13 U.S.-Native Plants That Can Withstand Extreme Cold
Winter frost threatens tender gardens! Plant native species that withstand extreme temperatures and you’ll never have to worry again. Native plant gardener Jerad Bryant shares 13 U.S.-native plants perfect for chilly landscapes.

Contents
Many North American gardens receive significant frost from November through March. It settles in on tender plants, sucking moisture from their stems and freezing it. Unless a plant has natural defenses, it’ll succumb to the extreme weather conditions and die before spring returns.
When plants evolve in cold regions, they grow accustomed to recurring frosts and develop a strong tolerance for frost. Many take on a perennial nature, entering dormancy during winter and sprouting anew when warm weather arrives. Others have thick, frost-tolerant foliage, or they’re deciduous and lose their leaves.
No matter how they survive the winter, native plants are excellent options for North American gardens. They require less water, nutrients, and care than non-native species, and they offer prized nectar and pollen to pollinating insects in spring.
These species are incredibly tolerant of severe cold, making them ideal for chilly gardens throughout the U.S. Choose from these 13 groundcovers, perennials, and deciduous shrubs to design the climate-hardy garden of your dreams.
Purple Coneflower Echinacea Seeds

Echinacea grows well in a variety of conditions, and is excellent for borders and water-wise gardens. Perfect for fresh cut flowers.

Kinnikinnik, or bearberry, is a frost-loving groundcover that creeps along the soil. Its woody stems root freely along the ground, creating large colonies of evergreen growth. Resisting extreme frost, this native groundcover retains its leaves despite freezing temperatures. It’ll survive winters in USDA Hardiness Zone 2 with extra mulch protection.
Kinnikinnik is a close relative of Manzanita trees and shrubs. Its leaves, flowers, and peeling bark resemble them, though they’re much smaller on the groundcover. It’ll grow despite frost, snow, and ice. Plant it as a low-growing groundcover for the best results. Alternatively, try situating it on rock walls so it drapes and hangs.

The iconic perennial fireweed is essential for wild landscapes! It reseeds readily, and it sprouts from underground roots in spring. Long flowering stems sprout in spring with rows of pink-red blossoms. After wildfires, fireweed is one of the first native plants to return to the burned area. This is why it has the word “fire” in its name.
Because of its weedy tendencies, this plant is best for wild and natural landscapes without formal lines and borders. Seedlings will sprout far from the mother plant, as the seeds have tufts on them that help them float large distances. Pull seedlings up if you don’t want them—throw them in your compost for free soil!
Ostrich Fern

Shady gardens are often difficult to plant in, as sun-loving plants struggle to photosynthesize under low light. That’s why shade-loving plants are essential for these spaces! Ferns are ideal options, as they perform well in dense shade. The ostrich fern is a superb type for North American landscapes.
Not only is this native fern plant incredibly cold-hardy, but it also produces edible fiddleheads! They emerge after the snow melts in spring, producing lovely tender greens that sauté well in many recipes. Not all fern fiddleheads are edible, so be sure to verify the plant you collect is the one you intend to eat.

Purple coneflowers are iconic wildflowers from the Great Plains ecoregion. They’re herbaceous perennials that enter dormancy in winter. They stay safe underground in their roots before emerging with new growth in spring. Dozens of varieties exist with various colors, offering unique hues for your garden designs.
In order to withstand the cold, these native plants must grow for some time before fall frost arrives. Sow seeds at least two months before the first average frost date, and they’ll overwinter well. For spring plantings, sow them two to four weeks before the last average frost date.

Columbines are lovely wildflowers, and the Rocky Mountain columbine is an excellent type that survives harsh winters! It’s the state flower of Colorado, growing wild in alpine environments throughout the state. Grant it lots of sunlight and fertile, well-drained soil. The only condition this columbine dislikes is soggy, wet dirt.
Like many native perennials, this plant has a cold stratification requirement. This means the seeds must undergo weeks of freezing temperatures before they germinate. Plant them 10 to 12 weeks before the last frost date in your region so they receive the cold they need.
Inkberry

Inkberry is aptly named for its bright black fruits that form at summer’s end. They’re inky black. Although inedible, they provide delicious food for birds and small creatures looking for a winter snack. Salt, cold, and wet tolerant, this native plant excels in many conditions. It’s perfect for that tough spot in your yard where nothing else will grow!
Grant inkberry some winter protection, as it’s an evergreen shrub that suffers below zone 5. Add extra compost or leaf mold onto the soil around the shrub’s base. When hard freezes approach, consider adding frost cloth around the branches. Old bedsheets work well if you don’t have horticultural frost cloth!

Highbush cranberry isn’t a cranberry, though it sprouts fruits that resemble cranberries! The shrub is incredibly frost-resistant and grows well in bright or shady conditions. It dislikes warm, hot summers and will prefer partial shade in the hottest areas.
Highbush cranberries are deciduous; their leaves turn bright red in autumn before falling to the ground. This allows them to survive icy storms, as their woody stems are more resilient than thin leaves.
The red fruits are edible for gardeners and birds! You may have to battle local birds to get to them first. Be sure you’re collecting American highbush cranberries, as there is a European lookalike species with bitter, inedible fruits.

Silverberry towers over other low-growing shrubs, reaching up to 15 feet tall! Though it reaches tree heights, it grows with many stems in a bush-like structure. Gray-green leaves emerge in spring and fall off in autumn, revealing white, mealy berries. Browsing animals love eating the leaves, so be sure to leave them be!
Though this shrub is winter hardy, it’s intolerant of the heat in warm zones 7 and above. Use it as a windbreak or living hedge in cool, temperate regions throughout the northern U.S.
Many growers plant Russian olive, Elaeagnus angustifolia, though it’s readily displacing the native silverberry, Elaeagnus commutata. Plant native shrubs like silverberry to help bolster their resistance to invasive species!
