Hardy and drought-tolerant perennial plants known as stonecrop (Sedum spp.) are well-liked in xeriscaping, rock gardens, and containers. From the ubiquitous, two-foot-tall, long-blooming Autum Joy to the adorable groundcover stonecrops like ‘Dazzleberry,’ stonecrop comes in a range of shapes and sizes.
Sedum can it endure winter?
Succulent plants called sedums thrive in climate zones 3 to 9. Sedum is one of the toughest succulents available due to the fact that succulents are notorious for storing water in their leaves. Sedums can withstand hot weather, dry soil, and cold temperatures. Sedum won’t need a lot of winter maintenance, unlike most perennials.
Sedums can be neglected when you tidy up and cut your garden space for the winter. Sedums are hardy plants that can withstand cold and temperatures below zero. Sedums that are standing upright will eventually fade back to the ground, but the surviving stalks with spent flowers will still provide color and food for the birds. Pruning the stalks all the way to the ground is an option. The plant and the spring’s fresh growth won’t be harmed.
Does sedum require protection from frost?
My new succulents, which I planted in containers over the course of last summer, have practically turned to mush as a result of the most recent cold spell, Howard writes.
The succulents’ growing zones in my garden saw temperatures as low as 27 degrees Fahrenheit.
Do any succulents have the ability to withstand colder temperatures? What can I do going forward to prevent freezing damage to the plants? Additionally, do you have any helpful suggestions for extra growing techniques? I’m not prepared to give up on the “succulent challenge” just yet.
I spoke with Charolett Baron, an expert succulent and cactus aficionado, and I inquired about how her collection of succulents had fared through our abnormally cold conditions.
She also revealed some of the hard lessons she had to learn about cultivating succulents after she too lost some of her favorite specimens in a prior cycle of extremely cold temps.
Here are some of her tips for choosing succulents that can withstand freezing weather as well as what she does to safeguard her collection of succulents and cacti:
She has discovered that the agave, “After Glow,” is more tolerant of freezing temperatures and that the yucca, “Wall Bright Star,” is resilient to 0 degrees. These examples were discovered by Baron at Petaluma’s Cottage Gardens.
Specimens with variegation appear to be less robust. Frost is not tolerated by euphorbias. Despite the fact that they are supposedly hardy to, say, 30 degrees, container plants are more sensitive to lower temperatures.
Crassula sarcocaulis can withstand temperatures as low as 10. Hens and chicks, often known as sempervivums, can endure freezing temperatures. Stonecrops, commonly known as sedums, survive the freezing temperatures with little obvious damage.
Baron advises covering ALL of your succulent plants in breathable, frost-protective cloth that enables moisture and sunlight to pass through.
Although they must be removed during the day, thin sheets thrown over the plant in cold weather also works nicely.
Place the containers in sheltered spots like eaves. Wait until the weather warms up before going out on the water.
Run some low-voltage lights in your mini-greenhouse or bigger structure for added warmth, and keep the pots lightly covered in floating row covers—a frost-protective material—until no longer necessary.
Finally, her own succulent plants have survived because she covered them, including those in her greenhouse, in the ground, and in pots.
When the temperature dropped to 28 degrees, the sedums, sempervivums, Orostachys, Senecio mandraliscae, Crassula cocinea ‘Campfire,’ Rhodiela, and Aloe nobilis in my garden were unharmed.
Read the plant label before buying succulents because it will usually indicate whether or not the plant is cold-hardy. Some species within a given genus may be more resilient than others.
A protracted rainy period like the one we had will also reduce hardiness, as will the number of days with low temperatures.
The slightly more fragile succulent variety can be successfully grown by readers who live in a warmer area.
Surprisingly, visiting nearby neighbors who have had little to no plant frost damage will also assist you choose which succulents will do well in your own garden.
“Succulent Container Gardens, Design Eye-Catching Displays with 350 Easy-Care Plants” by Debra Lee Baldwin is a fantastic resource for all succulent fans.
This book provides answers to many queries regarding the cultural requirements of succulents, the hardiness of specific plants, and attractive container arrangements that use color, texture, and size that are appropriate for each container.
What distinguishes a yucca from an agave in terms of appearance, queries Cynthia?
Yuccas are mounding succulents that grow 2 to 3 feet tall and feature spiky foliage with stringy hairs along the margins. In the early or middle summer, they produce flowers on stalks.
Agaves grow in clumps and have leaves that are about 18 inches long, 3 inches wide, and have sharp, pointed points. Agaves, commonly referred to as century plants, don’t flower often, but when they do, it’s usually on stalks that extend several feet above the clump of foliage.
Is it acceptable to graft a citrus tree onto a camellia? asks Jess S. If it is not required, avoid removing the camellia’s root system.
What sedum is the hardiest?
Fine, small-leaved sedums are typically more heat- and cold-tolerant than those with big leaves. The 4-inch-tall tasteless stonecrop (Sedum sexangulare), which has yellow flowers and spiraling, green leaves that turn a copper color in winter, and the 6-inch-tall widow’s cross or sea star (Sedum pulchellum), which behaves like a winter annual, are examples of cold hardy sedum varieties that are advised in USDA zones 3 or 4 through 9.
Widow’s cross blooms throughout the summer with pink flowers before going to seed and dying, but the seeds it produces produce seedlings that appear in the late fall, develop through the winter, and bloom in the summer. The 4-inch-tall lance-leaf stonecrop (Sedum lanceolatum), which can withstand freezing temperatures, is hardy in USDA zones 4 through 9. It features yellow flowers and gray-green, needle-like leaves that can occasionally turn crimson in the winter.
How much ice can sedum tolerate?
When everything else in the garden is dormant, this low-growing groundcover spreads out in a dense mat of stems and leaves that turn crimson in the fall and remain scarlet all winter. Originally from the Caucasus region between Europe and Asia, Sedum spurium can withstand temperatures as low as 40 below zero. It produces tiny pink flowers in the form of stars that butterflies like. Allow it to trail over the sides when you plant it in a container or on a sunny slope. zone 3 to zone 8.
Sedum Care
Sedum plants, often known as stonecrop, do best in full sun, with little to no water, and, most critically, on soil that drains properly. For the flower bed and border, there are larger kinds that reach heights and widths of exceeding two feet. Old favorites for cottage gardens include “Fall Joy. Bright green, gray, and red ground cover kinds that spread swiftly and blossom in the early summer include “Angelina. everything in between as well! They are excellent container plants and do well in most gardens. Sedum plants feature succulent leaves that can be any color—gray, green, purple, blue, or even variegated—and can have anything from tiny needles to larger, fleshier leaves. Bees and butterflies adore them. The nicest part is that they are perennials and return year after year.
Here are a few expert recommendations for growing sedum plants that will look their best:
- Use a well-drained soil at all times. If you’re planting them in containers, make the soil mixture very permeable by adding some shredded bark or sand. Grow them in raised beds and containers if your garden soil is heavy, or amend it.
- Consider how the plants will feel while selecting your containers. To fit the modern vibe these plants exude, think concrete, stone, or simple round bowls if you want to create a succulent garden effect. However, don’t let that deter you from utilizing them in any type of garden—this is a fantastic way to modernize!
- Although they can go without water for extended periods of time, I find that if they are in well-drained soil, they look their best with moderate watering and a little bit of drying time in between.
- They don’t need rich soil or substantial fertilizers. Your plants will really become floppy with lots of stems but few leaves and blossoms if you overfertilize.
- Although the larger kinds will fall over if they don’t get enough sun, they can tolerate some afternoon shadow.
- Speaking of taller types, snip off the tops of the main stems in the spring when the plant is about six inches high. This will make the plant grow more tightly, which will solve the flipping over problem I stated earlier.
Try out various varieties of hen and chicks to plant with your sedums after you have the caring for them down. They are excellent sedum companion plants because they share the same needs for water and fertilizer. These are known as Sempervirens in Latin, so you can be sure you are purchasing the correct succulent. They look fantastic together in containers, as this image from “Sunset” demonstrates.
How do sedums appear in the winter?
Crevice gardens, wall gardens, and roof top gardens all benefit from the low water requirements and spreading habits of creeping sedums. Stonecrop is the preferred plant for roof gardens on commercial structures like the 32,000 square foot Toronto City Hall or the 10.4 acre Ford truck plant in Dearborn, Michigan. And there are literally millions of square feet of green roofs in Europe, most of which are covered in stonecrop vegetation. Most of these gardens lack irrigation, and the sedum depends entirely on rainfall to survive.
Autumn Sedum and Winter Sedum:
Cultivars of tall sedum like Autumn Joy are well known for their spectacular fall flower display. The autumn sedums are at their height as most of the garden begins to fade. Tall sedums dry out as fall turns into winter but remain lovely thanks to their frost-kissed stalks. The creeping sedums can also be stunning in winter because some of them, like Sedum tetractinum, have winter-colored leaves.
How does sedum survive the winter?
Since most sedums are quite hardy (check your plant tag to see the hardiness zone), if they are in a pot that can withstand the rigors of winter, you can leave them outside.
Remove the foliage and compost the leaves after it dies in the late fall or winter (discard any leaves that are diseased). For the winter, place the pot in a protected area. Ideal location is adjacent to a building in a shaded area. Some people think it’s a good idea to place the pots in the sun, but this is actually counterproductive because perennial plants’ roots can suffer greatly from unseasonable thaw/freeze cycles that can occur all winter in pots placed in the sun. Instead of repeatedly going through thaw/freeze cycles, which have the consequence of rupturing the root tissues, perennial plants are much better off being frozen for the whole winter. With many cases, pots that are covered in snow during the whole winter fare better than those that are left open to the elements.
In any case, be aware that plants overwintering in containers will endure extremely cold temperatures due to their constant exposure to chilly air. Make sure the plant is rated for two USDA zones cooler than the one where you reside if you plan to leave it in its pot. For instance, pick species rated for zone 4 if you live in zone 6. Additionally, you can shield them by wrapping the pots with burlap. Some gardeners even completely bury the pots in the ground to shield the roots from harsh temperatures for the winter before digging them out again in the spring.
Should I prune my sedum to prepare for the winter?
As soon as the blooms start to fade in the winter, you can trim the sedum back, or you can wait until the ground turns green in the spring. Use pruning shears to cut the entire plant back to the ground, or break the stalks by hand at the ground level. The sedum will reappear from the roots in the spring.
Which succulents can I keep outside over the winter?
Some succulents will thrive outside all year for you if you live in a climate with four seasons, particularly one with harsh winters, but most won’t.
Although most won’t endure prolonged frigid conditions, each succulent has varied temperature requirements.
But there is a whole class of gorgeous cold-tolerant plants that are largely ignored in the succulent world! Many individuals are unaware of their existence or how numerous they are.

Even if your environment dips well below freezing for the majority of the winter, you may still keep a lovely succulent garden outdoors using Sempervivums, select Sedums, and their hardy Opuntia relatives.
I started off growing succulents in Utah, which has a Zone 5 environment. I didn’t know there were succulents that could endure snow, therefore I was primarily cultivating succulents indoors.
Fortunately, Mountain Crest Gardens was recommended to me, and as a result, my succulent garden underwent significant improvement. According to my knowledge, Mountain Crest Gardens is the main source of cold-tolerant succulent species.
Their nursery is really located in a mountain valley near Mount Shasta in northern California, where they receive snow all winter. They have the most exquisite assortment of succulents that can withstand chilly temperatures.
These Sempervivums, Sedums, and Opuntias (also known as “Prickly Pear Cactus”) are wonderful since they can also survive in more temperate climes!
In the video below, you can learn more about what succulents can withstand below-freezing temperatures:
I have many sizable pots full of Sempervivums and Sedums that made the journey and are now flourishing here in Arizona, in addition to the numerous plants I did plant in the ground for my parents in Utah. I also want to expand my collection here with some cold-tolerant Opuntia.
Sempervivums are significantly harder than other rosettes succulents, such Echeverias, and make excellent rosettes if you are unfamiliar with how these succulents look. The color choices are also quite beautiful, ranging from pinks, reds, and purples to greens, yellows, and blues. You truly receive the entire rainbow!
The resilient Sedums are more of a ground cover and come in a wide range of forms, textures, and hues. You’ll find that some of them generate a wonderful trailing effect over the edge of your succulent pots, which looks fantastic when combined with Sempervivums.
My eye has been particularly drawn to the tough Opuntia. I was able to visit the Waterwise Botanical Gardens in Escondido, California, when they introduced a line of cold-hard Opuntias a few years ago. The most stunning flowers you’ll ever see on a succulent are produced by these plants in the spring, despite the fact that they may look like regular “Prickly Pear” cactus on the outside.
Opuntia “Pina Colada,” which has a blossom that truly changes colors, was one of my all-time favorites. It changes from being an orangey-pink color to yellow with pink and orange stripes in the middle the following day.
The amazing thing is that these cold-tolerant Opuntias are now available on Mountain Crest Gardens’ website thanks to a collaboration between Mountain Crest Gardens and Waterwise Botanicals.
So everyone who lives somewhere with four seasons, don’t forget to think about these incredible succulents! You’ll find that being able to observe some color and life in the midst of winter is very satisfying, in my opinion. Nothing compares to the Opuntias blooming at the start of spring, though!
It’s fascinating to observe how these hardy plants recover with vibrant, gorgeous hues even after spending the winter months buried beneath several feet or inches of snow. My awe for succulents never wanes!
