Native Plants by State, Three Layers
Published:
Roughly 40 million acres of the United States is lawn. The usual native plant argument is that you should convert it, and most people never will. The more useful version, and the one these pages are built around, is that the edges, the borders and the tree layer around the turf you are keeping can do an enormous amount of ecological work on their own. This cluster covers 114 species verified across 50 states and the District of Columbia, organized into a canopy layer, an understory layer and a flowering ground layer, with every wildlife figure carrying its published source and its level.
Start with your state
The native plant finder returns a three layer planting for any state: one canopy tree, one understory shrub and one flowering ground layer perennial, each with the wildlife it supports and its growing conditions. How every figure is sourced, and where the evidence is genuinely contested, is on the methodology page.
Why the tree layer comes first
North America has lost more than 3 billion breeding birds since 1970 (Rosenberg et al., Science, 2019). Terrestrial birds raise their young on insects, and a single chickadee brood eats roughly 6,000 to 9,000 caterpillars before it fledges. Those caterpillars come overwhelmingly from native woody plants, and they are not evenly distributed: a small minority of plant genera, around 14 percent, support the large majority of caterpillar species. That is why the canopy choice outweighs every other decision in a yard, and why these pages rank by genus level host counts rather than by how a plant looks.
The scale argument is the other half of it. About 70 percent of the ornamental species sold in United States nurseries over two centuries were not native to the continental US, according to a 2022 peer reviewed analysis, so the default suburban yard is assembled largely from plants the local food web cannot use. And only about 13 percent of the country has protected status, which means most of the land where habitat could exist is privately held. Whether a planted yard amounts to restoration is contested, and we set out both sides on the methodology page rather than pretending it is settled.
Native plants by state
49 of the 114 verified species carry a USDA drought tolerance of High or Medium, which is what makes them the constructive answer to the watering restrictions we track all summer.
Common questions
What are the three layers?
A canopy tree, an understory shrub or small tree, and a flowering ground layer perennial. Gardens work as communities rather than collections. The canopy and understory produce most of the caterpillars that birds feed their young, and the ground layer keeps pollen and nectar available from spring through fall.
Is this telling me to get rid of my lawn?
No. Most people are not removing their lawn and this does not ask them to. The edges, the borders and the tree layer can do an enormous amount of ecological work without touching the turf, and that is what these pages are built around.
How do you confirm a plant is native to a state?
Each species is checked against the USDA PLANTS Database for its recorded distribution in that state and its nativity status for the continental region the state sits in. Anything flagged introduced for that region is dropped. Eight candidate species were dropped outright because USDA returned no exact accepted name match.
Why is there no Hawaii page with plants on it?
Every species in this dataset that USDA records in Hawaii is flagged introduced there rather than native. Rather than pad the page, the Hawaii page says so and points to local resources instead.
If you are converting an area rather than edging it, the lawn alternatives guide covers ground layer substitutes in more depth, and the xeriscape cluster covers the low water approach state by state.
