About this data — and why a county can look empty
“Native” means the USDA lists the plant as native to the region, and it has been recorded in the place you chose. Records come from USDA PLANTS county and state data.
Why a county can look empty. Records depend on where botanists have surveyed and reported. A county with few records — or none, shown hatched on the map as “not surveyed” — usually hasn't been studied much. It doesn't mean few plants grow there. Try a neighboring county or the whole state.
Rare plants. County locations of rare and at-risk plants are withheld to protect them, and county lists say how many were left out.
Safety. Hazard data is incomplete. An empty hazard list doesn't mean a plant is safe for children, pets or eating.
