Our Top 5 Favorite Native Plants for Biodiversity by Region

What is biodiversity? It’s a big term that measures how many animal and plant species are thriving in an area. Plant native plants, and you increase native animal populations. Learn which species are our favorites for each region alongside native plant gardener Jerad Bryant.

Various vibrant wildflowers, including red, yellow, and purple blooms, rise gracefully on slender stems against a green meadow backdrop.

Native plants are all the rage! Not only are they gorgeous ornamentals for gardens, but they’re also beneficial for pollinators, birds, and mammals. Flowers provide nectar and pollen for bugs, and leaves are a food source for caterpillars, deer, and snails. 

Large trees are indispensable habitats for squirrels, nesting birds, and small mammals. They provide shade and privacy below their canopy, making way for deer, bears, and cougars to come in. However, increasing biodiversity doesn’t have to start with a giant tree—small changes make big impacts.

When you plant wildflowers, they invite bugs. Birds and rodents eat bugs, and large mammals eat them in turn. Simply add a few native perennials and shrubs this year, and you’ll start a snowball effect of biodiversity boosting. Any native species in your yard can be beneficial, especially if its common in your local area. This list will help you grow your backyard into a dynamic ecosystem alive with activity. 

Northwest

We’ll start our tour with the northwestern section of North America. This space includes Oregon, Washington, northern California, and parts of Idaho. Coastal climates experience heavy, frequent rainfall, while eastern regions are dry, mountainous, and cold in the winter.

Showy Milkweed
