With their cascading vines and distinctive heart-shaped leaves string of hearts have captivated the hearts of plant lovers worldwide. But there is often confusion around whether these striking trailing plants are actually succulents. In this article we’ll examine the succulent qualities of string of hearts and what makes their care and adaptations unique.
First, let’s cover some background on these beautiful hanging plants. String of hearts, also known by their scientific name Ceropegia woodii, are native to southern Africa. They likely earned the common name “string of hearts” due to their heart-shaped foliage that emerges along vining stems.
There are over 200 Ceropegia species, but C. woodii is the most common houseplant variety. It features delicate green leaves with silver variegation that resemble little dangling hearts. With proper care, the vines can cascade up to 13 feet long, making this plant perfect for hanging baskets.

Are String of Hearts Succulents?
So are these charming trailing plants actually succulents? The short answer is yes, string of hearts are considered a type of succulent. They belong to the extensive Apocynaceae plant family that contains many succulent species.
String of hearts exhibit several key traits that classify them as succulents, including:
- Fleshy, plump leaves and stems for storing water
- Drought tolerance and ability to thrive in arid conditions
- Minimal watering needs compared to other houseplants
- Slow growth habit
However, string of hearts have some distinct differences from more stereotypical succulents like aloe or echeveria. They lack the same level of thickness and moisture retention in their leaves that other succulents have.
So while string of hearts are technically succulents, they are on the more delicate end of the spectrum compared to their desert-loving cousins. Their subtropical origins and vining growth habit also set them apart from most common succulents.
Unique Adaptations of String of Hearts
The string of hearts’ native environment in South Africa holds clues to understanding its status as a subtropical succulent vine different from traditional arid succulents.
In the wild, string of hearts grow in semi-arid conditions often near subtropical forests. They commonly climb up trees and rocks. This vining habit allows them to climb towards sunlight in shady forest understories.
The vines and leaves adapted to store just enough water to survive seasonal droughts. But string of hearts also had to adjust to more humidity and frequent rainfall than desert succulents. This required balancing water storage with an openness to absorb moisture when available.
Additionally, string of hearts evolved to be evergreen in their native habitat unlike desert succulents that go dormant. They adapted to continuously photosynthesize and produce energy from the sun year-round thanks to warmer winters.
Understanding the native environment helps explain why string of hearts perform differently than a stereotypical succulent like a cactus or aloe. They contain some standard succulent adaptations like water storage and drought resistance. But as tropical subtropical vines, they also diverge from classic succulent features.
Caring for String of Hearts as Succulents
The succulent properties of string of hearts influence their care needs. Here are some key tips for growing string of hearts as succulents:
- Allow soil to partially dry out between waterings. Fully drying can cause leaf loss.
- Provide bright, indirect sunlight to fuel growth. But avoid intense direct light that can sunburn leaves.
- Use a fast-draining potting mix amended with additional perlite or sand to prevent moisture buildup.
- Limit fertilizer to prevent excessive, weak growth. They are light feeders needing infrequent dilute fertilizer.
- Watch for pests like mealybugs or spider mites that frequently attack succulents. Isolate and treat infestations early.
- Mist leaves occasionally to provide humidity. But take care not to overdo it and risk rotting.
- Repot every 2-3 years as vine growth expands. But avoid oversized pots that retain too much moisture.
The key for string of hearts care is striking a balance. Meet their needs as succulents for adequate sunlight, dry periods between watering, and fast-draining soil. But avoid overdoing arid conditions or you risk leaf loss. Recognize their subtropical adaptions and provide higher humidity and more frequent watering compared to desert succulents.
With the proper care tailored to their unique nature as subtropical succulent vines, your string of hearts will thrive and cascade beautifully on vines up to 13 feet long!
Differences Between String of Hearts and Other Common Succulents
To understand the specialized care string of hearts need, it helps to examine how they differ from standard succulents grown as houseplants:
- Water needs: Require more frequent watering compared to arid succulents. Extended drought causes leaf loss.
- Sunlight preferences: Dislike intense, direct light that burns their thin leaves. Prefer moderately bright indirect sun.
- Ideal temperatures: Tolerate a wider temperature range between 50-80°F compared to many succulents.
- Humidity: Appreciate 40-50% humidity. Avoid very dry air that dehydrates the vines.
- Soil: Need moisture retention but also drainage to prevent rotting. A balance of peat and perlite/sand.
- Dormancy: Do not have a strong dormancy period and slow growth in winter like some succulents.
- Growth habit: Vine and grow as an evergreen epiphyte unlike most rosette-forming succulents.
- Leaf structure: Leaves are dainty and less thickly succulent than those adapted to deserts.
Accommodating these differences allows string of hearts to survive as houseplant succulents. Match their conditions to their tropical subtropical origins, not the desert habitats of other succulents.
Signs of Unhealthy String of Hearts Plants
When their needs are not met, string of hearts may show these signs of decline:
- Leaf curling and wrinkling – Often caused by insufficient watering. Slowly increase water.
- Leaf yellowing or loss – Can signal overwatering. Allow more time between waterings for soil to dry.
- Elongated, leggy stems – Insufficient sunlight causes stems to overly stretch for light.
- Wilting – May indicate underwatering or damaged roots from overwatering. Assess watering regimen.
- Failure of cuttings to root – Wet soil from overwatering rots freshly propagated plants. Use well-draining mix.
- Pests like mealybugs, mites, or aphids – Isolate and apply insecticidal soap.
Catching issues early and adjusting care is key to avoid decline. Learn the signs of underwatering vs. overwatering which commonly impact these subtropical succulents.
Caring for the Unique Nature of String of Hearts
While string of hearts belong to the succulent family, recognizing their differences from arid succulents like cacti helps explain their more specialized care needs. Adapting to subtropical Africa as vining epiphytes shaped their moisture requirements, sunlight preferences, ideal temperatures, and growth habits.
Accommodate their need for bright indirect light, occasional misting, moderate but not excessive water, and warmth. With a basic understanding of their background as tropical subtropical succulent vines, you can help your trailing string of hearts flourish indoors. Showcase their beautiful heart-shaped leaves and gracefully dangling vines!
Should we grow String of Hearts Indoors or Outdoors?
String of Hearts can be grown both indoors and outdoors, but choosing the best environment depends on your local climate and the plant’s specific care requirements. Indoors, String of Hearts thrives when placed in a spot that receives bright, indirect sunlight. A south or east-facing window is ideal, where it can enjoy filtered light for several hours a day without the risk of scorching. Indoor conditions offer the advantage of consistent temperature and humidity, supporting steady growth throughout the year. This makes it perfect for hanging baskets or high shelves, where its long vines can cascade gracefully and add a touch of whimsy to any space.
Its better to grow this succulent in a pot or container where you can easily carry it indoors as soon as the temperature starts to drop for protection. by Succulents Box
Outdoors, String of Hearts can be a stunning addition to patios or gardens, especially in USDA hardiness zones 10 to 12. For outdoor growth, it’s important to place the plant where it can receive at least 3 to 4 hours of bright, indirect sunlight with some shade during the afternoon. This balance helps prevent the delicate leaves from burning in the harsh midday sun. Additionally, protect your plant from strong winds and sudden temperature changes to avoid damage to their trailing stems and foliage. In cooler climates, its best to grow String of Hearts indoors or bring outdoor plants inside during fall and winter, as they are not frost-tolerant and can be damaged if temperatures drop below 50°F.
