Harper's beauty

Harperocallis flava
Plant Botanical Name: 
Harperocallis flava
Plant Threat Level: 

Harper's beauty has been federally listed as Endangered since 1979, but the few remaining populations have been decreasing since then, due to fire suppression, right of way mowing and altering site hydrology. For about four weeks every spring, the long-leafed plant sprouts a solitary yellow flower. Harper's beauty occurs in sunny wet prairies, seepage slopes, cypress swamps, pitcher plant bogs and today is sometimes seen in open, moist roadside ditches. It is found in only a few locations within a small area in and around the Apalachicola National Forest in the Florida Panhandle.
