Based on the varieties of succulents, the answer to that question will be altered. We can divide all succulents in the world into two groups, as hardy and soft. Some types of succulents can be handled below freezing temperatures. Some few species can live outside when it is -30 degrees.
Soft succulents can be called as tender succulents, and Aloe, Echeveria, Crassula Jade, Kalanchoe, Senecio and Tender Sedums are the examples for soft succulents. Soft succulents can grow indoors and adapt to warm environments like deserts. These kinds of plants don’t have any adaptations to deal with cold temperatures.
Because of those soft succulents it is difficult to handle below-freezing temperatures. Finally, soft succulents can be damaged and finally, death can happen due to cold temperature.
Hardy succulents are hard, compact plants that can handle a great deal. Sedum and Stonecrops are the hardy succulents in the world. Hardy succulents can be tolerated below freezing temperatures because they grow in mountainous environments in northern climates.
They are not recommended to indoor use and year-round in most of the United States. On the other hand, this type of succulents can be handled all the climatic seasons.

What happens when succulents get too cold?
Effects are changed according to the species and hardiness of the succulents.
Some types of succulents will not change much with too cold climatic conditions but other some species will change their color with a really nice way, and others will go dormant. If they do not carry to the interior or prevent from too cold weather, the remainder will freeze and die.
Can succulents survive a freeze?

Can they become Dormant in the cold?
Succulents do not grow in the same rate year-round. Some go through a dormant process and an active phase. Succulents go dormant when climatic conditions badly affect their growth and maintain the life cycle.
But the temperature at which succulents go dormancy depends on species. Some cold-hardy some succulents can tolerate frost but go dormant below freezing temperatures. Sempervivums are examples for the above incident. But Echeverias are gone dormant at a higher temperature.
During the winter, some succulent species go to the dormant period, while those in the summer enter dormancy. Examples for dormant winter succulents are Adenium, Agave, Ceropegia, Echeveria, Opuntia, Tillandsia, Pachypodium and summer dormant succulents are Aloe, Aeonium, Crassula, Lithops, Senecio, Sedeveria and Crassula.
What succulent species can handle the extreme cold?
All Sempervivum (called as hens and chicks) and some Sedum species can be handled extreme cold. Otherwise, Rosularia, Delosperma and Orostachys also can be tolerated for extreme cold. These two types of succulent species can be endured to -20 degrees of Fahrenheit.
What is the optimal temperature for Succulent?
The response to this question would depend on the forms and types of succulents. Hardy succulent types can be cold hardy or frost hardy. But some cannot tolerate the frost at all. Others will grow better in full sun and tolerate too heat conditions and rest will need to protect from the too heat conditions.
Generally, most succulents can be kept in temperatures between 45-85 degrees Fahrenheit (7-29 degrees Celsius). Soft succulents will tolerate over 0℃, but preferably 4℃ and they need to be protected from freezing temperatures and frost. Hardy succulents can be frost hardy or cold hardy.
Both cold-hardy succulents and frost hardy succulents will be tolerated outdoors in the winter. Frost hardy succulents will tolerate -6℃. They can tolerate temperatures below freezing.
How cold can cactus tolerate?
Cactus has several adaptations to survive in cold environments, and they have to do with managing water. Cactus goes dormant when temperatures below freezing.
Then cactus stops growing and limit their cellular process. On the other hand, due to low water inside the plant, there is less risk to crystallization due to freezing, and this allows us to act as a natural antifreeze that offers some protection.
Do succulents need to come inside during winter?
The answer to that question will depend on the type of succulent.
Hardy succulents – This type of Succulent can be tolerated during winter and can stay outdoors through below-freezing conditions. Thus, year-round outdoor growing can be accepted for hardy succulents, and they grow and stay better outdoors than inside.

Blue succulents are Blue Chalksticks (Senecio serpens), Blue Glow (Agave attenuata × Agave ocahui) and Blue Spurce (Sedum reflexum). Red succulents are campfire Plant (Crassula capitella), Desert cabbage (Kalanchoe luciae), Lipstick (Echeveria agavoides) and Stick on fire (Euphorbia tirucalli)
Light, water and temperature are the key elements that create cold stress colors. Specific succulents are produced really nice colors or unique pigments after exposed to unusual light, temperature or water as a respond.
