Hardiness varies considerably among the different types. Most tender succulents with rosettes of thick fleshy leaves, such as many of the Echeverias, are partially hardy to at least 25 °F (-3.9 °C. Tender succulents with thinner individual leaves, like most Kalanchoes, can briefly tolerate temperatures just below freezing point but are killed back to the roots when the temperature reaches 25 °F (-3.9 °C.
This modest hardiness means they do well outdoors in regions that receive only light frost (such as many coastal locations) and in protected spots in colder regions.
