Did You Know?
1. Despite their reputation as heat-loving plants, succulents can actually withstand extremely cold temperatures. Some varieties, such as the hardy Sedum rupestre, can tolerate temperatures as low as -20 degrees Fahrenheit (-29 degrees Celsius)!
2. The ability of succulents to survive freezing temperatures lies in their unique adaptations. They often have fleshy leaves that store water, which expands when frozen and can cause cell damage. To prevent this, succulents produce specific compounds that act as antifreezes, allowing them to endure cold conditions.
3. One interesting adaptation of cold-tolerant succulents is their capability to undergo partially controlled freezing. Some species, like the ice plant (Delosperma sp.), can freeze parts of their tissues without harm, selectively protecting vital areas while sacrificing less important ones. This remarkable ability helps them survive in regions with frosty climates.
4. Succulents exhibit a phenomenon known as “frost hardening” in response to approaching cold weather. When exposed to cool temperatures in autumn, succulent plants gradually increase their sugar content, acting as natural antifreeze agents. This mechanism prevents ice crystal formation within their cells, preserving their tissues even as the mercury drops.
5. Native to the Andes Mountains, the Puya raimondii is a giant flowering succulent that thrives in freezing conditions above 10,000 feet (3,000 meters) in altitude. Nicknamed the “Queen of the Andes,” this remarkable plant can endure temperatures as low as 5 degrees Fahrenheit (-15 degrees Celsius) for short periods, thanks to its thick insulating coat of woolly hairs.
Types Of Succulents: Hardy Vs Soft
Succulents, those striking and resilient plants that have gained popularity worldwide, can be categorized into two main types: hardy and soft succulents.
Understanding the key distinctions between these two types is essential in providing the optimal care for these remarkable plants.
Hardy succulents, as the name suggests, are able to withstand below-freezing temperatures with relative ease. Their natural adaptations allow them to endure harsh weather conditions that would be detrimental to other plants. These succulents possess thick and fleshy leaves, stems, or both, enabling them to store water in their tissue. Examples of hardy succulents include varieties of Sempervivum, Sedum, and Agave.
On the other hand, soft succulents are more sensitive to freezing temperatures and require extra protection. Their leaves are usually thinner and less waxy, which makes them more susceptible to frost damage. Soft succulents, like Echeveria and Kalanchoe, prefer milder climates and are often sought after for their beautiful rosette formations and vibrant hues.
Cold Tolerance: Hardy Succulents Vs Soft Succulents
When it comes to cold tolerance, hardy succulents stand out as the champions. These resilient plants have remarkable adaptations that allow them to thrive even in freezing conditions. They can withstand temperatures as low as -20 degrees Fahrenheit (or -29 degrees Celsius) without suffering severe damage. However, it’s important to note that prolonged exposure to extreme cold can still have adverse effects.
Soft succulents, on the other hand, are much more delicate when it comes to cold temperatures. While some soft succulents can tolerate temperatures just above freezing, they are generally more susceptible to frost damage. Freezing temperatures can cause their cell walls to rupture, leading to irreversible damage or even death. To ensure the survival of soft succulents, it is crucial to protect them from freezing temperatures.
Preferred Temperature Range For Soft Succulents
Soft succulents thrive in temperatures above freezing. Ideally, they prefer temperatures above 32 degrees Fahrenheit (or 0 degrees Celsius) to maintain their health and vitality. To flourish and display their stunning characteristics, soft succulents should be kept within the optimal temperature range of 50 to 85 degrees Fahrenheit (or 10 to 29 degrees Celsius).
During colder months, soft succulents may enter a dormancy period. This allows them to conserve energy and protect themselves from cold-induced damage. While in dormancy, these succulents often undergo amazing color changes, further enhancing their mesmerizing beauty. Notably, Anacampseros Pink Sunrise and Graptoveria Debbie are two soft succulents that display striking color transformations during fall and winter.
- Soft succulents thrive in temperatures above freezing.
- Ideal temperature range: 50 to 85 degrees Fahrenheit (or 10 to 29 degrees Celsius).
- During dormancy, soft succulents undergo remarkable color changes.
- Anacampseros Pink Sunrise and Graptoveria Debbie display stunning color transformations during fall and winter seasons.

Frost Hardy Succulents And Extreme Cold Tolerance
Frost hardy succulents possess exceptional cold tolerance, making them unsung heroes in the plant kingdom. These robust plants can endure extreme cold temperatures without significant harm. Their ability to adapt to freezing conditions is owed to their unique traits, such as well-insulated leaves and stems, deep root systems, and specialized physiological processes.
Some frost hardy succulents, including certain species of Sempervivum and Sedum, are able to handle extreme cold. However, it’s important to note that not all Sedum species are cold hardy, so it’s essential to research specific varieties before exposing them to freezing temperatures.

Protecting Succulents In Cold Weather: Indoor Or Outdoor Care?
To safeguard succulents from freezing temperatures, certain precautions must be taken:
- Hardy succulents can handle colder temperatures, but it is advisable to provide them with some protection.
- Soft succulents should never be exposed to freezing temperatures, as it can lead to their demise.
When the weather dips below freezing, you can take the following steps to protect your succulents:
- Bring succulents indoors or cover them with frost cloth. This creates a protective layer that shields the plants from direct contact with cold air and helps maintain a more stable temperature.
It is crucial to ensure that succulents are planted in well-draining soil, especially for cold-hardy varieties. Well-draining soil prevents root rot by allowing excess water to flow away. This is especially important during cold weather when excessive moisture can harm the succulent’s root system.
Before exposing any succulent to outdoor conditions, determine its hardiness zone. The hardiness zone indicates the specific climate conditions the plant can tolerate. By identifying the appropriate hardiness zone for a succulent, you can make informed decisions regarding its outdoor care and protect it from potentially damaging weather conditions.
understanding how cold succulents can tolerate is crucial in providing the best care for these remarkable plants.
