Description
  • Global Rank: G2 - Imperiled

Hartwrightia floridana A. Grey ex S. Watson (Asteraceae) is a perennial wildflower found in open wet habitats in peninsular Florida from Nassau to Highlands County and in south Georgia. Hartwrightia is listed as state-threatened in Florida, where populations are in danger of extinction from habitat loss, fire suppression, and the draining and ditching of its wet habitats that include wet flatwoods, seepage slopes, depression wetlands, and wet prairies. The plant appears in the spring as a basal rosette of oblanceolate leaves (3-10 inches long) covered in sticky glands. The tall reproductive stems (3-4 feet tall) emerge in the spring and summer, and the purple disk flowers are born atop branched corymb inflorescences in late summer. All parts of this plant are covered in sticky glands, including the achene fruits that mature in the fall.

              For the CPC seed initiative project, H. floridana seeds were collected from the southernmost population in its range located in Highlands County, Florida. This protected population occurs in a cutthroat grass seepage slope complex on state-owned lands and is managed with prescribed fire by the Florida Fish and Wildlife Conservation Commission. This habitat type is a unique plant community found almost exclusively in Polk and Highlands Counties in Florida. This open wet longleaf pine (Pinus palustris) community is dominated by a monoculture of cutthroat grass (Coleataenia abscissa), intermixed with a diversity of herbs, cinnamon fern (Osmundastrum cinnamomeum), and ericaceous woody species. Frequent fire helps maintain the health and structure of this rare plant community and the persistence of the H. floridana population.
