Common Ground Cherry (Long-Leaved Groundcherry; Wild Tomatillo)
Erect, branched perennial. Flowers arise singly from leaf axils, bell-shaped, about 1 inch long, sulphur to lemon yellow, the inner surface with 5 purplish spots or smudges toward the base that are sometimes merged into a ring. Blooms May–September. Leaves alternate, long petioled, either entire or with lobelike teeth, the margins of the 2 sides unsymmetrical, ovate. Fruit the “ground cherry,” a berry in a crisp, papery husk, which is 5-sided, pointed, and lanternlike.
Similar species: There are 13 Physalis species recorded for Missouri. All share the characteristic balloonlike, papery husk around the berry, which is why these plants are called “husk tomatoes.”
