Orostachys chanetii is a succulent plant that forms small rosettes of grayish-green leaves with red tones. The rosettes grow up to 2 inches…
The common cold-hardy succulents shown here can handle northern winters, snow, rainstorms (if given excellent drainage) and summer dry spells.
Most cold-hardy succulents are in the genera Sedum and Sempervivum.
Trailing varieties are lovely as ground covers and in rock gardens, terraces and hanging baskets. Larger-leaved Mexican sedums (such as burro tail) are less tolerant of damp cold and need to be overwintered indoors or kept in greenhouses. Shrub sedums die back in winter and return in spring. All produce clusters of star-shaped blooms.

Sempervivum (hen and chicks)
These resemble echeverias but rosettes have thinner, pointed leaves and a more compact, spherical form. A similar genus, sometimes lumped with Sempervivum, is Jovibarba. These and Rosularia resemble sempervivums and have similar cultivation requirements. Learn more about "semps" and see photos of dozens of beautiful varieties at Mountain Crest Gardens.
Certain species of Agave, cacti and ice plants also can handle all but the coldest climates.
Agaves that are cold-hardy (if kept dry) include A. ‘Baccarat’, which can go to zero degrees F. For more on agaves, yuccas and cacti for northerly climates, see the Cold-Climate Succulent Gardens section of Designing with Succulents (2nd ed.).
These ice plants have satiny, daisylike flowers in brilliant hues of pink, orange, red, yellow, purple and combinations thereof. They make great rock garden plants.
Little known but well worth having are cold-hardy lewisias and orostachys.
Native to the Pacific Northwest, this genus is named after explorer Meriwether Lewis of the Lewis & Clark Expedition. Lewisia has been extensively hybridized, resulting in vivid-hued cultivars.
This intriguing annual makes a great pot plant. When bred with Sedum the intergeneric cross is Sedoro.
