Common name: clammy ground-cherry, ground cherry, husk tomato
Varieties: Physalis ambigua (A. Gray) Britton; P. heterophylla Nees; P. heterophylla var. ambigua (A. Gray) Rydberg; P. heterophylla var. clavipes Fernald; P. heterophylla var. heterophylla; P. heterophylla var. nyctaginea (Dunal) Rydberg; P. nyctaginea Dunal
"Annual or perennial, glabrous or pubescent herbs. Leaves petiolate, entire to coarsely dentate, the base tapered, subcordate or oblique. Flower axillary, solitary; the calyx tube expanding, papery and bluntly conical when mature, loosely enclosing the fruit. Corolla campanulate to subrotate, yellow, often with 5 dark spots in the base of the tube; stamens 5, erect, separate, anther yellow or blue, dehiscing by lateral slits berry somewhat mealy, 2-locular, globose."
"Rhizomatous, often viscid perennial 2-9 dm tall. Stem pubescence of glandular trichomes mixed with both long and short nonglandular trichomes. Leaves widely ovate or oblanceolate to triangular or lanceolate, 3-11 cm long, 3-8 cm wide, sinuate-dentate or coarsely and irregularly dentate, rarely subentire, weakly cordate. Calyx 7-12 mm long, lobes triangular to lanceolate, shorter than the tube; corolla 10-18 mm long or broad, with 5 brownish basal spots; anthers yellow or rarely bluish, 3.5-4.5 mm long. Berry ca. 10 mm in diam., the fruiting calyx 2.5-3 cm long, about as broad."
P. heterophylla is widespread in the eastern and central United States, north to adjacent Canada, and south to northeastern and Panhandle Florida.
P. heterophylla has been documented to grow in calcareous coastal hardwood hammocks, drying sand bordering woods, upland sandhills and annually burned longleaf pineland. It has also been observed growing in old biocontrol plots and a fallow quail food patch. It has been documented in moist sandy loam and in the loam soils of the Red Hills Region. Associated species include longleaf pine.
P. heterophylla has shown regrowth in reestablished longleaf woodlands that were disturbed by agriculture in South Carolina, making it an indicator species for post-agricultural woodlands.
This species is thought to be dispersed by consumption by vertebrates.
Physalis heterophylla has been observed to host sweat bees such as Lasioglossum pectinatum (family Halictidae), plant bugs such as Reuteroscopus ornatus (family Miridae), ground nesting bees such as Perdita halictoides (family Andrenidae), and plasterer bees from the Colletidae family such as Colletes latitarsis and C. willistoni.
Conservation, cultivation, and restoration
The fruit can be used as a substitute for tomatoes.
