USDA records 209 of these 385 plants as native in fewer than half of Illinois’s counties. The map on each card shows where. A county with no record may never have been surveyed for that plant, so look at the counties around yours too, or use the county checker for an address-level answer.

Illinois’s own list regulates 33 plants. None of them is on this page. Illinois invasive plants has each one, with the rule cited.

What the map shows

Every plant here is native to Illinois. The map colours each county by what USDA records there.

Native
USDA records this plant growing wild in the county before European settlement.
Introduced
USDA records it in the county, but it arrived from elsewhere. Naturalised, not native.
Not recorded here
USDA has no record of it growing wild in the county, native or otherwise.

Where this comes from

Native range
USDA PLANTS county distribution layer, the same records behind the county checker.
Sold by nurseries
USDA PLANTS plant characteristics, Commercial Availability “Routinely Available”. It is a national flag, so a plant here can still be hard to find at a garden centre near you.
Plant details
USDA PLANTS: growth habit and duration from the plant profile; shade and wet-soil tolerance, bloom period, mature height and showy flowers, fruit or fall colour from the plant characteristics.
Left out
Any plant a state regulates as invasive or noxious, or that GRIIS flags as invasive in the lower 48, even where it is native. So is any species USDA records as both native and introduced in the lower 48, because the form nurseries sell is usually the introduced one.

They are a small part of Illinois's native flora, chosen because you can buy them. Each one carries a map of the Illinois counties where USDA records it growing wild.

This page lists 48 shrubs native to Illinois that nurseries routinely sell. The most widespread include American Black Elderberry, American Hazelnut and Smooth Sumac, each recorded as native in all 102 Illinois counties.

What wildflowers are native to Illinois?

Is my plant native to Illinois?

Search this page by common or scientific name. A plant missing from it can still be native to Illinois: the page lists only natives that nurseries routinely sell, and it leaves out any plant a state regulates as invasive. For a county-level answer on any plant, enter its name in Ezina's checker. Every answer links the record it came from.

Is a plant native to Illinois native everywhere in Illinois?

Not necessarily. USDA records nativity county by county, and 209 of the 385 plants on this page are recorded as native in fewer than half of Illinois's 102 counties. A county with no record may simply never have been surveyed for that plant, so read each card's map as where the plant is known to grow wild rather than as a boundary.
