Rare Plants of Ohio


The status list for rare native Ohio plants is revised every two years. This list became effective on December 31, 2018. State status is determined using information stored in the Ohio Natural Heritage Database.

A species is considered presumed extirpated (X) when no valid records are known from the last 20 years. Species designated as added (A) have been recently included in the Division's rare plant inventory and sufficient information is not yet available to assign an endangerment status.

Six Ohio plants are also included on the federal list of endangered and threatened species. Running buffalo clover (Trifolium stoloniferum) is federally endangered. Northern monkshood (Aconitum noveboracense) Lakeside daisy (Tetraneuris herbacea), small whorled pogonia (Isotria medeoloides), prairie fringed orchid (Platanthera leucophaea), and Appalachian spiraea (Spiraea virginiana) are federally threatened.

In addition to studies completed by our botanists, we rely heavily on volunteers and environmental consultants to track the status of rare plant populations. To report the occurrence of an Ohio endangered, threatened, or potentially threatened plant, please use the Rare Plant Survey form below.
