Comptonia, or Sweet Fern as it is more commonly known as is found in the eastern United States from northern Georgia and as far west as Minnesota, and in Canada going south from Quebec. This plant has a confusing name as it is not a real fern.

The term bladder fern, or fragile fern, covers an entire genus, Cystopteris, of ferns known as Cystopteridaceae. All varieties of bladder fern can be found amongst rocky areas as well as soil, where they require light shade and only a moderate level of regular watering to thrive. It can sometimes be difficult to correctly identify a given specimen, due to the ease at which this genus hybridizes. The "bladder" nickname comes from the way their sori develop, appearing round and covered with swollen indusia. According to the USDA, bladder ferns grow in hardy zones ranging from 3a to 7b.
