Also known as the Florida hedgehyssop, G. floridana is a native annual forb that is a member of the Scrophulariaceae family. Size class is between 0 to 1 foot with white to pink colored flowers.
G. floridana is found in the Southeast United States, ranging from Louisiana and Florida to less frequently found in Tennessee. More specifically, it ranges from northeastern Georgia and southeastern Tennessee south to eastern Georgia, northeastern Florida and the panhandle, Alabama, and Mississippi.
G. floridana can be found in spring runs, steam banks, and blackwater swamps . It has specifically been seen in shaded wet muck of floodplains, and partially shaded mesic firebreak trails. This species is also listed by the USDA Natural Resources Conservation Service as an obligate wetland species that only occurs in wetland habitats.
Associated species - Ludwigia palustris 
Species in the Gratiola genus were found in one study to appear in a community 13 years after a fire disturbance.
Conservation, cultivation, and restoration
It is considered endangered in the state of Tennessee yet not in any other region, but G. floridana should be monitored in the communities for its infrequency. As well, it is listed on the global status as G4 due to its restricted distribution and rarity, and is vulnerable in Georgia, critically imperiled in Tennessee and Mississippi, and possibly extirpated in Louisiana.
Medicinally, species in the Gratiola genus are said to have purgative properties.
