Can Pansies Survive A Freeze?

When it comes to flower gardening, many gardeners ask if their pansy plants can survive frost and freezing temperatures. The short answer is yes. Depending on the severity of the freeze, pansies and violas are capable of surviving temperatures as low as 20 degrees Fahrenheit (-7 degrees Celsius) for short periods of time. In this article, we’ll take an in-depth look at what happens to pansy plants during a freeze, how long they can survive, and how to protect them from frost and freezing temperatures.

The Different Varieties of Pansies

Pansy plants come in both single-flowered and double-flowered varieties. The single-flowered variety produces larger blooms, while the double-flowered variety produces smaller flowers with more petals. Both are hardy plants that can survive in most climates, though they prefer cooler weather. They can be grown indoors for winter color or planted outdoors for spring and summer blooms.

What is a Freeze?

A freeze occurs when temperatures drop below 32 degrees Fahrenheit (0 degrees Celsius). Although some areas may experience light frosts or hard freezes, the effects on pansy plants will depend on the severity of the freeze. A light frost may cause some wilting or damage to flowers that were in bloom, but the plant itself will usually remain alive. A hard freeze will cause more significant damage to both flowers and foliage, but the plant can still survive if temperatures don’t stay too low for too long.

How Cold Does a Freeze Get?

A hard freeze occurs when temperatures drop below 20 degrees Fahrenheit (-7 degrees Celsius). This type of cold weather isn’t common in most regions but can occur during winter months in some areas. When this happens, pansy plants can become damaged or even killed if left unprotected for too long.

Why Would Pansies Survive a Hard Freeze?

Pansy plants are resilient and are able to survive cold temperatures due to their thick foliage which helps insulate them from the cold air. They also have deep root systems which allows them to access water even when soil conditions are unfavorable. This combination allows them to withstand colder temperatures than other plants would be able to handle without succumbing to frostbite or death.

What Happens to Pansies During a Freeze?

When exposed to freezing temperatures, pansy plants may suffer from wilting or damage to their flowers and foliage due to frostbite. If exposed long enough, they may even die due to extreme cold stress or dehydration caused by frozen soil conditions.

How Long Can Pansies Survive a Freeze?

Pansy plants are able to survive freezing temperatures for short periods of time before becoming damaged or dying due to dehydration or cold stress. Depending on the severity of the freeze, they may be able to withstand it for several days before succumbing if not properly protected from the elements.

How To Protect Your Pansies From Freezing Temperatures

If you live in an area prone to freezing weather during winter months, there are several steps you can take to protect your pansy plants from frost damage and death. Covering them with lightweight blankets or sheets is one option that will help keep your plants warm while still allowing air circulation beneath them, plastic covers should be avoided as these can trap moisture which could lead to mold growth or rot on your plants’ roots.

You can also add mulch around your pansy plants which will act as an extra layer of insulation against cold temperatures, just make sure not to pack it down too tightly so that it doesn’t restrict air circulation around your plants’ roots.

Common Problems Associated With Freezing Temperatures And Pansies

One common issue associated with freezing weather is fungal diseases such as powdery mildew which thrive in cooler climates, this type of disease will cause spots on leaves and stems which eventually leads to wilting if left untreated. Another potential problem includes root rot caused by overly wet soil conditions, this type of rot will cause your pansy’s roots become soft and mushy leading eventually leading death if not treated promptly with fungicides.


Pansys are hardy plants that can survive frost and even hard freezes for short periods of time depending on how severe the temperature drops get. While they may suffer some minor damage during these times, they should remain mostly unharmed if protected properly. By following simple steps such as covering with lightweight blankets , adding mulch , avoiding plastic covers, and treating fungus promptly, you should be able keep your pansys healthy despite potentially harsh winter weather conditions.
