Plant Range Maps
These web sites provide information about the distribution of plant species, some by county. Use distribution data when selecting wildflowers or native grasses to plant. When viewing range maps, be aware that species may occur in counties immediately adjacent to the range limits. This is especially true when there is a “donut” in a range map – that is, a species does not occur in a county in which the species occurs in all of the surrounding counties.
When using any of these databases, search by scientific name. Searching for a species by common name often is unreliable. Many species have more than one common name, and a common name may refer to more than species. For example, a search for the common name blackeyed susan on the Atlas of Florida Vascular Plants web site finds three species, including the native wildflower Rudbeckia hirta. A search for the common name browneyed susan, which some people call Rudbeckia hirta, returns a hit of Rudbeckia triloba. And a search for the common name black-eyed susan returns no hits; in many databases, the SEARCH function only finds plants based on the exact spelling as it exists in that database.
