Also known as the Florida hedgehyssop, G. floridana is a native annual forb that is a member of the Scrophulariaceae family [1].


G. floridana is found in the Southeast United States, ranging from Louisiana and Florida to less frequently found in Tennessee [1].



G. floridana can be found in spring runs, steam banks, and blackwater swamps [2]. It has specifically been seen in shaded wet muck of floodplains, and partially shaded mesic firebreak trails. [3]

G. floridana has been observed to flower in March [4], but it has been seen to flower in April and May as well. Fruiting time ranges from March until April. [3]
