It takes tough landscaping to survive The Steel City’s harsh winters. You need plants that can handle the cold conditions and change of seasons. By planting species that are native to Pennsylvania, you not only give your yard a fighting chance of looking great, but you also save time, money, and effort on landscaping.

There are several reasons why you should plant native species in your Pittsburgh backyard:


Low maintenance: Native plants have naturally evolved to survive their environment and climate conditions. Since they’re already acclimated to the environment, most native plants require less care.

Durable: Many native plants are resistant to disease, insects, and environmental conditions such as drought, wind, and freezing temperatures.

Good for the environment: Native plants play an important role in preserving natural landscapes and ecosystems in Pennsylvania. Many different types of wildlife depend on native plants for food and shelter. By having native plants, you are supporting birds, bees, butterflies and more, while enjoying their daily visits to your yard. 

How do you choose the best native plants for your yard?

Pittsburgh is in USDA hardiness zone 6B. Native plants can withstand lows down to 0 degrees Fahrenheit and soil conditions that are consistently dominated by highly acidic clay and silt loam soil.

There are around 2,100 native plants in Pennsylvania. We have put together a list of 9 favorite native shrubs, trees, and wildflowers for your Pittsburgh property.

Do you have a problem with critters tearing up your garden? This plant is very resistant to both deer and rabbits. It’s also disease and pest-resistant.

Smooth azaleas are fast-growing compared to other azalea varieties and they are one of the most durable types of native white azaleas. However, this plant is drought-sensitive and grows best in moist environments such as swampy forests, bogs, and around streams.

Where to find native plants

As interest in native plants increases, they are starting to become as easily accessible as non-native species. Right now there are three primary ways to find and purchase native plant species in Pennsylvania:

  • State parks in Pennsylvania host native plant sales in the spring. Check out the Pennsylvania Department of Conservation and Natural Resources website to find out which parks are currently hosting native plant sales. 
  • Pennsylvania Native Plant Society is a conservation organization advocating for increased native species diversity throughout the state. They host an annual native plant festival and other events throughout the year. 
  • Native plant nurseries also carry some types of native plants. Be sure to call or check their website ahead of time to ensure they carry the plants you’re looking for. 

Including native plants in your Pittsburgh garden is beneficial to both you and the environment. Native plants are more often drought tolerant compared to non-native plants. They attract and support native wildlife, bringing in birds, bees, and butterflies to entertain you in the spring and summer.

If you’re looking for more native plants, look at the Pennsylvania Native Plant Society (PNPS) website. Make sure to look for plants that are suited for central and western Pennsylvania and thrive in USDA hardiness zone 6B.
