I found a fairly large patch of this native perennial at a local park. It's growing near the edge of a railway in a somewhat disturbed site in partial sun. What drew me in was the noise coming from bees who were buzz pollinating the flowers.
Another very similar native Ground Cherry is the Virginia Ground Cherry (Physalis virginiana), the major difference between the two is leaf shape. The Virginia has narrow lance-shaped leaves, and the Clammy has wide oval leaves.
Have you seen Clammy Ground Cherry before?
See map below for native range.
