The cacciati that are winter hardy include opuntia (prickly pear), coryphantha, echinocereus, pediocactus and neobesseya.

What is the coldest temperature a cactus can survive?
Some cacti can cope with temperatures as low as 20 degrees below zero. These plants may have hairs that keep out frost, or they may expel water to keep the soil moist. Cactus and succulent plants can be grown in a wide range of temperatures, from the coldest to the warmest.
Some plants, such as succulents, can tolerate temperatures up to 120 degrees F (49 degrees C), while others, like cactus, will only grow at temperatures between 60 and 80 degrees. Cactus can grow in hot, dry climates as well as cool, wet ones, so it’s important to choose plants that will thrive in both.
What is the most cold hardy cactus?
The most cold-hardy include Great Plains natives like Escobaria, the wide-ranging Opuntia, and mountain dwellers, such as Echinocereus and Pediocactus, which can withstand temperatures as low as -50°F (-40°C). Cold-blooded animals can also be found in the Arctic, including polar bears, walruses, narwhals, beluga whales, seals and walrus calves.
Are Opuntia cold hardy?
Native as far north as North Carolina or possibly Virginia, Opuntia stricta is the tallest and largest of the cold-hardy prickly pears. The fruit is about 2 inches wide and 3 inches long. The deep red-purple flesh is quite tasty, a pleasing mix of sweet and sour.
Opuntias are native to the southeastern United States, but have been introduced to many other parts of North America. They are also found in Europe, Asia, Africa, and the Middle East.
Can aloe survive winter?
In U.S. Department of Agriculture plant hardiness zones 10 and 11, average minimum temperatures stay above 30 to 35 degrees Fahrenheit. It does not do well in temperatures under 40 degrees in the winter and tolerates lows from 50 to 60 degrees during the summer.
“It’s not a plant that you want to be in the middle of the night with,” said Dr. Michael J. Osterholm, an entomologist at the University of Minnesota, who has studied the plant for more than 20 years.
Do cactuses like the cold?
Cold hardy cacti benefit from a bit of shelter, but they may be surprised by their resilience in the face of extreme cold. Cold hardiness is determined by the temperature of the soil in which the cactus is grown. Cactus that are grown in hot, dry, sandy soil are more likely to survive cold temperatures than those that grow in cooler, wetter soil.
This is because the plant’s roots are able to absorb water from the surrounding soil and use it to keep their roots warm. In cold climates, however, the roots can’t do this. Instead, they have to rely on the sun’s heat to warm them up and keep them from freezing to death.
What happens if a cactus gets too cold?
Typically, cacti plants exposed to extremely cold temperatures will start to rot. Plants that were exposed for a long period of time will be destroyed by frost damage. If you can see frost on the plant, it is most likely damaged. If it doesn’t look like it has been damaged, then it isn’t damaged and you don’t need to worry about it.
Can I put my indoor cactus outside?
You can move indoor cactus plants outdoors during the summer when nighttime temperatures are at least 65 degrees F. Start their outside stay in a protected spot and allow them to get used to being outside, then move them to an area with more sun. If you want to move plants between indoors and outdoors, the morning sun is the best time to do it.
If your plants look healthy and are growing well, they’re ready for indoor or outdoor placement. If you notice any signs of disease or insect infestation, you’ll want to check with your local nursery to see if they’ll be able to help you move your plant indoors.
