Keystone Native Plants for Pollinator Paradise

Some plants ARE better than others - keystone species support more wildlife than any other plant, keeping the natural world buzzing.

Imagine your garden as a bustling metropolis, teeming with life. Butterflies flit between vibrant flowers, bees buzz industriously, and birds chirp merrily as they flit from branch to branch. This vibrant scene isn't just a dream; it's a reality you can cultivate in your own backyard by incorporating keystone native plants.

Understanding Keystone Native Plants

Keystone native plants are the ecological powerhouses of the plant world. They exert a disproportionately large influence on the health and stability of an ecosystem, acting as linchpins that support a wide variety of other organisms. 

Coined by renowned entomologist and Garden for Wildlife collaborator Dr. Doug Tallamy, the term "keystone" refers to a species that plays an outsized role in its ecosystem. Just like the keystone holds up an arch, keystone plants hold up the web of life. Dr. Tallamy's research has revealed a fascinating statistic: a mere 14% of native plants support a whopping 90% of our caterpillar species. These caterpillars, in turn, are the lifeblood of countless birds, providing essential food for their young.

"We have this misconception that all plants are created equal," says Dr. Tallamy. "But the reality is that some plants are much more ecologically valuable than others." 

These plants have co-evolved alongside the local fauna, creating a web of interdependent relationships. They provide essential food and shelter for a diverse range of creatures, from the tiniest insects to majestic birds of prey.

By incorporating keystone plants into your landscape, you're not just adding beauty, you're actively contributing to a thriving ecosystem in your own backyard.

Examples of Keystone Native Plants Across North America


The specific keystone plants will vary depending on your region. Here's a diverse selection to showcase the wide range of benefits they offer:

Native Keystone Trees

Quercus  oak treeOak (Quercus spp.): Dr. Tallamy's research reveals that native plants support a vastly greater diversity of insects compared to their non-native counterparts. In fact, a single species of native oak tree can host over 500 species of caterpillars—a critical food source for birds and other wildlife. By nurturing these keystone plants, we provide essential resources for the entire food web, laying the foundation for healthy, thriving ecosystems.

These majestic giants provide food (acorns) for a vast array of creatures, from squirrels and deer to insects and even mammals. Their leaves decompose to create nutrient-rich soil, while their branches offer crucial nesting sites for birds.  

Pine Trees (Pinus spp.): Pine trees are keystone species in many coniferous forests. They provide food and habitat for numerous species, including birds, squirrels, and insects. Pine forests also play important roles in regulating water flow, preventing soil erosion, and maintaining biodiversity.

Hickory Trees (Carya spp): Hickories are native keystones for wildlife in North American ecosystems. Their nutritious nuts sustain a wide array of species, including squirrels, birds, and mammals. As dominant canopy trees, they provide habitat, shade, and essential resources, contributing significantly to biodiversity and ecosystem stability.


Native Keystone Shrubs

Native shrubs also act as a cornerstone in the food web of your garden. Their berries are a primary food source for many birds, helping them survive during critical times like migration or winter. Additionally, the insects that feed on native shrubs serve as prey for various bird species, making these shrubs integral to the survival of countless wildlife.

Aster (Symphyotrichum spp.): Asters are a genus of perennial flowering plants in the family Asteraceae. There are around 170 species of asters, most of which are native to Eurasia and North America. They are known for their daisy-like flowers that come in a variety of colors, including purple, pink, white, and blue. Asters bloom in late summer and fall, and they are a valuable food source for butterflies, bees, and other pollinators.

Heliopsis helianthoides, oxeye sunflower native plantSunflowers (Helianthus spp): many species in the Helianthus genus, commonly known as sunflowers, are considered native keystone plants in North America! Sunflowers produce large heads full of seeds, which are a vital food source for many birds, including finches, chickadees, and goldfinches. In addition, the nectar in their flowers attracts a wide variety of pollinators like butterflies, bees, and beetles. Sunflowers also provide habitat for a variety of insects, including caterpillars and aphids. These insects, in turn, are a food source for other animals, such as birds and bats. 

Keystone Native Grasses

Native grasses are not a direct replacement for turf lawn, but instead have their own beauty and benefits.

Little bluestem provides critical habitat for many insect species, including caterpillars which are a vital food source for birds. In fact, little bluestem is a host plant for nine different skipper species!

Benefits of Planting Keystone Native Plants

There are numerous advantages to incorporating keystone native plants into your landscape:

Supporting Local Wildlife

By providing food and shelter for pollinators, birds, and other animals, native plants create a thriving ecosystem in your own backyard. This fosters biodiversity and helps to maintain the delicate balance of nature. Studies by entomologist Dr. Doug Tallamy (Garden for Wildlife collaborator) have shown that landscapes with keystone plants support 70-75% more caterpillar species than those without them, highlighting the crucial role these plants play in the food chain.

Enhancing Pollination

Many native plants are specifically adapted to attract pollinators like bees, butterflies, and hummingbirds. Perfect for your pollinator garden! These pollinators are essential for the reproduction of many flowering plants, including fruits and vegetables we rely on. A single bee visit can pollinate hundreds of flowers, ensuring a bountiful harvest and healthy ecosystems.

Promoting Natural Pest Control

Native plants are nature's pest control! A healthy ecosystem with a diverse population of beneficial insects helps to keep pest populations in check naturally. Keystone plants often attract predator insects that feed on harmful insects, reducing the need for pesticides. This creates a safer environment for you, your family, and your pets.

Reducing Maintenance Needs

Native plants are adapted to the local climate and soil conditions, requiring less water and fertilizer than non-native species. This translates to lower maintenance needs for your garden, saving you time and money. Additionally, native plants are often more resistant to pests and diseases, further reducing the need for interventions.

Creating a Beautiful and Sustainable Landscape

Native plants offer a wide variety of shapes, sizes, colors, and textures, allowing you to create wildlife garden design that reflects the natural beauty of your region. From vibrant wildflowers to majestic trees, native plants offer endless possibilities for creating a garden that is both aesthetically pleasing and ecologically beneficial.
