Clammy groundcherry flowers arise at the junction of two branches or at a leaf axil on 1/4", arching pedicels that permit the flower to droop. The flowers are up to 3/4" across, consisting of a green calyx half the length of the flower with five triangular teeth, a funnel-shaped, pale-yellow corolla with five shallow lobes, five stamens with large, creamy-yellow anthers, and a single central pistil. In the interior of the corolla surrounding the ovary are five brown smudges, one on each corolla lobe, that merge centrally into a purple-brown ring covering the ovary. Both the pedicel and the calyx are also covered with fine white hairs. After fertilization, the flowers are replaced by green (later brown) hollow husks (a persistant calyx), heart-shaped in longitudinal section, covering a 1/2" diameter spherical, green fruit that becomes yellow when ripe. All parts of clammy ground cherry contain a glycoalkaloid poison called solanine that causes a series of unpleasant and sometimes potentially fatal symptoms; clammy groundcherry is avoided by mammalian herbivores. Only the RIPE fruit is edible.

Smooth groundcherry flowers are yellow, bell-shaped, with five purplish-brown patches near the center, five stamens with yellow or purple anthers, and a single pistil; the flowers are suspended from a purplish-green pedicel 3/4-1" long. After fertilization, the flowers are replaced by a tomatillo-like fruit (often with ten purple meridional lines) that is a green (later brown) hollow husk (a persistant calyx) that is heart-shaped in longitudinal section, covering a 1/2" diameter spherical, green miniature tomato that becomes yellow when ripe. All parts of smooth groundcherry contain a glycoalkaloid poison called solanine that causes a series of unpleasant and sometimes potentially fatal symptoms; smooth groundcherry is avoided by mammalian herbivores. Only the RIPE fruit is edible (said to taste like an underripe strawberry).
