love new growth, so check regularly. If you spot them, a quick spray of neem oil or insecticidal soap usually solves the problem. Prevention is key—keep the plant healthy and avoid overwatering, which can attract pests in the first place.
What type of soil works best for a String of Hearts?
Use a cactus or succulent soil mix, or make your own with perlite-heavy potting soil to ensure fast drainage.
This plant hates soggy soil, so drainage is everything. Skip dense, moisture-retentive mixes—your String of Hearts will thank you with healthy growth. If you’re unsure, add extra perlite or sand to improve drainage.
How often should I fertilize my String of Hearts?
Feed it monthly during the growing season (spring–summer) with a balanced liquid fertilizer diluted to half strength.
This plant isn’t a heavy feeder, so less is more. Over-fertilizing can damage the roots, so stick to the half-strength rule. In fall and winter, you can skip fertilizing entirely—it’s resting during those months.
Can I grow a String of Hearts outdoors?
You can grow it outdoors in warm climates (USDA zones 10–11), but bring it inside if temperatures drop below 10°C (50°F).
In its natural habitat, it thrives in dry, rocky spots, but most of us keep it indoors. If you live where winters are mild, you can place it outside in bright, indirect light. Just remember to bring it in before the cold hits.
Is the String of Hearts toxic to pets?
No, the String of Hearts is considered non-toxic to pets according to the ASPCA.
That makes it a safe pick for homes with cats or dogs. Still, it’s always a good idea to keep plants out of reach—some pets might chew leaves just because they’re curious. If you’re worried, pair it with other pet-friendly plants like spider plants or Boston ferns.
What’s the best way to revive an overwatered String of Hearts?
Remove it from the pot, trim any black or mushy roots, repot in fresh, dry soil, and avoid watering for at least a week.
Overwatering is the fastest way to kill this plant, so act quickly. After repotting, give it time to recover—this species actually prefers a little neglect once it’s back on track. You’ll see new growth in a few weeks if you’ve caught the problem early enough.
How do I encourage bushier growth in my String of Hearts?
Give it bright, indirect light and occasional pruning to trim long stems and encourage branching.
This plant naturally trails, but you can shape it with a little trimming. Pinch back the tips of leggy stems to promote bushier growth. A sunny spot also helps—it’ll fill out faster with more light.
What temperature range is ideal for a String of Hearts?
Keep it between 18–27°C (65–80°F) and avoid temperatures below 10°C (50°F).
This plant loves warmth but can handle average indoor temps. Just keep it away from drafts, heaters, or sudden temperature swings—it’s not a fan of surprises. If you’re comfortable, your String of Hearts probably is too.
