In the Central Valley, we have pretty extreme seasons. Summer days can be upwards of 110° and some winter nights as low as 28°. Asking plants from areas other than ours to be happy year round is not realistic. We have to choose plants carefully which can sometimes be overwhelming.
Succulents, which are mostly native to frost-free areas have become increasingly popular. Unfortunately, most horticulturally popular succulents are not able to withstand our freezing winter temperatures, making it hard to plan them into a landscape.
Here’s a list of succulents that have cold hardiness of 28°F or lower…but remember we have nights even colder than these as well!
In general, most Sempervivum sp. and Sedum sp. are frost hardy and Echeveria sp. tend to be sensitive to frost, but be sure to check the label as well!
