The string of hearts makes small, tube-shaped flowers that are usually purple or pink and smell very different.
With their cascading vines and distinctive heart-shaped leaves string of hearts have become a hugely popular houseplant. But there is often confusion around whether these striking trailing plants are actually succulents or not. In this article we’ll explore the succulent qualities of string of hearts and examine what makes their care and adaptations unique.
An Overview of String of Hearts Plants
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 earned the common name string of hearts due to their heart-shaped foliage that emerges along vining stems hanging down.
There are over 200 Ceropegia species, but C. woodii is the most common houseplant. It features delicate green leaves with silver variegation that resemble little dangling hearts. With proper care, the vines can grow several feet long, cascading beautifully over the sides of pots and baskets.
While native to subtropical Africa, string of hearts have become a popular indoor plant worldwide thanks to their trailing nature and relative ease of care compared to other houseplants. Their distinctive appearance also makes them a unique addition to any home.
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 say 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 out 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 9 feet long!
Differences in String of Hearts Compared to Other 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.
Common Problems Faced by String of Hearts
When their needs are not met, string of hearts succumb to issues like:
-
Leaf curling and wrinkling – Insufficient watering is a common cause. Slowly increase water.
-
Leaf yellowing or loss – Can indicate overwatering. Allow more time between waterings for soil to dry.
-
Elongated stems – Not enough sunlight causes leggy growth as the vines stretch for light.
-
Wilting – May signal underwatering or roots damaged by overwatering. Assess watering habits.
-
Failure to root from cuttings – Wet soil from overwatering rots freshly propagated plants. Use well-draining mix.
-
Pests – Mealybugs, mites, and aphids commonly plague string of hearts. Isolate and apply insecticidal soap.
Catching issues early and adjusting care is key to avoid decline. Familiarize yourself with signs of underwatering vs overwatering which commonly impact these subtropical succulents.
Caring for the Unique Nature of String of Hearts
While string of hearts do 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!
String of Hearts Light Requirements
Ceropegia woodii is a light-loving plant but does not like direct sunlight. For satisfactory growth, pay attention to the string of heart light requirements. To grow it indoors, put it near a window so the leaves can get light for four to six hours a day. You can use artificial grow lights to give your String of Hearts the light it needs if you don’t have a window with bright, indirect light. Just make sure to keep the lights a few feet away from the plant to prevent heat damage.
String of hearts plants should be kept out of direct sunlight if they are grown outside. Some shade can help with this. Keep an eye on your heart plant to ensure its getting the right amount of light. When the leaves turn pale or stretch toward the light, it may mean that the plant needs more light. What if, though, the leaves start to turn yellow or brown? That could mean there is too much sunlight.
By giving your String of Hearts the right amount of bright, indirect light, you can help it grow and keep its lovely look.
