No plant on this page matches that.
USDA records 183 of these 266 plants as native in fewer than half of Idaho’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.
Idaho’s own list regulates 66 plants. None of them is on this page. Idaho noxious weeds has each one, with the rule cited.

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.

Questions
What plants are native to Idaho?
This page lists the 266 plants that USDA PLANTS records as native to Idaho and routinely available from nurseries: 32 trees, 58 shrubs, 84 wildflowers, 86 grasses and sedges, 5 ferns and 1 vine. They are a small part of Idaho's native flora, chosen because you can buy them. Each one carries a map of the Idaho counties where USDA records it growing wild.
What trees are native to Idaho?
This page lists 32 trees native to Idaho that nurseries routinely sell. The most widespread include Chokecherry, Mountain Maple and Thinleaf Alder, each recorded as native in at least 31 of Idaho's 44 counties.
What shrubs are native to Idaho?
This page lists 58 shrubs native to Idaho that nurseries routinely sell. The most widespread include Narrowleaf Willow, Yellow Rabbitbrush and Shining Willow, each recorded as native in at least 35 of Idaho's 44 counties.
What wildflowers are native to Idaho?
This page lists 84 wildflowers native to Idaho that nurseries routinely sell. The most widespread include Seep Monkeyflower, American Speedwell and Sticky Purple Geranium, each recorded as native in at least 31 of Idaho's 44 counties.
Is my plant native to Idaho?
Search this page by common or scientific name. A plant missing from it can still be native to Idaho: 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 Idaho native everywhere in Idaho?
Not necessarily. USDA records nativity county by county, and 183 of the 266 plants on this page are recorded as native in fewer than half of Idaho's 44 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.
