B. nudata is a native perennial forb with fibrous roots that is a member of the Asteraceae family. The leaves are alternately arranged and oblanceolate in shape with entire margins. The flowers are yellow and give way to achene fruits (a dry fruit with a single seed).[1][2]


B. nudata is found in the Southeast United States, ranging from Texas to North Carolina[1]; however, it is most frequent along the coast lines of lower Mississippi to North Carolina. When the species is split into the subspecies nudata and australis, nudata is widespread from North Carolina to Louisiana while australis is restricted to peninsular Florida.[3]



Bigelowia nudata is a wide-ranging species, mainly occurring in wet to mesic habitats,[4][5] and can be found in moist sandy loams of savannahs, pine barrens, and margins of swamps as well as rich sandy soils in wet prairies and open pinelands.[3] This species can also be found in disturbed sites such as front lawns and roadsides.[6]

B. nudata was found to decrease its occurrence or be unaffected in response to soil disturbance by roller chopping in South Florida. It has shown either resistance to regrowth or no change in growth in reestablished native forests that were disturbed by roller chopping.[7] It does not respond to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[8]

Bigelowia nudata is an indicator species for the Peninsula Savannas community type and is frequent and abundant in the Upper Panhandle Savannas, Lower Panhandle Savannas, and Panhandle Seepage Savannas community types as described in Carr et al. (2010).[9]

Associated species include Linum macrocarpum, Lophiola aurea, Sarracenia alata, Lachnocaulon digynum, Magnolia virginiana, Scleria baldwinii, and Syngonanthus flavidulus[10][11]


It flowers twice a year, in the spring as well as the fall ranging from October to May.[3] B. nudata has been observed to flower in January as well as June through November with peak inflorescence in July and September.[12]

Seed bank and germination

Besides seed germination, B. nudata is known to propagate and germinate through rhizomes.[3]

Fire ecology

B. nudata seems to respond positively to fire, due to seen increase in flowering after multiple burns over time have been conducted.[13]
