Description
P. latiusculum is a native perennial forb that is a member of the Dennstaedtiaceae family.[2] It has short rootstalks that run horizontally up to a meter. The stalks are terminated by the leaf fronds that are broadly triangular in shape. The plants spread by spores or by the branching rootstalks.[3]
Distribution
The species is native to the southeast United States gulf coastal plain region, ranging from Louisiana and Kentucky to Maryland.[2]
Ecology
Habitat
The species is naturally found in dry woodlands, forests, and heath balds, up to 1600 meters in elevation.[4] It prefers dry, sandy or gravelly soils, and as a result is often found in abandoned fields and pastures.[5]
Fire ecology
Populations of Pteridium latiusculum have been known to persist through repeated annual burning.[6]
Herbivory and toxicology
Wild hogs will dig up and eat the roots of the ferns, but the plant is poisonous in large amounts to most other livestock.[7]
Conservation, cultivation, and restoration
Cultural use
If harvested when immature, the shoots can be prepared as a green much like asparagus.[8]
