Hibiscus is a tropical plant that can tolerate cold weather. The coldest a hibiscus can tolerate is 50 degrees Fahrenheit. Hibiscus can survive in colder climates if they are protected from the wind and frost.
When the temperature drops below 50 degrees, the leaves of the hibiscus will start to turn brown and wilt. If the temperature continues to drop, the leaves will eventually fall off and the plant will die.
When most people think of hibiscus, they envision a tropical plant that can’t tolerate cold temperatures. However, there are actually several varieties of hibiscus that can survive in colder climates. The hardiest of these is the Rose of Sharon (Hibiscus syriacus), which can tolerate temperatures as low as -15 degrees Fahrenheit.
If you’re looking for a Hibiscus to add to your garden that can withstand some cold weather, the Rose of Sharon is a good option to consider.
What is the Coldest a Hibiscus Can Tolerate
Hibiscus are tropical plants that thrive in warm climates. They can tolerate brief periods of cooler temperatures, but prolonged exposure to cold weather can damage or kill the plant. The minimum temperature a hibiscus can tolerate is around 50 degrees Fahrenheit.
In colder climates, it is best to grow hibiscus as houseplants or in greenhouses where they will be protected from the cold.

How to Tell If Hibiscus is Hardy Or Tropical
If you want to grow hibiscus, you need to know if it is a Hardy Hibiscus or Tropical Hibiscus. Here are some tips on how to tell the difference:

Hardy Hibiscus can tolerate colder temperatures and does not need as much heat and humidity as Tropical Hibiscus. 3. The flowers of Hardy Hibiscus are typically pink, red, or white, while those of Tropical Hibiscus are often more brightly colored.
4. Hardy Hibiscus is generally easier to care for than Tropical Hibiscus.
Assuming you’re referring to the blog post titled “What the Coldest a Hibiscus Can Tolerate” found at https://www.gardeningknowhow.com/plant-problems/environmental/what-is-the-coldest-temperature-a-hibiscus-can-tolerate.htm, here is a summary:
Hibiscus plants are tropical flowers that can tolerate colder temperatures than most other tropical plants. However, there is a limit to how cold they can tolerate.
The coldest temperature a hibiscus can tolerate is around 32 degrees Fahrenheit. Anything below that and the plant will start to experience damage. This damage can range from leaves turning brown and falling off, to the plant dying entirely.
If you live in an area where temperatures dip below 32 degrees Fahrenheit on a regular basis, it’s best to grow your hibiscus plants indoors or in a greenhouse where they will be protected from the cold weather.
