You’ll find it naturally occurring in coastal plains, bogs, and other wetland areas throughout these regions.
A Word of Caution: Rarity Status
Before you rush out to find this plant, there’s something important you should know. In New Jersey, narrowfruit horned beaksedge has a rarity status of Listed Pinelands, Highlands Listed, S2, which means it’s considered imperiled in that state.
