Description
Also known as the Florida hedgehyssop, G. floridana is a native annual forb that is a member of the Scrophulariaceae family.[2] Size class is between 0 to 1 foot with white to pink colored flowers.[3]
Distribution
G. floridana is found in the Southeast United States, ranging from Louisiana and Florida to less frequently found in Tennessee.[2] More specifically, it ranges from northeastern Georgia and southeastern Tennessee south to eastern Georgia, northeastern Florida and the panhandle, Alabama, and Mississippi.[4]
Ecology
Habitat
G. floridana can be found in spring runs, steam banks, and blackwater swamps [4]. It has specifically been seen in shaded wet muck of floodplains, and partially shaded mesic firebreak trails.[5] This species is also listed by the USDA Natural Resources Conservation Service as an obligate wetland species that only occurs in wetland habitats.[2]
Associated species - Ludwigia palustris [5]
Phenology
G. floridana has been observed to flower in March [6], but it has been seen to flower in April and May as well. Fruiting time ranges from March until April. [5]
Fire ecology
Species in the Gratiola genus were found in one study to appear in a community 13 years after a fire disturbance.[7]
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.[2] 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.[8]
Cultural use
Medicinally, species in the Gratiola genus are said to have purgative properties.[9]
