Did You Know?
1. Succulents can tolerate temperatures as low as 20°F (-6°C), but prolonged exposure to freezing temperatures can damage or kill them.
2. Some species of succulents, like Sedum acre, can survive in subzero temperatures, with records of them enduring temperatures as low as -40°F (-40°C) in extreme conditions.
3. Certain types of succulents, such as Sempervivum, undergo a biological process called vernalization, where exposure to cold temperatures for a specific duration triggers the plants to produce flowers in the following growing season.
4. Succulents from desert regions have developed unique adaptations to cope with extreme temperatures, such as storing water in their leaves or stems, reducing the surface area of their foliage to minimize water loss, and developing a waxy coating or hairy texture to reflect sunlight.
5. When subjected to cold temperatures, some succulents exhibit a natural response called “frost hardening,” where their cells produce proteins that act as antifreeze, preventing ice crystals from forming and protecting the plants from damage.
Types Of Succulents: Hardy Vs. Soft Succulents
When it comes to succulents, there are two main categories: hardy succulents and soft succulents.
- Hardy succulents are resilient and can withstand below-freezing temperatures, even as low as -20 degrees Fahrenheit (-28 degrees Celsius). Certain Sempervivum and Sedum species fall into this category.
- They have adapted to survive in harsh environments and developed specific mechanisms such as water storage in their leaves and a thick waxy outer layer that helps insulate them from the cold.
On the other hand, soft succulents like Echeveria and Crassula varieties are more delicate and vulnerable to freezing temperatures. They can typically withstand temperatures above 32 degrees Fahrenheit (0 degrees Celsius), preferably around 40 degrees Fahrenheit (4 degrees Celsius) and higher.
Anything below freezing can be detrimental to their survival and may even result in the death of the plant.
Frost Tolerance: Hardy And Soft Succulents
Frost hardy succulents are exceptional plants that can withstand extreme cold, withstanding temperatures as low as -20 degrees Fahrenheit (-28 degrees Celsius) without significant damage[^1^]. However, it’s important to note that not all succulents have this ability, so it’s important to understand the specific requirements of each plant.
Soft succulents, on the other hand, are very vulnerable to frost damage. When exposed to freezing temperatures, the cells within their leaves can freeze, leading to the collapse of the plant’s structure. If soft succulents are left in freezing temperatures for an extended period, they will eventually die. To ensure the survival of soft succulents during cold snaps, it is crucial to provide them with adequate protection[^2^].
- Frost hardy succulents can withstand temperatures as low as -20 degrees Fahrenheit (-28 degrees Celsius).
- Soft succulents are highly susceptible to frost damage.
- Provide adequate protection for soft succulents during cold snaps.

Effects Of Cold Temperatures On Soft Succulents
When exposed to cold temperatures, soft succulents can experience several effects. One notable consequence is dormancy. Cold temperatures act as a trigger, causing succulents to enter a dormant state. During this period, succulents may slow down their growth, reduce water intake, and conserve energy until warmer conditions resurface.
Another effect of cold temperatures on soft succulents is a change in color. As the temperatures drop, succulents may undergo a vibrant transformation. Green succulents may develop hues of pink or red, while purple succulents may deepen in color. This change in pigmentation is a fascinating natural phenomenon that does not harm the plants.
To ensure the health of soft succulents during colder months, it is essential to provide them with suitable conditions. Ideally, temperatures should remain within the range of 40-60 degrees Fahrenheit (4-16 degrees Celsius). Additionally, maintaining dry soil during this period can have a beautiful effect on succulents. This combination of conditions allows the plants to thrive and adds an aesthetic appeal to their foliage.
- Soft succulents can go dormant in response to cold temperatures.
- Cold temperatures can cause a change in color in soft succulents.
- The recommended temperature range for soft succulents during colder months is 40-60 degrees Fahrenheit (4-16 degrees Celsius).
- Dry soil maintenance during this period can enhance the appearance of soft succulents.

Color Changes In Succulents During Cold Months
Cold temperatures can cause succulents to undergo striking color changes. This fascinating phenomenon adds visual interest to any succulent collection.
For instance, the Anacampseros Pink Sunrise succulent displays a dramatic color change in the fall and winter months when temperatures consistently range from 45 to 60 degrees Fahrenheit (7 to 16 degrees Celsius). During this time, the pink color of the succulent becomes more vibrant, creating a stunning visual display.
Similarly, the Graptoveria Debbie succulent transforms from a pale pastel purple to a deep purple color, delighting succulent enthusiasts with its evolving beauty.
It is worth noting that these color changes are a natural response to cold temperatures and should not be a cause for concern. They add an element of intrigue and uniqueness to each succulent, making them even more captivating.
Protecting Succulents From Freezing Temperatures
To protect your succulents from freezing temperatures, there are certain measures you can take. These precautions will ensure the continued health and survival of your beloved plants.
If the weather forecast predicts temperatures below freezing at any point during the week, it is highly recommended to bring your succulents indoors or cover them with frost cloth overnight. This extra layer of protection helps insulate the plants, preventing them from succumbing to freezing temperatures. Additionally, placing succulents in a warm area indoors safeguards them from the potential dangers of frosty conditions.
Moreover, it is crucial to consider a succulent’s hardiness zone before placing it outdoors in a specific environment. Each succulent species has its own tolerance level for cold temperatures. By understanding the hardiness zone of your succulents, you can make informed decisions about where to plant them and what precautions to take during winter months.
Hardy succulents can withstand freezing temperatures, while soft succulents are more vulnerable to the cold. It is important to provide adequate protection for soft succulents during cold snaps, either by bringing them indoors or covering them with frost cloth.
