|Natural range of Physalis walteri from USDA NRCS Plants Database.|
Common names: Walter's groundcherry; Dune groundcherry
Synonyms: Physalis maritima M.A. Curtis; P. viscosa Linnaeus ssp. maritima (M.A. Curtis) Waterfall; P. walteri var. walteri; P. walteri var. glabra (Waterfall) D.B. Ward
P. walteri has been observed to be growing naturally on beach dunes and back dunes, in longleaf pine flatwoods, turkey oak sandridges, sandy banks bordering salt marhes,longleaf pine/wiregrass uplands, and slash pine flatwoods.  It has been seen in human disturbed areas such as pine plantations, old fields, plowed lots, vacant lots, roadsides near beaches, roadside ditches, pastures and levees, lawns, and clearing of a swamp forest.  The soil type associated with P/ walteri includes dry loamy sand, loamy sand, and calcerous soils (such as limerock).  Associated species include Tragia smallii, Pinus palustris, Physalis arenicola, Lobelia puberula, Quercus laevis, Sporobolus, Serenoa repens, Yucca, Lyonia, Lantana, Camara, Carex hyalinolepis, Melica mutica, Aristida, Pinus elliottii, and Helianthus debilis. 
This species is thought to be dispersed by consumption by vertebrates.
