F. squarrosa is a native perennial graminoid that is a member of the Cyperaceae family . Species in this family grow reproductive units in the form of spikelets, which contain highly simplified flowers . F. squarrosa has alternate simple leaves shaped linearly, and contains a fibrous root structure like most Monocots .
The species can be found in the Southeast United States, ranging from Texas to Virginia, as well as in the Northeast in Maryland, New Jersey, and New York . It becomes more rare in communities located in Tennessee, Delaware, and New Jersey .
F. squarrosa can be found in mesic communities, including sphagnous bogs,  and can be found infrequently in pine-palmetto communities and wet prairies . As well, F. squarrosa is present in habitats ranging from wet sandy loams of roadside depressions and other wet loamy sand disturbed sites. 
Associated species - Eleocharis tuberculosa, Gentiana saponaria, Bartonia paniculata, Platanthera cristata, Pyrus arbutifolia, and Viburnum nudum .
Flowering time ranges continuously from August until October, while fruit development has been seen in the months of May and October. 
Sphagnous bogs and other similar communities are fire dependent due to their high acidity, which makes F. squarrosa dependent on fire frequency .
