Can Wildflowers Survive Frost?

Winter is a tough time for any plant, but there are some that can survive even the coldest winters. Wildflowers are hearty survivors that can thrive through even the harshest winters. They’re also beautiful additions to your yard and garden, so if you want more colors than just green grass in the wintertime, this post will show you how to keep them around for years!

Can Wildflowers Survive Frost?

You can grow wildflowers in your garden to attract wildlife and add color to your landscaping. Many types of wildflowers are hardy and will thrive in many different regions, but some need specific temperatures to survive. The most common way for frost to kill a plant is by destroying the tissue at its base that holds the stems up out of the ground. If this happens, even if the upper part of the plant survives, it won’t be able to produce flowers or seeds.

In general, any native wildflower that grows in full sun (at least 6 hours per day) should be able to survive a light frost with no problem. These plants usually have roots that go deep into the soil where they’re protected from freezing temperatures overnight by high temperatures during sunny days and warm soil during sunny nights.

However, some wildflowers prefer shady areas because they don’t get enough light when fully grown or need protection from strong winds like those found on open hillsides or cliffsides; these flowers may not survive frost very well at all!

How Does Frost Affect Wildflowers?

Frost can damage wildflowers in several ways.

  • Flower buds are killed, leaving the plant to produce flowers later in the year.
  • The roots can be damaged, which will slow down growth and flowering.
  • Stems can break off and die if there is severe frost or if temperatures fall very quickly (a process known as “frost heaving”). This is especially common with perennials like peonies, delphiniums, and lilies — plants that grow from bulbs rather than seeds.
  • Leaves may turn brown or black at the tips but usually recover by springtime if they weren’t badly damaged by frost.

How Tolerant Are Wildflowers To Cold Weather

When it comes to the question of frost tolerance, there is no such thing as a one-size-fits-all answer. Instead, wildflowers’ responses to cold weather are determined by several factors, including their:

  • Size and growth stage. Smaller plants that haven’t started blooming yet tend to be more tolerant of freezing temperatures than fully mature ones that have already begun flowering. Similarly, newly planted seeds may be able to withstand colder temperatures than plants that have been around for years or decades.
  • Exposure level (how close they are to open ground). Plants closer to the surface are more likely to experience damage from frost since they’re less protected by snowfall and other insulating barriers like mulch or leaves on top of the soil layer where they grow.

How To Protect Your Wildflowers From Frost

The key to protecting your wildflowers from frost is to make sure they are planted in a spot that isn’t affected by the cold. You can plant them in the yard, but if you live in an area that gets a lot of frosts, then it’s best to plant them in a container or bury them in the ground.

If you choose to plant your flowers in a container, make sure that you choose one that has good drainage. This will ensure that water doesn’t pool up and cause root rot. It’s also a good idea to add some peat moss or other organic material on top of your soil so that water won’t stay around long enough for any roots to become wet.

If you choose to bury your flowers in the ground, make sure that the soil is loosened up well before planting so that roots can easily grow into it without any issues. You may also want to consider adding some mulch around where you’re planting so that moisture doesn’t collect there too quickly or easily drain away from where they’re growing.

Caring For Wildflowers During The Winter

As the winter months begin to take hold, wildflowers aren’t affected by frost. They’re not cold-blooded and don’t need to be warmed up before photosynthesis can occur. Frost does not kill the plants; it simply damages their leaves and stems. The best way to protect your flowers from frost damage is by covering them with sheets or blankets until temperatures rise above freezing again.

Watering wildflowers in the winter are essential for their survival; however, you should water them only if there has been no precipitation in several days and you have sandy soil or clay soil (sandy soil drains better than clay).

If you’re unsure whether your soil drains well enough for watering, dig down about 6 inches (15 cm) with a shovel first, then fill the hole with water gauge gel and wait 15 minutes to see how much seepage occurs before making any decisions about watering needs.

What Temperatures Will Kill Wildflowers?

Although native wildflowers are tough and resilient, they can still be killed by cold temperatures. The temperature at which a wildflower will die can vary depending on the species.

But generally, most wildflowers will survive temperatures between 10 and 15 degrees Fahrenheit (about -9 to -9 degrees Celsius). Below that range—down to 5 degrees Fahrenheit—most of your favorite wildflowers will die.

Can I overwinter Wildflowers?

Yes, you can overwinter wildflowers. To overwinter wildflowers, you’ll need to dig them up and store them in a cool location with no light.

Once they’ve been stored for a few weeks to several months, remove the top layer of soil and plant them again as soon as possible. If you don’t do this right away (or if your plants aren’t growing well), then wait until spring when temperatures are warmer before planting again.


We hope that this article has helped you understand how to protect the wildflowers in your garden. Most varieties of wildflowers are able to withstand frost, but if the frost is for an extended period of time, it can kill them. As long as you keep your wildflowers protected, they should survive the frost without any issues.
