Ground cherries grow almost wherever there is ground. We have two species in the area; both produce edible fruit inside their little Japanese lanterns, although it’s not usually much good until a week or two after it falls off the plant. (The papery lantern is toxic, so don’t eat it.) These pictures are of Physalis pubescens.
The flowers face downward and so are easily missed, but they’re worth examining closer. The color is primrose yellow with mahogany splotches around the center. They look like little Tiffany lanpshades, almost always held wide open and parallel to the ground.
