Physalis greenei Physalis crassifolia is a species of flowering plant in the nightshade family known by the common names yellow nightshade groundcherry and thick-leaf ground-cherry.

[1] It is native to the southwestern United States and northern Mexico, where it can be found in rocky, dry desert and mountain habitat.

This is a perennial herb producing a ridged, angular, branching stem approaching 80 cm long, taking a clumped, matted, or erect form.

The fleshy oval leaves are 1 to 3 cm long and have smooth, wavy, or bluntly toothed edges.

The star-shaped calyx of sepals at the base of the flower enlarges as the fruit develops, becoming an inflated, angled lanternlike structure about 2 cm long, which contains the berry.
